I'm hoping somewhere here on the forums can help me as I've searched all over (on the forums) and in the documentation and examples and are coming up dry. Right now I'm building a system in where the end-user can take a product (or products) from a RadGridView and drag them over to a RadTreeView which contains Categories and onto a RadTreeViewItem. 

The entire system as it stands works perfectly for a single GridViewItem but I need to be able to support multiple items. Unfortunately I have not been able to find any solution in the demos or on the forums (most posts are either WinForm related or use the deprecated RadDragDropManager). If anyone can shed some line on how I can handle multiple items with the newer DragDropManager that would be great.

Current code is attached.

I am trying to create a DependencyProperty to persist the layout of my docking panes.  I am running into an issue when I float the docking pane, close the window and then call LoadLayout when opening the window again.  I have narrowed the issue down to which event I catch to save the layout.  If I catch the RadDocking unloaded event the xml produced in the save layout doesn't work like I would like it too.  If I catch the closed event on the Window then life is good and the floating window restores correctly (because this is an attached property this is not a valid work around).  The difference in the xml is the IsInOpenWindow attribute, when I save from the window closed this value is false and when I save from the RadDocking unloaded event the value is true.  I understand why this occurs, the closed event occurs before the RadDocking unloaded event.  My question is when is the best time(what is the best event to catch) to save the layout of the docking windows without requiring intervention from the user?

Thanks.

I am willing to provide code if that would help.

Hi,

I followed the instructions on the Telerik web page 'http://www.telerik.com/help/wpf/coded-ui-support.html' and copied the assembly Telerik.VisualStudio.TestTools.UITest.Extension.ExtensionsCore into the folder C:\Program Files (x86)\Common Files\Microsoft Shared\VSTT\11.0\UITestExtensionPackages. Then installed the assembley into GAC.

I am using VS 2012. When I try to use Coded UI Test Builder, it terminates with the following exception.

Application: CodedUITestBuilder.exe

If I remove the assembly from the folder, Coded UI Test Builder lauches without error but it does not record actions on Telerik controls as expected.

Is there anything I can do to avoid this error?

Thank you,

Hi,

I'm using the DragDropManager to allow dragging from one RadListBox to another RadListBox. But I need to identify the exact RadListBoxItem on the target list box where the item was dropped onto.

I was hoping to achieve this by using this style for the target list box:

And applied this to the list box:

Note: I did not set AllowDrop=true on the list box itself (I tried it, but I made no difference).

But my DropHandler never returned the list box item, instead I was getting the list box itself.

BTW
Is there a way to highlight the list box item below the the mouse while dragging an item over it?

Thanks,
Thorsten

            Thanks in Advance.

I would like to replace the default "error" image that is used to denote and invalid column (see attached image).  What's the best way to do so?

                    <WrapPanel Orientation="Vertical">
                        <telerik:RadRibbonButton Text="RadRibbonButton" Height="5" VerticalAlignment="Top"/>

Hi,
I am using RadTreeList View, when i set EnableRowVirtualization= "False" every time i am getting one extra row after clicking the Expandar.
I am not understanding why RowVirtulization is adding an Extra Row and how to get Rid of this Issue. 

Hi,

First of all, thank you for the wonderful products and controls. I am getting familiarized with the code and everything has been going smoothly so far.

My question is, is it possible to add elements to RadChart ChartArea DataSeries in an asynchronous way, so that the main UI would not be blocked during setting the variable?

Thank you!
