Hi all, I was just wondering if anyone can help me on this one. I have a page that dynamically adds controls to a page; its a survey form where the questions...and answers for multiple choice questions...are pulled from a database. Multiple choice questions are represented as RadioButtonLists. Each multiple choice question has an associated RequiredFieldValidator...and this is where my problem comes in. I tried to submit a page without selecting any option from the RadioButtonList, and indeed, the RFV's fired displaying the ErrorMessage. However, when I selected a value, the errormessage didn't go away as it normally would. Even more crazy, was that it seemed that some of the RFV's were validating some of the TextBoxes (for free response-type questions): I would type in a response and the ErrorMessage on one of the RadioButtonLists would disappear. I thought I must have been getting the ControlToValidate property messed up. This is what I did: I set the id of the RadioButtonList to whatever QuestionID was pulled in from the db i.e. myRadioButtonList.ID = (string)myRow["QuestionID"], where myRow is part of a RowCollection from a DataSet filled with the questions of the survey. Then, I set the ControlToValidate property of the RFV to myRadioButtonList.ID. Seems simple enough, right? After some tinkering around with trace and looking at the source, I was really confused b/c the RFV's were associated with their respective controls, yet it wasn't working as it should. Then, I set EnableClientSideScript = False on the RFV's, and everything worked as expected. Any ideas as to why the clientside script was messing up? Jake
