Hi,

Best Regards

Hi Damien,

I had already been to that blog and use the validators.dll with the web.config changes... nothing happened...

This is the way i am using in the RowCommand of the gridview:

1    Protected Sub GridDetails_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridDetails.RowCommand
2      Page.Validate()
3      If e.CommandName = "Insert" AndAlso Page.IsValid() Then
4       ...
5       ...
6      End If
7    End Sub

This is my asp.net code for the customvalidator inside the gridview templatefield:

1    <FooterTemplate>
2        <asp:TextBox ID="txt_newVendorPC" runat="server" MaxLength="7" Columns="7" Text=""></asp:TextBox>
3        <asp:CustomValidator ID="cus_txt_newVendorPC" meta:resourcekey="cus_txt_newVendorPC" runat="server" ControlToValidate="txt_newVendorPC"
4             CssClass="alert" Display="Dynamic" ErrorMessage="Error Message Here!" OnServerValidate="cus_txt_newVendorPC_ServerValidate"
5             ValidationGroup="NewDetails" EnableClientScript="false">*</asp:CustomValidator>
6    </FooterTemplate>

Try getting rid of the ValidationGroup.  I found this post: http://weblogs.asp.net/lkempe/archive/2007/03/26/asp-net-ajax-and-asp-net-validators.aspx and the comment "Related to my previous comment: I have found out the reason why the Validation controls were not working in the UpdatePanel. It is because of the ValidationGroup property. I had had grouped my validators for the UpdatePanel by setting their ValidationGroup property to prevent them from validating their connected controls with the other validators on the page. However, it is surprising to see that there is no need to set the ValidationGroup property for controls if being placed in an UpdatePanel. Removing the ValidationGroup property solves the problem and the validators work fine."

Hi Damien,

Thanks for all your help.

I have fixed my head because it was what was really wrong eheheh

I never realized that the custom validator is not fired if the textbox is empty... so i added a requiredfieldvalidator and it started working...

Once again thank you, and sorry for wasting your precious time.

Best Regards,

Validation controls, which includes the BaseCompareValidator, BaseValidator, CompareValidator, CustomValidator, RangeValidator, RegularExpressionValidator, RequiredFieldValidator, and ValidationSummary control are not comapatible with UpdatePanel
