ASP.NET Button OnClientClick Confirm Dialog

Hello friends,

I'm looking at this example from W3Schools:  

http://www.w3schools.com/aspnet/showaspx.asp?filename=demo_prop_webcontrol_button_onclientclick

The problem I see here is that the server-side function is invoked whether or not the client-side function returned true.  It's not really doing a real Cancel.  How do I modify this so that the server-side function is only invoked IF the client-side function returns true.  If the client-side function returns false, then the server-side function should not be invoked.

Thanks so much for your assistance.

Jazon

Hi,
I have did it in GridView for Delete Confirmation. Check it out.

You can do this by following way..
First you need to add below code in your aspx page

<script type="text/javascript">
        function ConfirmationBox(username) {

            var result = confirm('Are you sure you want to delete ' + username + ' Details?');
            if (result) {

                return true;
            }
            else {
                return false;
            }
        }
    </script>

Open in new window


Next just add following code in your page load..
btnDelete.Attributes.Add("onclick", "javascript:return ConfirmationBox('" + username + "')");

Open in new window

Just add 'return' to the code. From your link:
was:
asp:Button OnClick="btClick1" OnClientClick="btClick2()"
Text="Click Me" runat="server" />
should be
asp:Button OnClick="btClick1" OnClientClick="return btClick2()"
Text="Click Me" runat="server" />

or even simply
OnClientClick="return confirm('Are you sure?');"
