Question

I am using Page.Isvalid function in my web page.I have two buttons in my web page namely “save” and “generate”.when i click the save button the validation summary will be invoked in which all the validations in this page will be shown.

Now I dont want to show a particular validation message for the “Save” button, but the same validation message should be shown specifically to “generate” button in the same page.

But i am using Page.Isvalid in the “save” button click which is displaying all the validation messages in the page.

Any help would be deeply appreciated.Thanks

You can use ValidationGroup(s) to do this.

<form id="form1" runat="server">
   <div>
       <asp:TextBox ID="TextBox1" runat="server" />
       <asp:RequiredFieldValidator ID="R1" runat="server" 
            ErrorMessage="*" 
            ValidationGroup="GenerateOnly"
            ControlToValidate="TextBox1" />
       <asp:Button ID="Generate" runat="server" Text="Generate"
            ValidationGroup="GenerateOnly" />
       <asp:Button ID="Save" runat="server" Text="Save" />
   </div>
</form>

This example triggers the validator if Generate is clicked, but not when Save is clicked, and also works when calling Page.IsValid in the buttons onclick function.
