    I'm experiencing an issue that was that is similar to the issue found at I have a radgrid that I'm binding to JSON results on the client-side. Regardless of the number of records, the record count always reads 11 items in 2 pages.

    I've followed all of the recommendations in the previous issue, but I don't think there was ever any actual resolution to that problem.

    Here's what I have, and a screenshot to show the symptoms:


    <div class="tab-pane row in active" id="selected">
      <div class="col-md-12">
        <telerik:RadAjaxLoadingPanel runat="server" Skin="Default" ID="loadPanel" />
        <sg:IPGrid runat="server" ID="rgSelected">
          <MasterTableView CommandItemDisplay="Top" AutoGenerateColumns="false"  AllowPaging="True">
            <PagerStyle Mode="NextPrevAndNumeric" AlwaysVisible="True" Position="Bottom" />
              <telerik:GridTemplateColumn HeaderStyle-Width="50px">
                  <asp:Button runat="server" ID="Button1" Text="Add" CssClass="btn btn-sm" />
              <telerik:GridBoundColumn DataField="Title" HeaderText="Title" HeaderStyle-Width="450px" />
              <telerik:GridBoundColumn DataField="AssignedTo" HeaderText="Assigned To" />
              <telerik:GridBoundColumn DataField="HotfixOwner" HeaderText ="Hotfix Owner" />
              <telerik:GridBoundColumn DataField="Target Release" HeaderText="Target Release" />
              <telerik:GridBoundColumn DataField="Target Date" HeaderText="Target Date" DataFormatString="{0:yyyy-MM-dd}" />
            <ClientEvents OnCommand="function() {}" OnGridCreated="OnGridCreated" OnDataBound="OnDataBound" />



    function OnGridCreated(sender, args) {
      $find('<%= loadPanel.ClientID%>').show('selected');
    function OnDataBound(sender, args) {
      $find('<%= loadPanel.ClientID%>').hide('selected');
    $(function () {
        type: "POST",
        url: "/pageinformation/styleguide.api/internaldocgeneratorws.asmx/getworkitemcollection",
        data: '{ workItems: ' + JSON.stringify(deployment.WorkItems) + ' }',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        cache: true
      }).done(function (data) {
        var tableView = $find('<%= rgSelected.ClientID %>').get_masterTableView();
      }).fail(function (jqXHR, textStatus) {
        // If there is no communication between the server, show an error
        $find('<%= MessageBox.ClientID %>').addError(jqXHR.responseJSON.Message, false);

    Hello Matt,

    If you will be using client binding, I'd recommend you consider the Kendo UI for jQuery grid, as it is desgined for client-side rendering and binding, so it will provide you with more flexibility:

    If you will be binding the grid to a JSON literal, I recommend you follow this demo: The key points:

    • you need the total count of items and to set it to the grid through the  tableView.set_virtualItemCount method
    • you need to put data in controls inside templates in the RowDataBound event
    • if you will be using filtering, you need to handle that through the data source by using the OnCommand event

    I would also recommend firing the data request in the Sys.Application.Load event to ensure it will try to use the grid in its promise after it has been created.
