The server-side OnEntryRemoved event occurs when an entry is removed from the entry area, causing a postback. The postback is triggered when the dropdown is closed. To close the dropdown when a node is selected, you can set DropDownSettings-CloseDropDownOnSelection="true".

The event handler receives two parameters:

  1. The instance of the DropDownTree firing the event

  2. An event argument parameter that contains the following property:

    • Entry - returns the entry that has just being removed from the input.

protected void RadDropDownTree1_EntryRemoved(object sender, DropDownTreeEntryEventArgs e)
    Label1.Text = e.Entry.Text + " was removed.";

Protected Sub RadDropDownTree1_EntryRemoved(sender As Object, e As DropDownTreeEntryEventArgs)
    Label1.Text = e.Entry.Text + " was removed."
End Sub
