Hi , 
I  have a parent page from which i need to open a rad window where i save/update data. On saving/closing the rad window i need the rad grid in parent to refresh . Grid does not refresh until i do a post back on the page .
Following is the code i am using , 

In Master Page :
  <telerik:RadAjaxManager ID="mgr" runat="server" EnableAJAX="true" OnAjaxRequest="mgr_AjaxRequest"> 
            </telerik:RadAjaxManager>
            <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel2" runat="server" Skin="Vista"
                BackgroundPosition="Center" EnableEmbeddedSkins="true" />
            <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
            </asp:ContentPlaceHolder>
In Parent Page (.aspx)
 <script type="text/javascript">
            function GetRadWindow() {
                var oWindow = null;
                if (window.radWindow) oWindow = window.radWindow;
                else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
                return oWindow;
            }
            function refreshGrid() {                
                    $find("<%= RadAjaxManager.GetCurrent(this).ClientID %>").ajaxRequest("Rebind");  
                                      
            }      
</script>
In Parent Page (.cs)


 protected void Page_Load(object sender, EventArgs e)
    {
        #region AJAX Settings        
        RadAjaxManager mgr = RadAjaxManager.GetCurrent(Page);
        
        mgr.AjaxSettings.Clear();       
        mgr.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(mgr_AjaxRequest);
        mgr.AjaxSettings.AddAjaxSetting(btnSearch, pnlContent);
        mgr.AjaxSettings.AddAjaxSetting(btnSearch, rgcarrrier, (RadAjaxLoadingPanel)(this.Page.Master as MasterPage).FindControl("RadAjaxLoadingPanel2"));
        mgr.AjaxSettings.AddAjaxSetting(rgcarrrier, pnlContent);
        //mgr.AjaxSettings.AddAjaxSetting(RadWindowManager1, rgcarrrier);
        mgr.AjaxSettings.AddAjaxSetting(btnDelete, pnlContent);
        mgr.AjaxSettings.AddAjaxSetting(btnDelete, rgcarrrier, (RadAjaxLoadingPanel)(this.Page.Master as MasterPage).FindControl("RadAjaxLoadingPanel2"));
        mgr.AjaxSettings.AddAjaxSetting(rgcarrrier, rgcarrrier, (RadAjaxLoadingPanel)(this.Page.Master as MasterPage).FindControl("RadAjaxLoadingPanel2"));        
        #endregion


}




  protected void mgr_AjaxRequest(object sender, AjaxRequestEventArgs e)
    {
        if (e.Argument == "Rebind")
        {         
                
                rgcarrrier.MasterTableView.SortExpressions.Clear();
                rgcarrrier.MasterTableView.GroupByExpressions.Clear();
                rgcarrrier.Rebind();                           
           
            
        }
        
    }


In Rad Window (.aspx)
<script type="text/javascript">       
      
        function GetRadWindow() {
            var oWindow = null;
            if (window.radWindow) oWindow = window.radWindow;
            else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
            return oWindow;
        }
        function cancelAndClose() {
            var oWindow = GetRadWindow();
            oWindow.argument = null;
                        oWindow.close();
                        oWindow.BrowserWindow.refreshGrid();  
            return false;
        }    
          
    </script>

In Rad Window (.cs)
 protected void Page_Load(object sender, EventArgs e)
    {
        #region Ajax Settings
        RadAjaxManager mgr = RadAjaxManager.GetCurrent(Page);
        mgr.AjaxSettings.Clear();
        #endregion
}
 protected void btnClose_Click(object sender, EventArgs e)
    {
        ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "cancelAndClose();", true);
    }
    protected void btnSave_Click(object sender, EventArgs e)
    {
     (Page.IsValid)
        {
            //when save
            {
                ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "cancelAndClose();", true);
}
//when Update
{
 ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "cancelAndClose();", true);

Hello,

I have examined  your code and the mistake I noticed is that you clear the AJAX settings on each Page_Load. Please remove the code doing this and let me know whether this helps.

Grid not rebinding on Closing Rad Window

I have problem with radgrid refreshing, when i close the radwindow

my Gridpage aspx code looks like this
 <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest" EnableAJAX="true">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="RadGrid1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>

<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" AllowSorting="True"
            GridLines="None" ShowGroupPanel="True" Skin="Black" AutoGenerateColumns="False" Width="100%" AllowAutomaticInserts="false" AllowAutomaticUpdates="false">
            <ClientSettings AllowDragToGroup="True" AllowColumnsReorder="True" ReorderColumnsOnClient="True">
                <Scrolling AllowScroll="True" UseStaticHeaders="True" />
                <ClientEvents OnGridCreated="OnGridCreated" />
            </ClientSettings>

.......................
..................
<telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true"
            Skin="Black">
            <Windows>
                <telerik:RadWindow ID="UserListDialog" runat="server" Height="620px" Width="620px"
                    Left="150px" Top="50px" ReloadOnShow="true" ShowContentDuringLoad="false" Modal="true"
                    OnClientClose="closeRadWindow" />
            </Windows>
        </telerik:RadWindowManager>
protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)
        {
            if (e.Argument == "Rebind")
            {
                RadGrid1.MasterTableView.SortExpressions.Clear();
                RadGrid1.MasterTableView.GroupByExpressions.Clear();
                Presenter List = new Presenter(this);
                IList<FileAdmin> GridDta = List.PopulateGrid();
                RadGrid1.DataSource = GridDta;
                RadGrid1.Rebind();
            }
My javascript looks like this
function closeRadWindow()
                 {
                     $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");
                  
                }
       function refreshGrid()
                 {
                   $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");
                 
                 }
RadWindow aspx code Looks like this
javascript
 function CloseAndRebind() {
                        GetRadWindow().BrowserWindow.refreshGrid();
                        //GetRadWindow().close();
                    }
function GetRadWindow()
                     {
                        var oWindow = null;
                        if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog
                        else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; //IE (and Moz as well)
                        return oWindow;
                    }
Radwindow aspx.cs file looks like this
protected void buttonclick(object sender, EventArgs e)
{
if (result == true)
 {
ClientScript.RegisterStartupScript(Page.GetType(), "mykey1", "CloseAndRebind();", true);
 }
}
