I have a control that has a look up lists of status values. It is bound to a ProjectEntity that has a foreign key value for StatusId. The problem is that status can be null. The issue I'm running into is that the webform goes into edit mode displaying the combobox but I get an error message that states selected value does not exist in the dropdown box. How can I bind this null value to a lookup?

Thanks

I think you should manually add an Item to the dropdownlist (eg. "--N/A--" with a value of 0). And you select this item in case of null value.
