Control.AddHandler does not accept Telerik Routed event

[Kevin Hendriks]

Hello,

For my demo application I am trying to implement Drag and Drop functionality. But if I am using Silverlight Controls I can not use the following line of code
 (this line of code is from the treeview example DragAndDrop towards the textbox, From the Silverlight Q2 silverlight examples)

this

 

 

.target.AddHandler(RadDragAndDropManager.DropQueryEvent,

 

 

 

new EventHandler<DragDropQueryEventArgs>(TextBox_OnDropQuery));

 

First of because the Silverlight control has only 1 AddHandler methode wich is the following. Source
So I added true to it.
Argument 1: cannot convert from 'Telerik.Windows.RoutedEvent' to 'System.Windows.RoutedEvent' 

Are the examples not right? Or am I doing something terably wrong because I don't have those methods

Hello Kevin,

There is an AddHandler extension method and you need the Telerik.Windows namespace to see it.

Please include

using Telerik.Windows;

in your usings.

Hopefully this will work for you,

With that line of code it works. It might be usefull to include it in the documentation that you need that line.

I also figured out in the meanwhile that the following line also works without having the namespace.

 

RadDragAndDropManager

 

 

.AddDropInfoHandler(target, TextBox_OnDropInfo);

 

Thanks for the help.

Is AddHandler/RemoveHandler no longer available in Telerik.Windows? Also is there an alternative?
