Drag drop related problem in MVVM

[Alpa]

hii,
I am trying to create an application in which I want to drag an item from a treeview and drop it in radgridview with MVVM. Here I used attached command behaviour. When these drag and drop feature applied in simple code behind way it works properly. In MVVM it doesnot work.

So please give me some solution for this problem with samples.

Thanks.

Hello Alpa,

Please, check this example in this blogpost - http://blogs.telerik.com/tsvyatkokonov/posts/10-12-15/using_commands_with_raddraganddropmanager_for_wpf_and_silverlight.aspx - although its in SL the same approach can be applied for WPF.

Let me know if this works for you.

Kind regards,

Hi Tsvyatko,
 
Thanks for reply. But you give me sample in silverlight 4 platform and i tried this code in my application. It didnt work and giving error because of the references used was from silverlight 4 dll's. I used CommandDragDropBehaviour class from sample in my WPF application and it didnt work.

So please give me solution of this problem.

Thanks
Alpa.

Thank you for your previous post. In the last post you give me a sample project in MVVM- Wpf. It work properly. But when I used that in my project in which I want to drag an item from a RadTreeView and drop it on a RadGridViw. My RadTreeView itemsource containes collection of Directory and i wanted to drag a folder or file from treeviewitem and drop it on datagrid column. And it didnt work.

So please give me some solution for these problem.
