I was creating a table with filters when I noticed that there is an option in the filters for 'EndsWith' but not one for 'DoesNotEndWith'. We use internal part numbers for our products where the last 3 digits determine the department in which the product was made. Because wildcards cannot be used within the RadGridView filters, I am having to create a unusual workaround. The same can be said about 'DoesNotBeginWith'.

Hi, 

I have to transfer data from gridview to a .xlsm file which is for the salary transfer to the bank from the application (Template given by the Bank).

Need to fill the cells from the loaded gridview to this template.

Please help; I have searched a lot but no luck.

Thank you very much.

Please refer to the following code snippet demonstrating how the comparer can be applied:

        public RadForm1()
        {
            InitializeComponent();
            this.radGridView1.EnableFiltering = true;
            this.radGridView1.ShowHeaderCellButtons = true;
            this.radGridView1.FilterPopupInitialized += radGridView1_FilterPopupInitialized; 
        }

        private void radGridView1_FilterPopupRequired(object sender, FilterPopupRequiredEventArgs e)
        {
            RadListFilterPopup popup = e.FilterPopup as RadListFilterPopup;
            if (popup != null)
            { 
                popup.MenuTreeElement.TreeView.TreeViewElement.Comparer = new MyComparer(popup.MenuTreeElement.TreeView.TreeViewElement);
            }
        }

        class MyComparer : TreeNodeComparer
        {
            public MyComparer(RadTreeViewElement treeView)
                : base(treeView)
            {
            }
            public override int Compare(RadTreeNode x, RadTreeNode y)
            {
                if (this.TreeViewElement.SortOrder == SortOrder.Descending)
                {
                    return x.Text.CompareTo(y.Text);
                }
                return x.Text.CompareTo(y.Text) * -1;
            }
        }

I might be missing something, but I have Hyperlinks in a column in my RadDatGridView.

 

I tried searching for a Support document explaining this, but didn't find any.

 

When the grid is exported to excel all data is coming across, but the column with hyperlink is not

a hyperlink in Excel.

 

Below is sample of the code used to make the "HyperLink" column in my grid.

                radGridView1.DataSource = dtResults;
                radGridView1.Columns.Remove("Path");
                GridViewHyperlinkColumn col = new GridViewHyperlinkColumn();
                radGridView1.Columns.Insert(5, col);
                col.Width = 200;
                col.FieldName = "Path";
                col.HeaderText = "Path";
                col.Name = "Path";

 

Coded used to do the Export....

               GridViewSpreadExport spreadExporter = new GridViewSpreadExport(this.radGridView1);
                spreadExporter.ExportVisualSettings = true;
                SpreadExportRenderer exportRenderer = new SpreadExportRenderer();

                spreadExporter.RunExport(filename, exportRenderer);

 

Thanks.

Hello,

In our Environment it's not possible to assign a GroupComparer to another GridView template then MasterTemplate. The GroupComparer property is always null after assignment.

It's possible to assign our custom comparer to the MasterTemplate and it will be triggered, but not in another template then MasterTemplate.

Best regards.

Add a new DeferredFilter property on RadGridView level which controls whether the filtering logic will be immediately preformed on each key stroke or only by pressing Enter.

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

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);

            };

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

    public interface IView
    {
        Telerik.WinControls.UI.RadGridView RadGridView();
    }

    public class GridViewTextBoxColumnAttribute : System.Attribute

        public GridViewTextBoxColumnAttribute(string fieldName)

Hello,

Please create a GridViewDateTimeOffsetColumn to support DateTimeOffset type.
A datetimeoffset editor would be good and support of nullable date types.

Thank you!

The new mode should allow copying of single cells even when having the SelectionMode set to FullRowSelect. The attached project features a possible workaround.

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.

This new API will be useful for implementing custom sorting scenarios when you need to have custom sorting only for a single column.

A similar API is available for the filtering functionality (MasterTemplate.DataView.FilterEvaluate)

Consider the case where there are many child views and you want to export only the ones that actually contain data. 
Currently, you can either export only one view or all. 

One should be able to pass all the views in the ChildViewExporting event.

The specified format in the DisplayFormat attribute should be considered when automatically generating the GridViewDateTimeColumn.

public RadForm1()
{
    InitializeComponent();

    List<Item> items = new List<Item>();
    for (int i = 0; i < 5; i++)
    {
        items.Add(new Item(DateTime.Now.AddDays(i)));
    }

    this.radGridView1.DataSource = items;
    this.radGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;
}

public class Item
{
    [System.ComponentModel.DisplayName("My Date")]
    [System.ComponentModel.DataAnnotations.DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
    public DateTime Date { get; set; }

    public Item(DateTime date)
    {
        this.Date = date;
    }
}
