Strange Behavior in DevExpression Ajax [Resolved]

Good Evening My friends

I have been helping you , now its your turn to help :)

Due to Limitations in the Telerik, meaning that there is no nice Pop Control , and i want to create my own as i did in my previous article. I have used the DevExpress Popup Control and i have a Telerik Gridview inside it and i can nicely search for records and i can select the record from the Grid and i have a button that saves take an ID of that record like

        protected void btnselect_Click(object sender, EventArgs e)
        {
            String Ref =null;

            foreach (GridDataItem dataItem in grdactsandbills.MasterTableView.Items)
            {

                CheckBox chkselect = (CheckBox)dataItem.FindControl("chkselect");

                if (chkselect.Checked)
                {

                    Label lblReferenceNumberID = (Label)dataItem.FindControl("lblID");

                    Ref = lblReferenceNumberID.Text;
                }

            }
            txtreferencenumber.Text = Ref;
        }

this Button is in a PopupModal(DevExpress) , when this button is Clicked if assign that value to a textbox that is not part of the modal. and you can see i am doing it on the server side and the break point goes there and the watch shows that yes the value has been assigned to the textbox, but after i close the pop, the Textbox is empty. I am just buffled by this.



Thanks
