drag and drop treeview items into a div container

[Rohan]

Hi,

I am using a RadTreeView. I saw the example regarding the dragging and dropping of treeview items in RadGrid. I want to drag the items from RadTreeView and drop it into a div.

Please assist me on this.


Thanks
Rohan

Hello Rohan,


In the demo it shows how to drop node in TextBox control ans setting the text value from client side (in dropOnHtmlElement method in demo). I hope this would shed some light on accomplishing your requirement.

Hi Shinu,

Thanks for your reply. Its done but another problem raised. When I drag and drop asp.net controls it works fine, but when I drop telerik controls it stops working. It gives following error: "Script controls may not be registered after PreRender."

Every item in the TreeView is basically a control like textbox, datepicker, dropdownlist etc. When I continue dropping  textboxes it works fine but as soon as I drop telerik datepicker and then any other other control it gives the above error.

I tried with OnInit, PreRender, OnLoad events but of no use. The error remains the same.


Please assist me...

Hello Rohan,

The example that you mention does exactly the same thing - checks the html element on which the drop occurs. You can check the dropOnHtmlElement function on this demo's code pages for reference.
