Comobox event SelectedValueChanged

Question

Hi,
i have simple question may be someone asked it before me but i could not find it.Let say i have datatable that has some data from the database and i want to bind it to a combobox i use standart code like this

 comboBox1.BeginUpdate( );
 comboBox1.ValueMember = "id";
 comboBox1.DisplayMember = "name";
 comboBox1.DataSource = dt;
 comboBox1.EndUpdate( );

The problem is during this binding the event SelectedValueChanged is fired.The problem is that rebind combo several times when outher values change and every time i must do sometihn like this

 comboBox1.SelectedIndexChanged -= new System.EventHandler( this.comboBox1_SelectedValueChanged );

my question is there a smarter way to skip the event when i comes from databinding not from user input.The problem is that i want to do it some how globaly in my control that inherits combobox and not to do it everytime in every from Best Regards,
