Display warning window in ASP.net C # web application

I want to display a warning message when the user clicks a button.

I have a " Signed " button when I click this button. I want to display the warning message “ Are you sure you want to continue? ” And the two buttons in this warning window “ Yes ” and “ No ”.

When I click "Yes", I want to execute the update function and click " No ". The warning should be closed and no changes to the current page.

Please can someone advise me how to do this?

You can use OnClientClick on the button for this. Add confirmation of return (); to him. It will create a javascript confirmation dialog before it fires the click event. If the user clicks no, he will not raise the OnClick event.

 OnClientClick="return confirm('Are you sure you want to continue?');"

So, added to the layout of your button, it will look like this:

 <asp:Button ID="Button5" runat="server" Text="Signed" Visible="False" onclick="Button5_Click" OnClientClick="return confirm('Are you sure you want to continue?');" />
