Question

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,

Answer 1

Try using the SelectionChangeCommitted event.

From MSDN documentation:

SelectionChangeCommitted is raised only when the user changes the
combo box selection. Do not use SelectedIndexChanged or
SelectedValueChanged to capture user changes, because those events are
also raised when the selection changes programmatically.
