Hello,

At the moment I am using this LINQ query in C# to check all items but I am wanting to do the same in javascript.

I tried the following 3 thigns in javascript and in IE F12 tools I tried to find & 'check' the 'Check All' to but that did not seemed to be checking all items (Not sure)

not sure the 2nd attempt was in the right direction. I am getting the correct id of radCombobox using sender.get_id();

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">

                     <UpdatedControls>

                         <telerik:AjaxUpdatedControl ControlID="RadSplitter2" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelCssClass="" />

                     </UpdatedControls>

             </telerik:AjaxSetting>

         </AjaxSettings>

 </telerik:RadAjaxManager>

function OnClientNodeClicking(sender, args) { 
    var currentLoadingPanel = $find("<%=RadAjaxLoadingPanel1.ClientID %>");

    currentLoadingPanel.visibility = true;

     var url = args.get_node().get_value(); // get value

     var rd = $find("<%=Main.ClientID%>");

     rd.set_contentUrl(url); // Set the url

     args.set_cancel(true); // Cancell the event

    currentLoadingPanel.visibility = false;

}

<asp:Button ID="uxPrint" runat="server" ToolTip="Save/Print form" onclick="uxPrint_Click" UseSubmitBehavior="false"/>

There is no javascript on this button (other than what goes on with telerik's AJAX system);
 
The codebehind Starts with:

protected void uxPrint_Click(object sender, EventArgs e) { 
  RadGrid rgMain = Page.FindControl("rgMain") as RadGrid;

    rgMain.ExportSettings.OpenInNewWindow = true;

    rgMain.ExportSettings.Pdf.Title = uxEmployeeNameField.Text + " - " + uxCategoryField.Text; //...

    rgMain.ExportSettings.Pdf.PageTitle = rgMain.ExportSettings.Pdf.Title;

    rgMain.ExportSettings.Pdf.PageLeftMargin = Unit.Parse("10mm");

 . . .

//and finishes with:

    rgMain.MasterTableView.ExportToPdf();
