RAD Combo box Validation

[Edward]

I have few RAD combo boxes in my form view. I'm using ObjectDataSource for the RAD Combo boxes where "EnableAutomaticLoadOnDemand" is used. Other RadComboBoxes are populated on load with hand coded data source and data bind.

I'm using "EmptyMessage" and "Allow Custom Text" properties to get water mark empty message for all of them.

While entering the details or while submitting the form I want to validate that the RAD combo boxes should have selected item, selected text and selected value. I don’t want any custom text to get submitted. I just want to use the "Allow Custom Text" property to get water mark empty message and to do item request where "EnableAutomaticLoadOnDemand is used.

 Please give me example to validate in client side or server side or both.
