                </div>

            </div>

            </div>
        </div>





    <div class="footer">

        CopyRight@Fiji National University</div>
    </form>
</body>
</html>

then in my master code behind i have:

public partial class SiteMaster : System.Web.UI.MasterPage
{

    protected void Page_Load(object sender, EventArgs e)
    {
        if(!HttpContext.Current.User.Identity.IsAuthenticated )

        {
            NavigationMenu.Items.Clear();
        }
    }

   public String ValidationGroup
    {
        set
        { valSummary.ValidationGroup = value; }
    }

    public bool CheckErrors()
    {
        Page.Validate(valSummary.ValidationGroup);
        if (!Page.IsValid)
        {
                update.Update();
                modalPopupEx.Show();
            return false;
        }
        return true;
    }

}

Then from another web form i trying to validate a textbox like this:

protected SiteMaster PageMaster
   {
       get
       {
           return this.Master as SiteMaster;
           //return this.Site as SiteMaster;
       }
   }
   protected void ImageButton2_Click(object sender, ImageClickEventArgs e)
   {
       //SiteMaster master = (SiteMaster)this.Master;
       if (PageMaster.CheckErrors())
       {

}

The problem is that the validations only occurs at the server side and no popup appears at the client end...Where do im doing something wrong and how can i show up the popup

Thanks
