are you validating validation control on server side also?

Prasad_Kulkarni 24-Aug-12 2:39am

Can you post specific validation message and its code??

@bhagirathimfs, May i know why you have edited that question after 5 years of a posted date ?

They didn't - it's a bug (already reported) in the way updates are reported. bhagirathimfs updated the question back in 2012 but kundan saw has now posted another solution to resurrect the post :sigh:

You are keeping Text property blank for required field validator so its showing twice.

Hence Put an star (*) on Text property of every RequiredFieldValidator

Just like below:-

XML

<asp:RequiredFieldValidator ID="reqfvtxtregConfpw" runat="server" ControlToValidate="txtregConfpw"
ErrorMessage="Required Confirm Password" Display="Dynamic" ValidationGroup="Reg" Text="*"></asp:RequiredFieldValidator>
