I have the following logic for my View, which has a RadGridView control (add to form at design-time).

GUI is a lightweight view, Controller does the heavy lifting. That part is all good.

 

However setting the column name and column autosize stuff is a little more "over-complicated" than I'd wish to see. It all works though.

Would be nice to have a "GridViewTextBoxColumnAttribute" as per below, for properties on Custom datasource objects to achieve the same thing in a more concise way.

Or am I missing something and there is a much easier way to do what I want?

 

I have a number of datasource classes: MyObject, MyCar, MyDog, MyWhatever... that ALL have different property names and datatypes, but may or may-not have the same column name or MasterTemplate style.

 

Also BestFitColumns is a function of the MasterTemplate, would be nice if it were a property for consistency sake (call to internal function encapsulated in the Set etc), as from a Telerik user's perspective it's just an enum. Then it would be setable in the SmartTag window as well, as functions can't be assigned to.

 

  public partial class RadForm1 : Telerik.WinControls.UI.RadForm, IView
    {
        public RadForm1)
        {
            InitializeComponent();
        }

        private void RadForm1_Load(object sender, EventArgs e)
        {
            var x = new Controller();
            x.SetTemplate(this);           
        }

        public Telerik.WinControls.UI.RadGridView RadGridView()
        {
            return this.radGridView1;
        }
    }

    public class Controller
    {
        public void SetTemplate(IView view)
        {
            var View_RadGrid = view.RadGridView();
            View_RadGrid.MasterTemplate.AutoGenerateColumns = false;
            View_RadGrid.MasterTemplate.AutoGenerateHierarchy = false;
            View_RadGrid.MasterTemplate.AllowColumnResize = false;
            View_RadGrid.MasterTemplate.BestFitColumns(Telerik.WinControls.UI.BestFitColumnMode.AllCells);

            var cols = new List<Telerik.WinControls.UI.GridViewDataColumn>()
            {
                new Telerik.WinControls.UI.GridViewTextBoxColumn("DisplayName1"),
                new Telerik.WinControls.UI.GridViewTextBoxColumn("DisplayName2")
            };
            View_RadGrid.MasterTemplate.Columns.AddRange(cols.ToArray());

            View_RadGrid.DataSource = new List<MyObject>() 
            { 
                new MyObject() { DisplayName1 = "1", DisplayName2 = "2" }, 
                new MyObject() { DisplayName1 = "3", DisplayName2 = "4" } 
            };
        }

        private class MyObject
        {

            public string DisplayName1 { get; set; }

            [GridViewTextBoxColumnAttribute("DisplayName2", BestFitColumn = Telerik.WinControls.UI.BestFitColumnMode.AllCells, AllowColumnResize = false)]
            public string DisplayName2 { get; set; }
        }
    }

    public interface IView
    {

        public GridViewTextBoxColumnAttribute(string fieldName)
        {
            this.FieldName = fieldName;
        }

To reproduce: please run the attached sample project and follow the steps illustrated in the attached gif file:

Scrolling to a newly added row does not work when inner templates are visible.

Add data to the inner templates of several rows near the bottom using the button.
Expand these inner templates so they are all visible.
Scroll back up to the top.
Add a new item to the outer grid normally.
The table will jump to where it things the new item is but will fall short, instead scrolling to a location in one of the inner templates.
Workaround:

        private void RadGridView1_UserAddedRow(object sender, GridViewRowEventArgs e)
        {
            foreach (GridViewRowInfo    row in this.radGridView1.Rows)
            {
                if (row.IsExpanded)
                {
                    row.IsExpanded = false;
                    row.IsExpanded = true;
                }
            }
        }

How to reproduce:

1. Click DrugName Filter Icon.
2. Uncheck Combivent
3. OK
4. Click name Filter Icon
5. Uncheck Christoff
6. OK
7. Click DrugName Filter Icon
8. Uncheck Dilantin
9. OK

In this scenario the grid should display only 2 rows but it displays 3.

public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
    public List<Drug> DrugList { get; set; }

    public RadForm1()
    {
        InitializeComponent();
        DrugList = new List<Drug>();
        LoadDrugList();
        radGridView1.DataSource = DrugList;
        radGridView1.EnableFiltering = true;

        this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
        this.radGridView1.MultiSelect = true;
    }

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);

        radGridView1.MasterTemplate.ShowFilteringRow = false;
        radGridView1.MasterTemplate.ShowHeaderCellButtons = true;
    }

    void LoadDrugList()
    {
        DrugList.Add(new Drug { Dosage = 25, DrugName = "Indocin", Name = "David"});
        DrugList.Add(new Drug { Dosage = 50, DrugName = "Enebrel", Name = "Sam" });
        DrugList.Add(new Drug { Dosage = 10, DrugName = "Hydralazine", Name = "Christoff"});
        DrugList.Add(new Drug { Dosage = 21, DrugName = "Combivent", Name = "Janet"});
        DrugList.Add(new Drug { Dosage = 100, DrugName = "Dilantin", Name = "Melanie"});
    }

}

Workaround: use a custom filter popup
public partial class RadForm1 : Telerik.WinControls.UI.RadForm

    public List<Drug> DrugList { get; set; }

    public RadForm1()
    {
        InitializeComponent();

        radGridView1.DataSource = DrugList;
        radGridView1.EnableFiltering = true;

        this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
        this.radGridView1.MultiSelect = true;

        this.radGridView1.FilterPopupRequired += RadGridView1_FilterPopupRequired;
    }

    private void RadGridView1_FilterPopupRequired(object sender, FilterPopupRequiredEventArgs e)
    {
        e.FilterPopup = new CustomRadListFilterPopup(e.Column);
    }

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);

        radGridView1.MasterTemplate.ShowFilteringRow = false;
        radGridView1.MasterTemplate.ShowHeaderCellButtons = true;
    }

    void LoadDrugList()
    {
        DrugList.Add(new Drug { Dosage = 25, DrugName = "Indocin", Name = "David"});
        DrugList.Add(new Drug { Dosage = 50, DrugName = "Enebrel", Name = "Sam" });
        DrugList.Add(new Drug { Dosage = 10, DrugName = "Hydralazine", Name = "Christoff"});
        DrugList.Add(new Drug { Dosage = 21, DrugName = "Combivent", Name = "Janet"});
        DrugList.Add(new Drug { Dosage = 100, DrugName = "Dilantin", Name = "Melanie"});

To reproduce:
Add a RadGridView and use the following code. When you expand the first row, the vertical scrollbar is not correct. Scrolling down changes its size. However, if you expand the last row, it takes few seconds to open.

Second scenario:
In addition of the following code, if you change the TableElement.PageViewMode to PageViewMode.ExplorerBar, expanding the first row takes few seconds to load the hierarchical data as well.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();

        List<Item> items = new List<Item>();
        List<SubItem> subItems = new List<SubItem>();

        for (int i = 1; i <= 3; i++)
        {
            Item item = new Item(i, "Item" + i);
            
            for (int j = 1000; j <= 2010; j++)
            {
                subItems.Add(new SubItem(j, "SubItem" + j, i));
            }

            items.Add(item);
        }

        this.radGridView1.DataSource = items;
        this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

        GridViewTemplate template = new GridViewTemplate();
        template.ReadOnly = true;
        template.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

        GridViewRelation relation = new GridViewRelation(this.radGridView1.MasterTemplate, template);
        relation.ParentColumnNames.Add("Id");
        relation.ChildColumnNames.Add("ItemId");
        this.radGridView1.MasterTemplate.Templates.Add(template);
        this.radGridView1.Relations.Add(relation);
        template.DataSource = subItems;
    }
}

public class Item
{
    public int Id { get; set; }

    public string Title { get; set; }

    public Item(int id, string title)
    {
        this.Id = id;
        this.Title = title;
    }
}

public class SubItem
{
    public int Id { get; set; }

    public int ItemId { get; set; }

Hello,

I am having issues with DateTime editor in the grid. We have custom date/time format for our dates - "HH:mm:ss dd-MMM-yyyy" and the datetime editor is set to free form date time with this mask. When user typed a value in the editor it is passed to FreeFormDateTimeProvider.Validate method, which calls DateInput.ParseDate. DateTimeLexer splits this kind of values just fine, but obviously time related tokens comes first and then the date related tokens.

Unfortunately DateTimeParser.Parse method is made the way that it parse date at first and then time from the tokens list. In my case this means time value is parsed and the date value is dropped to default. Why didn't you check that if after ParseDate and ParseTime calls the date portion is null but there are still remaining tokens in the list, so you may call ParseDate one more time?

Do you have any suggestion how could I resolve this issue? Everything related to date time parsing is not extendable at all, starting from DateInput, most of the classes and methods are not public and even some public methods are not virtual. Can I have the Telerik free form date time typing capabilities in the editor but still have time part before date part?

How can I enter the Value "" (empty string) in the traditional filter system (not Excel like filter).

The grid does not seem to accept an empty string as an argument to "Equals" through the UI.

Ideally I would like to extend the standard filter menu in traditional filtering (and the filter operator drop down in custom filtering dialog) to contain operators "Is Empty" "Is Not Empty" and "Is Null Or Empty", "Is Not Null And Not Empty"

Regards

Erwin

To reproduce: use the following code snippet, save the layout and load it afterwards. You will notice that only the master and the first child template are successfully loaded.

public Form1()
{
    InitializeComponent();
    DataTable dt = new DataTable();
    dt.Columns.Add("Id", typeof(int));
    dt.Columns.Add("Name", typeof(string));
    for (int i = 0; i < 5; i++)
    {
        dt.Rows.Add(i, "Parent" + i);
    }

    this.radGridView1.MasterTemplate.DataSource = dt;
    this.radGridView1.MasterTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;

    //child level 1
    GridViewTemplate template = new GridViewTemplate();
    template.DataSource = GetData(5, 20, 0, 5);
    template.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
    radGridView1.MasterTemplate.Templates.Add(template);

    GridViewRelation relation = new GridViewRelation(radGridView1.MasterTemplate);
    relation.ChildTemplate = template;
    relation.RelationName = "ParentChild";
    relation.ParentColumnNames.Add("Id");
    relation.ChildColumnNames.Add("ParentId");
    radGridView1.Relations.Add(relation);

    //child level 2
    GridViewTemplate template2 = new GridViewTemplate();
    template2.DataSource = GetData(20, 40, 5, 20);
    template2.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
    template.Templates.Add(template2);

    GridViewRelation relation2 = new GridViewRelation(template);
    relation2.ChildTemplate = template2;
    relation2.RelationName = "ParentChild";
    relation2.ParentColumnNames.Add("Id");
    relation2.ChildColumnNames.Add("ParentId");
    radGridView1.Relations.Add(relation2);

    //child level 3

    {
        s = dialog.FileName;
    }
    this.radGridView1.LoadLayout(s);
}


Workaround: grid templates for the inner levels are recreated after loading the layout. Their DataSource is null and the existing relations points to the old templates. Clear the relations and setup them again with the new  child template instances.

To reproduce: 

- Add items with the same display member open the drop-down and select the second.

- Select another control on the form and then reopen the popup.

- The first item is selected.

Workaround: 

class MyMultiColumnComboBox : RadMultiColumnComboBox
{
    protected override void OnLostFocus(EventArgs e)
    {
        if (this.DropDownStyle == Telerik.WinControls.RadDropDownStyle.DropDownList)
        {
            return;
        }
        base.OnLostFocus(e);
    }
}

Changing the DataSource or scrolling are slow.

Create a grid with more than 20 columns and add 5K rows for example. Maximize the form and try to scroll with mouse wheel. You will notice that the scrolling performance is worse compared to the normal state of the form with less visible visual elements.

Workaround: this.radGridView1.EnableFastScrolling = true; and use the scrollbar's thumb

Second workaround: use paging:  https://docs.telerik.com/devtools/winforms/gridview/paging/overview Thus, you will display as many rows as possible to display on the screen per page. Instead of scrolling, you will navigate through pages.

To reproduce:
- Filter a self-referencing grouped grid. 

Workaround:
private void _rgvFreeCodeValues_FilterChanged(object sender, GridViewCollectionChangedEventArgs e)
{
    foreach (var row in RgvFreeCodeValues.Rows)
        row.IsExpanded = false;
}

private void _rgvFreeCodeValues_FilterChanging(object sender, GridViewCollectionChangingEventArgs e)
{
    foreach (var row in RgvFreeCodeValues.Rows)
        row.IsExpanded = true;
}

Hi

I just found a strange issue using the latest bits of the Telerik RadGridView. 

I have a grid that contains ColumnGroupsViewDefinition. Inside one of the group, one of the column is a GridViewComboBoxColumn.

The grid shows correctly on the screen.

If I try to export it using GridViewSpreadExport, I get an exception saying "input string was not in a correct format".

The export works fine if:

-I don't have groups

-I export to HTML using ExportToHTML

-I export to HTML using ExportToCSV

 

Any help please?

This can be used for large amounts of data.

The scenario which should be covered is selecting some data from Excel and pasting in the new row of RadGridView. This is an easy way for inserting data in the grid.

To reproduce: run the attached sample project and activate the editor for the cell. You will notice that the row's height is now adjusted and single line text is displayed. It seems that the issue occurs because of the set Font property of the grid.

Workaround:  
        private void RadGridView1_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
        {
            e.Row.MinHeight = e.Row.Height + 3;
            RadTextBoxEditor tbEditor = e.ActiveEditor as RadTextBoxEditor;
            if (tbEditor != null)
            {
                tbEditor.Multiline = true;
            }
        }

        private void radGridView1_CellEndEdit(object sender, GridViewCellEventArgs e)
        {
            e.Row.MinHeight = 0; 
        }

To reproduce:
- Add ColumnGroupsViewDefinition and set ShowHeader to false. 
- Set AutoSizeRows to true.

Workaround:
Manually set the row height.
  ViewDefinition.ColumnGroups(0).Rows(0).MinHeight = 50

A possible workaround is to use the following KB and change how it is implemented to iterate the MasterTemplate.Rows collection instead of the ViewInfo.Rows collection

To reproduce:
1.Add a RadGridView with one column.
2.Select the form and in the Properties window, set the form's Localizable property to true.
3.Specify the column's HeaderText for the default language.
4.Set the form's Language property to French (France).
5.Specify the column's HeaderText for  French (France).
6.Set the CurrentUICulture before the InitializeComponent method to "fr-FR". If you run the application, the column is localized as expected.
7.If you get back to the designer and change the form's Language property back to Default you will notice that the column's HeaderText disappears.

Workaround: set the HeaderText programmatically according to the current language.
