    Hi All,

    I am using Radgrid into User Control. that user control defined into RadWindow in aspx page. when i am clicking the link button that window will popup and i want to assign datasource like. radgrid.get_masterTableView().set_dataSource(new Array()). but radgrid.get_masterTableView() return null values. i want to assign datasource only in client side. please let me know how to solve this issue.

    Here i have attached code.

    in aspx page

    <asp:LinkButton ID="lnkSymptoms" runat="server" Text="Symptoms : " OnClientClick="return lnkSymptom_clientClick()"></asp:LinkButton>
    <telerik:RadWindow runat="server" ID="rwSymptoms" Title="Symptoms" VisibleStatusbar="false"
                        Width="600px" Height="430px" Modal="true" EnableShadow="true" Skin="Web20" Opacity="100">
                            <div id="divSymptoms" runat="server">
                                <ucSymptom:ucSymptom ID="ucSymptomsCtrl" runat="server" />


     function lnkSymptom_clientClick(sender, args) {
    var rgSymptoms = $find("ctl00_ContentPlaceHolder1_rwSymptoms_C_ucSymptomsCtrl_rgSymptoms").get_masterTableView();             
                        rgSymptoms.set_dataSource(new Array());

    ascx page

    <telerik:RadGrid ID="rgSymptoms" runat="server" HeaderStyle-Font-Bold="true" HeaderStyle-HorizontalAlign="Center"
                    Width="370px" EnableViewState="false" PagerStyle-Visible="false" >
                    <ClientSettings ClientEvents-OnCommand="function() {}" >                  
                    <MasterTableView CommandItemDisplay="None" AutoGenerateColumns="false" AllowSorting="true"
                        AllowPaging="true" DataKeyNames="sys_con_id" ClientDataKeyNames="sys_con_id">
                                No records to be displayed</center>
                            <telerik:GridTemplateColumn UniqueName="Description" HeaderText="Condition">
                                <ItemStyle VerticalAlign="Top" Wrap="false" HorizontalAlign="Left" />
                                <HeaderStyle Width="220px" />
                                    <asp:Label ID="Description" runat="server" SkinID="NoBold"></asp:Label>
                                    <asp:TextBox runat="server" ID="txtDesc" Style="display: none;" onchange="javascript:return UpdateOtherValue(this)"></asp:TextBox>

    Hello Dhamodharan,

    Please try out the following:
    function lnkSymptom_clientClick(sender, args)
                var window = $find('<%= rwSymptoms.ClientID %>');
                var grid = $telerik.findControl(window.get_contentElement(), "rgSymptoms");
                grid .get_masterTableView();
                return false;

    All the best,
