I created a custom lookup combobox contral based on mmcombobox. It has a browsable property called "Lookupcode" which is the key used to return an entitylist for the combobox to bind to. I set the lookupkey property to what I want as the key.

When I place the control on a form and run, it does not appear that the lookupkey property gets an assigned value until after the constructor fires. I see where the InitializeComponent method of the form assigns the value to the property.

The combobox makes a call to the lookup BO to get an entitylist for the object and bind the control to the results. Currently, I have the call in the BindingContextChanged method but don't think it is the best place since binding the control to the results causes the method to fire again. What is the best place to put code like this that needs to fire after the control's constructor?
