    I am trying to bind a radgrid after a button click event using Javacript the code below ... 

    aspx page: on page load this is empty


    <telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" >












    telerik:GridTemplateColumn >






    <HeaderStyle CssClass="header" Width="5%" Height="7%" />












    <asp:CheckBox ID="cbSelectAll" runat="server" onClick="checkedAll(this);"></asp:CheckBox>



















    <asp:CheckBox ID="chkBox" AutoPostBack="false" runat="server" ></asp:CheckBox>


















    telerik:GridBoundColumn UniqueName="SalesNo" DataField="SalesNo" HeaderText=" Sales Number" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" >



    <HeaderStyle CssClass="header" />














    //results is data returned from a web service call using ajax




    PopulateSalesGrid(results) {






    var rgGrid  = $find("<%= RadGrid1.ClientID %>").get_masterTableView();


    rgGrid.set_dataSource(results); // here i get error value cannot be null





    ** I would perfer not to have the grid populated on page load.

    I also tried binding the radgrid on page load (code behind) and hiding it before button clicking event .... and showing if after the click event. But the issue here is ... when you cllick on the 'checked All' checkbox it gets all the values from the previous (page load) databind and not the values from the PopulateSalesGrid function.

    Any ideas how to fix this?

    Hello Diane,

    Make sure that you have specified the web service method appropriately. Check the following help documentation which explains more about this.

    This question seems unreadable to me.
