Release 7.0.0 (2024 Q2)
In Windows, when I press the up key or the down key while the data grid is on edit mode, the scroll bar moves even though it shouldn't.

In view mode, the scroll bar of the data grid moves only when the selected item is the first or last visible item in the display area of the data grid. But in edit mode, it moves regardless and it moves a lot more than usual.

I need a way for the scrollbar to behave the same for view and edit modes for a requirement in my project.

Release 5.1.0
The following code uses RadHighlightedLabel and manipulates the highlighted text by the Text of an Entry.

<telerik:RadDataGrid x:Name="dataGrid" AutomationId="dataGrid" AutoGenerateColumns="False">
                <telerik:RadDataGrid.Columns>
                    <telerik:DataGridTextColumn PropertyName="Country" HeaderText="HighlightedLabel">
                        <telerik:DataGridTextColumn.CellContentTemplate>
                            <DataTemplate>
                                <telerik:RadHighlightLabel UnformattedText="{Binding Country}"
                                                                           HighlightText="{Binding Source={x:Reference searchEntry}, Path=Text}"
                                                                           HighlightTextColor="Red"/>
                            </DataTemplate>
                        </telerik:DataGridTextColumn.CellContentTemplate>
                    </telerik:DataGridTextColumn>
                </telerik:RadDataGrid.Columns>
            </telerik:RadDataGrid>

Expected: When typing in the entry the text of the label should get highlighted and remove the highlight when the text of the entry is removed.

Actual: The highlighted text doesn't get updated and stays the same.

I want to exit edit mode and commit edit when hitting on Enter Key.

It works great for text column/cell.

But it does not work for numerical cells
   - Numerical cell still in edit mode by displaying a RadNumericInput within the cell.

Release 6.3.0

When cell is in edit mode, pressings enter key calls infinitely CommitEdit Execute method in custom scenario. 

1. When new item is added to the DataGrid source, the cell goes in edit mode

2. Pressing enter key executes additional logic and CommitEdit Execute method calls infinitely.

Workaround:

 Inside the CommitEdit CanExecure method, call the default can execute logic

public override bool CanExecute(object parameter)
    {
        return this.Owner.CommandService.CanExecuteDefaultCommand(DataGridCommandId.CommitEdit, parameter);
        //return true;
    }

Dynamic change of the IsEnabled property of the RadDataGrid does not affect the RowDetails, leaving the UI inconsistent.

In my case, the RadDataGrid is disabled initially (IsEnabled=False). Some data is loaded in the DataGrid. At runtime I set the IsEnabled property of the DataGrid to true. I am then able to expand row details. The issue is that the view in the row details has the IsEnabled property set to false.

I auto select the text in cell once the cell is in edit mode and SelectionOnFocus is set to SelectAll in the RadEntry element inside the CellEditTemplate. I have a timer that updates other columns value but not the value in the editable cell. Still the selection is lost when row data changes.

Release 5.1.0

When the selected item is set initially, the selected style is not applied to the row/cell.

Workaround: You can use a Dispatcher to workaround the issue, code looks as follows:

this.Dispatcher.StartTimer(TimeSpan.FromMilliseconds(200), () =>
        {
            if (dataGrid.SelectedItem == null)
            {
                dataGrid.SelectItem(viewModel.PersonCollection.First());
            }
            return false;
        });

Header Text, group header text, do not display some languages characters like Chinese, Thai, etc.

The root reason for this is the fact that the Skia APIs used to draw the text does not support automatic character fallback.

Workaround:

for header text:

<telerik:DataGridTextColumn.HeaderContentTemplate>
    <DataTemplate>
        <Label Text="your text"></Label>
    </DataTemplate>
</telerik:DataGridTextColumn.HeaderContentTemplate>

group header text

<telerik:RadDataGrid.GroupHeaderTemplate>
        <DataTemplate>
            <Label Text="{Binding Group.Key}"/>
        </DataTemplate>
</telerik:RadDataGrid.GroupHeaderTemplate>

column:

<telerik:DataGridTextColumn HeaderText="Name" >
    <telerik:DataGridTextColumn.CellContentTemplate>
        <DataTemplate>
            <Label Text="{Binding Name}"/>

On initial Refresh, all items are visible in the DataGrid

I navigate forward and then back (PopToRoot), the DataGrid appears empty, although the vertical scroll appears like there are items.

If I tap Refresh, items become visible, but only above the first fold.

If i resize the window vertically, items will appear and disappear depending on the height of the window. (see attached video)
