The search box TextBox element used with the search-as-you-type feature is not focused when you press the Tab key. This happens because the search box is excluded from the tab order (IsTabStop=False).

Use the ChildrenOfType extension method to get the TextBox element and set its IsTabStop to True.

private void gridView_Loaded(object sender, RoutedEventArgs e)
{
	var searchBox = this.gridView.ChildrenOfType<TextBox>().FirstOrDefault(x => x.Name == "PART_SearchAsYouTypeTextBox");
	searchBox.IsTabStop = true;
}

The ItemsControl that holds the control panel of RadGridView should not be included in the tab order. Its IsTabStop property should be False. Only the items inside of it should be included in the tab order.

To work this around, use the ChildrenOfType extension method to get the ItemsControl and set its IsTabStop property. Optionally, you can exclude also the ControlPanelItemControl elements from the tab order.

private void gridView_Loaded(object sender, RoutedEventArgs e)
{
	var controlPanel = this.gridView.ChildrenOfType<ItemsControl>().FirstOrDefault(x => x.Name == "PART_ControlPanelItemsControl");
	controlPanel.IsTabStop = false;
}

When the ItemsSource is not set: ArgumentOutOfRangeException is thrown

When the ItemsSource is set to an empty collection: DivideByZeroException is thrown

Hi Telerik-Team,

When creating a new item in the GridView by either mouse or insert button the row is not selected or highlighted.

I guess this is a bug, since a cell in the new row has focus but not the row.

Best regards,

The designer throws an error when the default style of a control which has a RadSplitButton/RadDropDownButton in its control template is extracted in a ResourceDictionary and then merged in App.xaml. There must be a custom style which is based on the extracted one to reproduce the error. This behavior is only present in 2019 R3.

The error is "This feature requires service 'Microsoft.Windows.Design.Services.ValueTranslationService' to be present, but it could not be located."

When adding a new row and we click inside a DropDownContent of a DropDown control, the RadGridView loses focus. This way RowValidating event is called which is not expected.

Bind a grid to a DataView

Start editing and change the values of a few cells.

Press Escape twice to cancel the edit of the entire row.

Expected: the values return to the old values

Actual: the values remain the last entered ones
