[ID] INT IDENTITY (1, 1) NOT NULL,
[ParentID] INT NULL,
[Name] TEXT NULL,
[Note] TEXT NULL,
PRIMARY KEY CLUSTERED ([ID] ASC)
);

3.code binded as folws
this.radTreeView1.DisplayMember = "Name";
this.radTreeView1.ParentMember = "ParentID";
this.radTreeView1.ChildMember = "ID";
this.radTreeView1.ValueMember = "ID";
radTreeView2.TreeViewElement.EditMode =TreeNodeEditMode.Text;

Hello Anoop,

Thank you for writing.

I replicated the exception you describe. The issue is logged to our Public Issue Tracker under ID 13880. To vote for it and subscribe to its status updates follow this link: http://www.telerik.com/support/pits.aspx#/public/winforms/13880. Please excuse us for the caused inconvenience. We will do our best to address the issue in a future release. I have updated your Telerik points for this report report.

One approach to avoid the exception is to create a custom RadTreeViewElement and override its EndEditCore method. This suggestion is implemented in the attached sample project. I hope you find it useful.

Let me know if you encounter further issues.
