Kevin,

Thanks for the reply and tip. I will add the code to my subclassed control.

This is a good example of code that should be placed on a "Known Issues Page" somewhere. Do you plan on adding this kind of page to your company website?

public override void StateChangeHandler(OakLeaf.MM.Main.Business.mmBaseBusinessObject bizObj, OakLeaf.MM.Main.Business.mmBusinessStateChangeEventArgs e)

To do this, create a new method at the form level that checks the current state and if it's Added, binds the control. For example:
>
>

private void Orders_StateChange(mmBaseBusinessObject bizObj, mmBusinessStateChangeEventArgs e)
>{
>	if (e.State == mmBusinessState.Added)
>	{
>		this.BindControl(this.cboShippers, this.cboShippers.BindingValueSource,
>			this.cboShippers.BindingValueSourceMember);
>	}
>}

>And then add code to the form's Load that registers the handler method with the business object's StateChange event. For example:
>
>

this.oOrder.StateChange += new mmBusinessStateChangeDelegate(this.Orders_StateChange);
