Virtualization Throwing Error for VS 2010 with Version 2015.1.318.40

[Jaish]

I am binding my grid using AJAX and PageMethods like below

$(document).ready(function () {

PageMethods.GetEmployees(updateGrid, err);
//bindSourceGrid();
});

function updateGrid(result) {

var tableView = $find("<%= SourceGrid.ClientID %>").get_masterTableView();

tableView.set_dataSource(result);

tableView.dataBind();
}

function err(e) {

}

function RadGrid1_DataBound(sender, args) {
alert("Grid with id: " + sender.get_element().id + " bound on the client");
}

function SourceGrid_RowDataBound(sender, args) {
}

function GridCreated(sender, eventArgs) {


}



I am getting result back from server, but during rendering getting javascript error (Please see the attached image). My aspx is like below which hasn't any master and an independent sample page with reference to JQuery. Any clue here would be appreciated.

<telerik:RadScriptManager ID="ScriptManager" runat="server" />

Hi Jaish,

Virtualization is a great feature you can use. However, it has certain limitations.

Please make sure that you are not using grouping, row or cell selection, templates. If you would like additional information on Virtualization you would find the following article interesting.
