Select current style (the style in the selection or under the caret) in styles gallery when selection or caret position is changed. 

If you set the RadNavigationView's IsPaneOpen property in XAML and start the application, the items are is not opened (the pane is collapsed). You can notice that IsPaneOpen property is set back to false, when the control gets loaded.

To work this around, subscribe to the Loaded event of the RadNavigationView instance and in the event handler, set the IsPaneOpen property.

private void RadNavigationView_Loaded(object sender, RoutedEventArgs e)
{
	this.radNavigationView.IsPaneOpen = true;
}

When you have rows grouped by null value and you try to move one of the rows to another group, a NullReferenceException is thrown.

This is reproducible only when DataView is used as ItemsSource of RadGridView.

To work this around, avoid using null values. Or avoid using DataView.

Hi,

Quick question on solution provided in the ticket : https://www.telerik.com/account/support-tickets/view-ticket/1464733 . 

It looks like we would need to show few SuggestedAction in vertical and others in horizontal orientation. Is it possible to set the orientation value from chat control ? 

Something like this ...

<ItemsPanelTemplate>

<VirtualizingStackPanel IsItemsHost="True" Orientation="{Binding RelativeSource={RelativeSource AncestorType={x:Type telerik:RadChat}},

Path=SuggestedActionOrientation}"/>

</ItemsPanelTemplate>

Select nested item in virtualized treeview with single selection mode.

Collapse its parent. Select item in the level of the parent. Expand the parent and notice two items are visually selected.

Expexted : only the last selected item with mouse should be visually selected.

Workaround:

While performing Cut operation inside RadDiagram, an exception in the MS Clipboard occurs with the following message:

System.Runtime.InteropServices.COMException: 'OpenClipboard Failed (Exception from HRESULT: 0x800401D0 (CLIPBRD_E_CANT_OPEN))'

For example:

some text // some comment

some text 2 // some comment 2

Specified argument was out of the range of valid values.
Parameter name: span

StackTrace:

Implement support for content controls (a.k.a. Structured document tags), which will allow inserting editing controls in the document:

- Rich Text
- Plain Text
- Check Box
- Combo Box
- Drop-down list
- Date picker

Do not confuse this feature with form fields support (see http://feedback.telerik.com/Project/143/Feedback/Details/146869 ).

The exception is thrown during "Put" operator execution.

If you select an item in RadMultiColumnComboBox and then replace the ItemsSource of the GridViewItemsSourceProvider, the selection in the autocompletebox part of the the control is not cleared. There are items that are still selected and are not presented in the ItemsSource.

To work this around, you can create a custom GridViewItemsSourceProvider and override its OnPropertyChanged method. When the ItemsSource is changed, you can reset the selection.

public class CustomGridViewItemsSourceProvider : GridViewItemsSourceProvider
{
	public RadMultiColumnComboBox Owner
	{
		get { return (RadMultiColumnComboBox)GetValue(OwnerProperty); }
		set { SetValue(OwnerProperty, value); }
	}
	
	public static readonly DependencyProperty OwnerProperty =
		DependencyProperty.Register(
			"Owner", 
			typeof(RadMultiColumnComboBox), 
			typeof(CustomGridViewItemsSourceProvider), 
			new PropertyMetadata(null));

	protected override void OnPropertyChanged(DependencyPropertyChangedEventArgs e)
	{
		base.OnPropertyChanged(e);
		if (e.Property.Name == "ItemsSource" && this.Owner != null)
		{
			this.Owner.SelectionBridge.ClearOwnerSelection();
		}
	}
}

 <telerik:RadMultiColumnComboBox.ItemsSourceProvider>
                <local:CustomGridViewItemsSourceProvider Owner="{Binding ElementName=mccb}" />
            </telerik:RadMultiColumnComboBox.ItemsSourceProvider>
