Hi telerik ,
I have one strange problem I am trying to drop grid view data in another grid view , first of all I did not find any suitable example where you bound grid with RIA domain data source and we can check it.
Right now what happening with me I was not able to refresh second grid after drop , or you can say this line of code is not working for me
xxTable1DataSource.Clear();

xxTable1DataSource.Load();

I really appreciate if you can help me about drag and drop using wcf ria datasource , please find the example code here I used.

Thanks,
Shakti

Hello Shakti SIngh Dulawat,

I have prepared small project demonstrating how to enable drag drop operations in your scenario. Please have a look at the attachment, containing the project as well as database with dummy data.
