When two columns in two separate column groups have the same name and they belong two separate column groups, the column group names of the parent column groups can be appended to the display content of the GridViewGroupPanelCells.

For example, the duplicate Code columns in the attached image should have content "PG Code" and "VENUE Code" respectively.

Every KeyTipControl is placed inside a Popup. Expose properties which could control the Popup position.

Currently, the PanZoomBar is not themed across the themes. Consider improving this by applying different colors to the Thumbs based on the applied theme.

Currently when you highlight a row in the child GridView, the ParentRow becomes highlighted. It would be really nice to have an option so that the ParentRow would be selected when a row in the child GridView is selected. This should work recursively selecting the ParentRow all the way up the hierarchy.

I've written a workaround, but it isn't pretty.

Please add this functionality. :)


My case involves a three tier hierarchical GridView (each in single select mode). If I select a row in a third tier GridView, then I want its ParentRow to become selected on the second tier and the second tier's ParentRow to become selected on the first tier. Hopefully that makes sense.

Expose an event that allows you to cancel the navigation to a folder. For example, if you enter an address in the breadcrumb, click the back button, or select a directory in the navigation tree, then you should be able to cancel the navigation.

This can be done via a new event that have a Cancel property in its arguments, for example.

The naming shown here is not mandatory.

A possible solution could be to expose a HostCreated event so we can get the Window and set its AllowTransparency and WindowStyle property.

It would be nice to have some additional public properties and commands for ExplorerControl.  For example:

  • Boolean properties to show/hide the first two rows (containing the breadcrumbs, new folder button, layout combo box, etc.).
  • Search command or public SearchText property.
  • Cancellable OnNavigating event.
  • Navigation tree "RootDirectory" property, which would replace the top-level "This PC" node.

Thanks for your consideration!

Release LIB 2019.2.520 (05/20/2019)


I've created buttons that are bound to FileDialogCommands for sending commands to an ExplorerControl, as shown here:


Everything works when the ExplorerControl is visible.  However, if the ExplorerControl's Visibility is set to Collapsed (which I need based on a condition), the Command bindings on the buttons throw the below error:

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.Windows.Controls.FileDialogs.ExplorerControl.CanExecuteHelper(Object sender)


The UserControl that hosts the ExplorerControl is being imported through MEF.  I don't know if that's a factor.

Either way, it looks like a null check might be needed for the InternalViewModel property.

When you resize (but only decreasing size) the control, the position and size of the Marker indicator is not updated. 

This is reproducible with RadVerticalLinearGauge and VerticalLinearScale. When the RelativeHeight of the scale is set to 1 and the RelativeY is set to 0.

As a work around you can avoid setting the RelativeHeight and RelativeY properties of VerticalLinearScale.

When the IsHidden property of a RadPane within a ToolWindow is set to True and then to false in quick succession, the ToolWindow is not shown. 

As a workaround, you can disable the animation of the ToolWindow:
<Style TargetType="telerik:ToolWindow">
<Setter Property="telerik:AnimationManager.IsAnimationEnabled" Value="False" />

The above style need to be placed in the resources of the App.xaml in order to take effect on the ToolWindows, since they are displayed in a separated visual tree.

When the TextSearchMode is set to Contains, setting the Text property of the RadComboBox, the first partially match element will be returned. The expected result is the full match (if exist) element to be set first.
