TextChanged
The TextChanged fires when you change the selected item. It will fire automatically if the **AutoPostBack="True".**The event fires after the SelectedIndexChanged server event.
The event handler receives two parameters:
-
The instance of the listbox firing the event
-
An event arguments parameter containing no methods
C#
protected void RadListBox1_TextChanged(object sender, EventArgs e)
{
TextBox.Text = RadListBox1.SelectedItem.Text;
}
