<asp:Button runat=server ID=btnUserDelete Text=Delete CssClass=GreenLightButton

                           OnClick=BtnUserDelete_Click

                           OnClientClick=return UserDeleteConfirmation(); 

 meta:resourcekey=BtnUserDeleteResource1 />

I have tried:

function UserDeleteConfirmation() {

        if (confirm(Are you sure you want to delete this user?))

            return true;

        else

            return false;

}

and

function UserDeleteConfirmation() {

    if (confirm(Are you sure you want to delete this user?)) {

            __doPostBack(btnUserDelete, '');

    }



    return false;

 }

And none of them works.

Try this:

<asp:Button runat=server ID=btnUserDelete Text=Delete CssClass=GreenLightButton

                       OnClick=BtnUserDelete_Click

                       OnClientClick=if ( ! UserDeleteConfirmation()) return false; 

 meta:resourcekey=BtnUserDeleteResource1 />

This way the return is only executed when the user clicks cancel and not when he clicks ok.

By the way, you can shorten the UserDeleteConfirmation function to:

function UserDeleteConfirmation() {

    return confirm(Are you sure you want to delete this user?);

}
