implement dragdrop in treeviewadv

[Zheng Lin]

Hi,
I am using syncfusion version 4.4 TreeViewAdv control on window form in a C# application.
I followed the sample code included in the essential suites getstarted guide to implement the dragdrop effect. However, I come across out of bound exception right after I click on some node on the tree and start to drag it. The exception goes as follows:

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:





When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.


Can anyone tell me what I missed here?

Thanks

Hi Zheng,

Thanks for your interest in Syncfusion products.

This is a known issue in 4.4 version. We have fixed this issue internally. Could you please create a Direct-trac incident with subject line "TreeviewAdv - Dragging Child node throws Exception - F60085". We will send you the bug fix details through the Direct-trac System.

Best regards,
