After successfully solving all the previous issue now im stuck on the final line of code.That is from the master page :

C#

public bool CheckErrors()
{
    //Page x=new System.Web.UI.Page();
    ValidationSummary sum= new ValidationSummary();
    Page.Validate(sum.ValidationGroup);
    if (!Page.IsValid)
    {

        //this.EnsureChildControls();
        UpdatePanel update = new UpdatePanel();
        update.ID = "update";
        update.UpdateMode = UpdatePanelUpdateMode.Conditional;
        update.Update();

        modalPopupEx.Show();//error is in this line
        return false;
    }
    return true;
}

Error say Object reference not set to an instance of an object.This is the last line of code to display the popup...Help needed

Thanks

Thanks I have solved it.

It should have been

public bool CheckErrors()
{
//Page x=new System.Web.UI.Page();
ValidationSummary sum= new ValidationSummary();
Page.Validate(sum.ValidationGroup);
if (!Page.IsValid)
{

//this.EnsureChildControls();
UpdatePanel update = new UpdatePanel();
update.ID = "update";
update.UpdateMode = UpdatePanelUpdateMode.Conditional;
update.Update();
modalPopupEx = new AjaxControlToolkit.ModalPopupExtender();

modalPopupEx.Show();
return false;
}
return true;
}
Thank you all for your time.
