Linda,

>I have a drop down list on a web form that is bound to a business object. It was working correctly until I added a new item to the list with a blank display value and 0 as the control value. I did that in an override of the form's OnPreRender method, also setting the control's initial value to 0. Now when I pull up a record, the drop down value remains 0. Do I need to set the drop down list programmatically? Shouldn't that set once I get a new dataset?

I'm guessing your code in the OnPreRender() method is always getting fired. You may want to check a condition (possibly a session variable) to determine whether or not to set the initial value to zero.

Best Regards,
