ValidatorCalloutExtender not working as required

Question

User-1300886125 posted

Hi All,

 I am working on ValidatorCalloutExtender.

 I have tried using below code and while throwing error message in callout its just says * not the error message entered in RequiredField Validator.

 The textbox and validaion controls are inside GridVIew Footer template

 See the code below.

<FooterTemplate>
                                <asp:TextBox runat="server" ID="txtPONumberF"></asp:TextBox>
                                <asp:RequiredFieldValidator OnPreRender="Req_PreRender" ID="Req1" runat="server" Display="None" ControlToValidate="txtPONumberF" ErrorMessage="User Name is required." ToolTip="User Name is required." ValidationGroup="PO">*</asp:RequiredFieldValidator>
                                <ajaxToolKit:ValidatorCalloutExtender PopupPosition="BottomLeft" runat="server" TargetControlID="Req1" ID="Validator1">
                                </ajaxToolKit:ValidatorCalloutExtender>
                            </FooterTemplate>

 Please advice where it goes wrong

 Thanks in Advance

Instead of placing the '*' where you have placed, Assign it to 'Text' property of RequiredFieldValidator. Then ValidatorCallOutExtender will be working fine then, hopefully.

Few days ago i have same kind of problem to some extent. Validator Call Out was showing me the '*' as error message, even after changing the message.

then instead of refreshing the page, i cleaned my application then rebuilt it again and reran it. That worked for me..

Have you testes it in this way?

Hi pradeepkumar.gnanavel,

Please set the same ValidationGroup to the three controls.

Hi Zhi-Qiang Ni

 I have tried the option which u said even than it doesn't worked for me :(

 Is there any issue with Ajax dll versions. 

 Because one of the user is working with version 1.0 and i am working with version 3.0

 It works in 1.0 where as not in 3.0

 Thanks in Advance
