    Hi,

    do you have UserProfileDataSource control on the Page (you have EditProfileDataSource_Selecting which handles UserProfileDataSource.Selecting)? And is this EditProfileDataSource_Selecting method wired in aspx using OnSelecting="EditProfileDataSource_Selecting" or in code with Handles. Point is that not both are needed, they are optional ways to wire an event handler. if you already have OnSelecting="...", you don't need the Handles clause. If you have only Handles, check that it is set to handle correct control's event.
