For now I put an empty string like this "" on change event but that's not the proper form. On the other, hand how can I create an autopostback when I change values in one of the dropdown list, I mean a "refresh" when I upload the form to SharePoint. The idea is when the form is uploaded on the web I want to make another refresh when I change a value in one of the dropdownlist. Im' Coding with C# on Visual Studio For Applications
