Rebind of RadGrid Reopens up a RadWindow with RadContextMenu

[Pat Huesers]

I have a page that has a RadGrid with a Context Menu on it.   I am using the context menu to fire open a RadWindow that is hosting another aspx page with a RadProgressArea completing a long running process.   Once the job is finished I have some JS in a placeholder that I make visable to Rebind the radgrid and then close the RadWindow.

Everything works fine except if I rebind the RadGrid the RadWindow reopens back up.   What am I doing wrong?



Here is the main aspx page - stripped down to be simple.

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="PartInventory.ascx.vb" Inherits="UserControls_PartInventory" %>

            function RowContextMenu(sender, eventArgs) {

                var menu = $find("<%=RadMenu1.ClientID %>");
                var evt = eventArgs.get_domEvent();

                if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {
                    return;
                }
                var index = eventArgs.get_itemIndexHierarchical();
                document.getElementById("radGridClickedRowIndex").value = index;

                sender.get_masterTableView().selectItem(sender.get_masterTableView().get_dataItems()[index].get_element(), true);
                menu.show(evt);
                evt.cancelBubble = true;
                evt.returnValue = false;

                if (evt.stopPropagation) {
                    evt.stopPropagation();
                    evt.preventDefault();

                }
            }

            function refreshGrid() {
                var masterTable = $find("<%=rgInventoryEdit.ClientID%>").get_masterTableView();
                masterTable.rebind();
            }

Hello Pat,

The issue stems from the fact that the VisibleOnPageLoad property of the RadWindow is used. It will cause it to reopen with every page postback. In order to open the window from the server I advise that you examine the following help article: http://www.telerik.com/help/aspnet-ajax/window-troubleshooting-opening-from-server.html. It will show you a JavaScript registration approach that will not have this shortcoming, or you could use the other suggestion and disable the ViewState of the control.

You may also find useful this help article on the different ways to open a RadWindow: http://www.telerik.com/help/aspnet-ajax/window-programming-opening.html. If possible for your scenario, you could use only the client-side click on the menu to show the RadWindow. This will spare an unnecessary postback if it has no other purpose than to show the RadWindow.
