REST Service Calls with grid client binding

[Chris Messineo]

I checked out the tutorial at this url:  http://blogs.telerik.com/VladimirEnchev/Posts/08-11-12/REST_Service_Calls_with_grid_client_binding.aspx?ReturnURL=%2fVladimirEnchev%2fPosts.aspx

Nice article, one question though, if I get zero hits and use the set_virtualItemCount(0) the grid does not show that there are zero hits, do I maybey need to call an update or refresh method on the grid?

Thanks

Hello Chris,

Generally if you return empty collection the grid should handle this automatically. I notice unfortunately that NoRecordsTemplate/NoMasterRecordsText does not work properly in this case and we have fixed this immediately. The fix will be available next week with our service pack.

Thanks for looking into this. 

Kind of a hack but I just manipulated the Table in javascript to show no results:

Something like:

                    var myTable = document.getElementById("ctl00_ContentPlaceHolder1_RadGrid1_ctl00");
                    myTable.deleteRow(1);                   
                    myTable.deleteTFoot();                                                           

                    var newrow = myTable.insertRow(1) //add new row to end of table
                   
                    newrow.height = "30";
                    var newcell_0 = newrow.insertCell(0) //insert new cell to row
                    newcell_0.align = "right";
                    newcell_0.innerHTML = "<b>No&nbsp;</b>";

                    var newcell_1 = newrow.insertCell(1);
                    newcell_1.innerHTML = "<b>records found.</b>";

Hello Chris,

You can use the following code to hide grid data items if there are no records to display.

/listen for OnDataBound client event/

<ClientEvents OnDataBound="Grid_DataBound" />

/code for the handler/

    <script type="text/javascript">
        function Grid_DataBound(sender, args)
        {
            if ($telerik.$(".rgNoRecords", sender.get_masterTableView().get_element())
                    .css("display") != "none")
            {
                $telerik.$(".GridRow_Office2007", sender.get_masterTableView().get_element())
                    .css("display", "none");
                $telerik.$(".GridAltRow_Office2007", sender.get_masterTableView().get_element())
                    .css("display", "none");
            }
        }
    </script>
