Hi,

Following to the workaroud (flag IsSearchAsync) provided (https://feedback.telerik.com/Project/154/Feedback/Details/245938-fix-radgridview-having-groups-filters-sort-descriptors-and-search-query-in-t), we discovered two issues :

1) the behavior of the grid is changed while using IsSearchAsync as true or false (see 2018-08-01_1849_DragDrop_behavior_with_IsSearchAsync.swf video attached). When set to true, the line found by the searchbox is automatically reselected. When the flag is set to false, it's not the case.

2) while playing with drag&drop, after some time the grid became unstable (see 2018-08-01_1847_-_dragdrop_issue_with_IsAsyncSearch.swf video attached). You can see that at the beginning, the D&D works fine. At 0:20 I can't select any line, and when I try to D&D, it drops always the same customer. At 0:40 you can see that even the SearchBox is broken and the progressbar is looping forever

Use attached to reproduce.

Workaround:
Set the TableHeaderHeight again after loading the layout.

To reproduce: please refer to the attached sample project and gif file

Workaround:

            GridViewSpreadExport spreadExporter = new GridViewSpreadExport(this.radGridView1);
            spreadExporter.ExportFormat = SpreadExportFormat.Pdf;
            spreadExporter.ExportVisualSettings = true;
            SpreadExportRenderer exportRenderer = new SpreadExportRenderer();
            spreadExporter.RunExport(exportFile, exportRenderer);
            Process.Start(exportFile);

To reproduce: run the attached project and toggle the checkbox in the header cell of the child template. 

Workaround: use a custom GridCheckBoxHeaderCellElement

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.

Steps to reproduce:

  1. Click column header to sort.
  2. Click button which to export to Excel.
  3. The rows return to unsorted.
  4. Scroll down slightly and scroll back up and the sort is restored.

This happens after calling RunExport.

I attached a gif and a sample project.

UI for WinForms R2 2019 SP1 (version 2019.2.618)

June 19, 2019

RadGridView

NEW
  • New property inside GridViewSearchRowInfo: DeferredSearch. Gets or sets a value indicating whether grid will wait until enter key is pressed before it starts a search.

 

 

I have implemented this and it is exactly what I want and need, Thank you! 
However I thought I might point out that when you tab out it doesn't implement the search, only when you press enter.

And when you press the X to clear the search it clears the text box but not the search. the count of found and the highlighted finds remain

RadGridView data source contains date values from years 2018 and 2019. After adding Excel like filters to the RadGridView and selecting year 2019 no rows were displayed, even though some values did match the filter condition (see attachment).

In my gridview need support of different heights of rows. I solved it with the autosize property.

But now I have a side action that the header row and filter row also react to the autosize property.

Attached you can see this behaviour...

Here my code:

Grid.MasterView.TableFilteringRow.MinHeight = 40
Grid.AutoSizeRows = True

Is there a chance to separate data rows from filter and header row?

 

Regards,

Dimitri

Workaround:

AddHandler Me.RadGridView1.ChildViewExpanding, AddressOf RadGridView1_ChildViewExpanding 
AddHandler Me.RadGridView1.MouseDown, AddressOf RadGridView_MouseDown

Private Sub RadGridView1_ChildViewExpanding(sender As Object, e As ChildViewExpandingEventArgs)
    If lastClicked IsNot Nothing AndAlso e.ParentRow.Equals(lastClicked) Then
        e.Cancel = False
    Else
        e.Cancel = True
    End If

End Sub

Dim lastClicked As GridViewRowInfo

Private Sub RadGridView_MouseDown(sender As Object, e As MouseEventArgs)
    Dim expander As GridExpanderItem = TryCast(Me.RadGridView1.ElementTree.GetElementAtPoint(e.Location), GridExpanderItem)
    If expander IsNot Nothing Then
        lastClicked = DirectCast(expander.Parent, GridGroupExpanderCellElement).RowInfo 
    End If 
End Sub

Release R1 2019
To reproduce:
1. Add a RadMultiColumnComboBox and populate it with data.
2. Set the DropDownStyle property of the control to DropDownList
3. Set the EditorControl.AllowSearchRow and the AutoSizeDropDownToBestFit properties to true .
4. When you open the drop down and try to use the search row (e.g. clicking over the arrow buttons), the drop down is closed.

Workaround: 
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
    public RadForm1()
    {
        InitializeComponent();

        this.radMultiColumnComboBox1.EditorControl.AllowSearchRow = true;
        this.radMultiColumnComboBox1.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;
        this.radMultiColumnComboBox1.DropDownClosing += RadMultiColumnComboBox1_DropDownClosing;
    }

    private void RadMultiColumnComboBox1_DropDownClosing(object sender, RadPopupClosingEventArgs args)
    {
        Point position = this.radMultiColumnComboBox1.EditorControl.PointToClient(Cursor.Position);

        Telerik.WinControls.RadElement searchElement = this.radMultiColumnComboBox1.EditorControl.ElementTree.GetElementAtPoint(position);
        if (searchElement != null)
        {
            GridSearchCellElement parent = searchElement.FindAncestor<GridSearchCellElement>();
            if (parent != null)
            {
                args.Cancel = true;
            }
        }
    }
}

1. Create a new project and setup hierarchy
2. Add a large number of rows as child rows to the last row at first level
3. Run the project and try to expand the last row

- Create a new project containing RadGridView
- Build hierarchy with large text data in cells
- Set the AutoSizeRows property to true and AutoSizeColumnMode to Fill
- Run the project, scroll down and try to click on a cell

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
        {
            [GridViewTextBoxColumnAttribute("DisplayName1", BestFitColumn = Telerik.WinControls.UI.BestFitColumnMode.AllCells, AllowColumnResize = false)]
            public string DisplayName1 { get; set; }

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

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

    [System.AttributeUsage(System.AttributeTargets.Property)]
    public class GridViewTextBoxColumnAttribute : System.Attribute
    {
        private string FieldName;
        public Telerik.WinControls.UI.BestFitColumnMode BestFitColumn;
        public bool AllowColumnResize;

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