Hi, I have a text box and DropDownList control and a validation control, When user entering a number in the text box, based on the entered number, the dropdrownlist value will change (document.getElementById('dnn_ctr-1_Register_ddReferral').value = document.getElementById("dnn_ctr-1_Register_txtReferral").value;) and the validation control will valify the dropdownlist if it's empty. I found there is a problem the server side Page.IsValid will always return false and ?ddReferral.selectValue is empty. But it works fine if I manually pick a item from the dropdownlist. What's the problem, do I need to chagne some value status after I use javascript to assign value to the dropdrownlist control? Please help. Many thanks.
