Release 10.1.0

When a ComboBox editor is open in the DataGrid, one can use the arrow keys to go up and down the items of the combo in order to make a selection. When pressing Enter it is expected that the ComboBox gets closed and the DataGrid is still in edit mode for the same cell.

However, when the Enter is pressed - the ComboBox closes and the next row goes into edit mode - this behavior is erroneous.

For example we have set RowHeight to 26 with GridLineThickness = 1, GridLinesVisibility = Horizontal, and RowBackgroundStyle and AlternateRowBackgroundStyle with BorderThickness = 0.

The first row is 26px, the middle rows are 25px and the last row is 24px. So it seems the grid lines are included in the calculation of the RowHeight.

Type: Feature Request
1
In the current DataGrid implementation, the DataGrid will start with all the groups expanded. The only way to have any form of preference is to programmatically interact with the DataView after data is presented in the control  https://docs.telerik.com/devtools/maui/controls/datagrid/grouping/expand-collapse 

Requested Feature
A better approach that I am requesting a feature for is to have a property available for the DataGrid that sets this value ahead of time.

For example, you could add it as a BindableProperty on the GroupDescriptor class and on the GroupDefinition is to have an IsExapanded property.

Release 10.0.0 (2025 Q1)
In a scenario with dynamic removing and adding of columns, there is a memory leak when clearing the columns by invoking the Clear() method of the columns collection.

A work-around is to remove the columns one by one:

    for (int i = this.dataGrid.Columns.Count - 1; i >= 0; i--)
    {
        this.dataGrid.Columns.RemoveAt(i);
    }

Navigating to a DataGrid that is placed on third page first time the control displays when navigating to the third page. When navigating back to the second page and then go back to the third page the control do not display. 

On net 8 works as expected, the issue happens on net 9 and singleton approach is used.

We need an API through which we can get the currently visible in the viewport items. The API should take into account operations like sorting, filtering and grouping.

Release 10.0.0 (2025 Q1)

when applying Grouping and RowHeight to the DataGrid and expand the row details, the following happens -> The DataGrid in the RowDetails only appears for alternate rows. 

In addition the RowHeight does not apply to the Grouping Row.

Workaround:

Remove the RowHeight from the DataGrid and set the CellContentStyle property to the columns and set the TextMargin to the DataGridTextCellStyle, and ButtonMargin to the DataGridToggleRowDetailsCellStyle. Here is an example when setting them to 0:

            <telerik:DataGridTextCellStyle x:Key="cellStyle"
                                           TextMargin="0"/>


            <telerik:DataGridToggleRowDetailsCellStyle x:Key="toggleStyle"
                                                       ButtonMargin="0"/>


            <telerik:RadDataGrid.Columns>
                <telerik:DataGridToggleRowDetailsColumn CellContentStyle="{StaticResource toggleStyle}"
                                                        IsFrozen="True"/>
                
                <telerik:DataGridTextColumn PropertyName="Country"
                                            CellContentStyle="{StaticResource cellStyle}"
                                            IsFrozen="True" 
                                            CanUserReorder="False"  />
                
                <telerik:DataGridTextColumn PropertyName="Capital" 
                                            CellContentStyle="{StaticResource cellStyle}" />
            </telerik:RadDataGrid.Columns>

I have overridden the CreateGroupDescriptor() method to apply custom grouping on a column using the built-in grouping. However it seems I cannot get information whether grouping on this column is applied. I checked that IsGrouped and CanGroupBy properties are internal.

Issue description:

When the grid contains, after filtering out ,no rows the "Empty template" is not used/displayed.

Tested on Windows,  with "Telerik_UI_for_dot_NET_Maui_7_1_0_Dev\Examples\ControlsSamples", Example "Empty Template".

Steps to reproduce:

  1. Open example  "Empty Template"
  2. In "Configuration" set "Items source" to "Non-empty collection"
  3. Set filter in "Order Id" to "Is equal to" = 999

Expected behavior:

Display/Use "Empty template" when there are no visible records.

...or to make it more consistent with the current implementation - add new option "ItemsSourceNullOrEmptyOrFilteredOut" to the enum "EmptyContentDisplayMode":


namespace Telerik.Maui.Controls;
//
// Summary:
//     Defines the modes for displaying empty content.
public enum EmptyContentDisplayMode
{
    //
    // Summary:
    //     Displays the empty content view only when the ItemsSource is null.
    ItemsSourceNull,

    //
    // Summary:
    //     Displays the empty content view when ItemsSource is null or when the source is
    //     empty (has zero items).
    ItemsSourceNullOrEmpty,
    
+    //
+    // Summary:
+    //     Displays the empty content view when ItemsSource is null or when the source is
+    //     empty (has zero items) or when all items are filtered out. (either by filter or by search)
+    ItemsSourceNullOrEmptyOrFilteredOut
}    


Best regards,

Release 10.0.0 (2025 Q1)
when a RadDataGrid has collapsed groups, trying to edit a row that comes after one of the collapsed groups (and a little bit of scrolling) is impossible, because the RadDataGrid scrolls back to the top.
