Is it possible to add scroll bars to the mail merge field drop-down box? Our mail merge source can have 15+ fields in it. When a user is editing RTB content and clicks the Insert Merge Field button the list pops up but half the fields are not visible and there's no way to scroll the list. Does this require handling the insert command and customizing the drop-down? Even turning on CanVerticallyScroll doesn't seem to help.

No matter which value I use for TabStripPlacement, it's drawn at the top.  Why?

Code:

After using the Radpane, the selected item is not having the style applied. If RadTreeView alone is used (without having radpane), the selected item in the radtreeview is having the style SelectionUnfocusedVisual which is working properly (i.e), Selected Item gets Highlighted. How to make the selected item in the radtreeview to have a style applied (or) to highlight the radtreeview selected item when a radpane is used?. Thanks.

I posted a thread two days ago about a problem I was having with e.Handled in a RadDocking.Close event.  After looking at the code, I moved the logic to the PreviewClose event; however the result is the same.  I am attempting to close all the panes in a RadPaneGroup inside the DocumentHost.   I have tried...

• RadPaneGroup.HideAllPanes(), but the panes remain visible.  After the call I can close all but the first pane indiviually using the close button on each tab.  If I drag the last remaining pane off the tabstrip it disappears.
• Any direct manipulation of the RadPaneGroup.Items, whether a call to Clear(), Remove(pane), RemoveAt(index) causes an n "Object reference not set to an instance of an object." exception after exiting the handler with e.Handled set to true.

All of this happens in 2012.2.620 and did not happen in 2012.2.607.  Please let me know if there is a way to achieve this functionality without having to revert to using the previous version.

Thanks in advance, Steve

Hello,

I already implemented some drag and drop behaviors in my application. To do so, I create a DragVisual in the OnDragInitialize event (registered via DragDropManager.AddDragInitializeHandler), and I give it a DataContext (a Content actually) and a ContentTemplate. Then I can have a nice preview of the data being dragged that I can template as I wish and that will follow the mouse cursor.
This work perfectly when I'm dragging data from my app, to my app.

Now I am willing to be able to drag files, from the windows explorer, to a specific control of my application. I would like to create a DragVisual in the same way, when the mouse cursor enters one of the windows of my application (and destroy it if the mouse cursor leaves the window, but this is another problem).

The problem is that when the drag starts from another application, OnDragInitialize is not invoked (which makes perfectly sense). But how can I achieve to create a DragVisual in this context? None of the other drag'n'drop-related events have a DragVisual in their EventArgs.

Thanks

Hi,

we crearte the Shapes like this:


then we bin the Shapes to the toolbox


For example we habe a simple RectangleShape. With a cutom Tab in EditMode we select a Employee and now we want to edit the RectangleShape. Is it possible to change the view of the RectangleShape during runtim, for example see attached files.

Thanks a lot
Best Regards

I am trying to make it so my user can change the theme at runtime in my project. It works fine for most of the controls, however the TabControl as well as the MenuItems and Menus do not change. Is there something I am missing? I looked at the quickstart samples but I don't have that dll in my binaries folder. Is that intentional?

I have a RadPivotGrid setup as follows which gives the error stated in the title "The attachable property 'DataProvider' was not found in type 'RadPivotGrid'"
            <pivot:RadPivotGrid>
                <pivot:RadPivotGrid.DataProvider>
                    <pivot:LocalDataSourceProvider ItemsSource="{Binding Path=Events2}"/>
                </pivot:RadPivotGrid.DataProvider>
            </pivot:RadPivotGrid>

This is in Visual Studio 2013 Express with Telerik Q1 2014 WPF 4.5.

I also made sure I have the following references (and some extra):
Telerik.Pivot.Core
Telerik.Windows.Controls.Pivot
Telerik.Windows.Controls
System.Runtime.Serialization

It does compile but no interface is shown. Events is a list of standard objects with properties. If all works well should I assume that it just prints a flat grid with the above definition?
