I just upgraded the AjaxControlToolkit.dll from 4.0.5.0731 to 4.1.7.0725 and noticed an important change of behavior:
Both CompareValidator and MaskedEditValidator are always on! Even if I specified IsValidEmpty=”true”. If I TAB through a field and not type anything in it, it is treated as if it was typed into, and the validation fails.
Is there a way to make the check optional, as it was in the previous version?
Help most appreciated.
