RadTimeBar throws XamlParseException when current culture is arabic.

Workaround: Create a custom class that inherits from Telerik.Windows.Controls.TimeBar.SelectionThumb and explicitly sets the TitleFormatString property to your custom format string in the constructor. Edit the Template of the RadTimeBar control - find the SelectionThumb instance in the template and replace it with an instance of the CustomSelectionThumb class.

There is a fixed value of 16px set for the Height of the GroupHeader. Thus, when a FontSize bigger than 16px is set, the Text is cut off as the GroupHeader is not resized. The workaround is to predefine the GroupHeaderContentTemplateSelector and remove the fixed Height that is set through it. 

<telerik:GroupHeaderTemplateSelector x:Key="GroupHeaderContentTemplateSelector">
                <telerik:GroupHeaderTemplateSelector.HorizontalTemplate>
                    <DataTemplate>
                        <ContentPresenter Content="{Binding FormattedName}"  Margin="4" />
                    </DataTemplate>
                </telerik:GroupHeaderTemplateSelector.HorizontalTemplate>

                <telerik:GroupHeaderTemplateSelector.VerticalTemplate>
                    <DataTemplate> 
                            <ContentPresenter Content="{Binding FormattedName}" Margin="4" VerticalAlignment="Top">

If ExportDefaultStyles is set to true, the default styles are exported. If the user has set some settings in the ElementExportingToDocument handler, those are ignored.

Setting the property to false allows the custom setting to be applied, but the default ones are gone

TabControl's TabItems aren't properly updated on attempt to change the theme palette variation runtime until any of the items is selected. Check the following video - https://www.screencast.com/t/jMj0EZqFfy.

There are several possible workarounds which include:

  • Clearing all merged resource dictionaries and re-merging them
  • Increasing and decreasing the height of the MainWindow by 1 after loading the chosen palette to force the refresh

Properties bound with UpdateSourceTrigger=LostFocus in the content of LayoutControlTabGroupItem are not updated when changing the selected tab. The LostFocus event is fired after the data context of the corresponding element is removed and the issue appears.

To work this around subscribe to the PreviewMouseLeftButtonDown event of LayoutControlTabGroup and Focus the pressed tab (the new selection).

private void LayoutControlTabGroup_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
	var tabContainers = this.layoutTabGroup.ChildrenOfType<LayoutControlTabGroupItem>();
	var tabUndersMouse = tabContainers.FirstOrDefault(x => x.IsMouseOver);
	if (tabUndersMouse != null)
	{
		tabUndersMouse.Focus();
	}

I believe this is caused a bug in Telerik.Windows.Controls.VirtualGrid.Selection.CellSelectionHandler.ToggleSingleSelect() method:

    internal void ToggleSingleSelect()
    {
      if (this.owner.SelectionUnit != VirtualGridSelectionUnit.Cell && this.SelectedCells.Count <= 1)
        return;
      this.BeginSelection();
      VirtualGridCellInfo selectedCell = this.SelectedCells[0];
      this.DeselectAll();
      this.Select(selectedCell);
      this.EndSelection();
    }

If SelectionUnit = Cell but no cells are selected, the code still attempts to retrieve the first selected cell what causes an exception.

When you start navigating through the ribbon via the keytips or the arrow keys, and you get to a RadRibbonComboBox, this opens its drop down which contains RadRibbonComboBoxItems. 

In this case the keyboard navigation (using the arrows) of the RadRibbonComboBox doesn't work. This happens because the ribbon navigation implementation interfere with the combobox navigation.
