Hello Mehrdad,

Try the following code snippet.
C#:

protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
{
    RadComboBox combo = (RadComboBox)sender;
    RadTreeView tree = (RadTreeView)combo.FindControl("RadTreeView1");
    string value = tree.SelectedNode.Text;
}

Thanks,
Princy.

Hi Mehrdad,

Make sure that there is an item in the RadTreeView, which value is set to the value of the following expression: dt.Rows[0]["did"].ToString().

You could refer to the following help article for more information of how RadTreeView's items could be found: RadTreeView: Server-Side Programming Basics.
The following help article might be of help, too: RadComboBox: Accessing Controls Inside Templates.

I hope this helps.
