Question

I’m filling a combobox with the datasource property in a c# winform app. In the other hand, I’m firing up an action with the SelectedIndexChanged of the same combo. The problem is that whenever the combo is filled with datasource the SelectedIndexChanged is called and I just want this event to be called when the user in fact does a selection.
Is there a way to avoid calling this event when filling the combo?

This is some of my code

//Filling the combo with some data
combo_cliente.DataSource = clientes;
combo_cliente.DisplayMember = "NomComp";
combo_cliente.ValueMember = "IDPersona";

private void combo_cliente_SelectedIndexChanged(object sender, EventArgs e)
{
    // Here is the action to be triggered when user perfoms a selection
}

Thanks

Maybe unsubscribe and then subscribe again:

combo_cliente.SelectedIndexChanged -= combo_cliente_SelectedIndexChanged;
combo_cliente.DataSource = clientes;
combo_cliente.SelectedIndexChanged += combo_cliente_SelectedIndexChanged;
