Hi,

I was working on a small sample that will populate a RadGrid using client side code and when I tried using 'get_masterTableView' function the script threw the following error:
"Object doesn't support property or method 'get_masterTableView'"

Here's my code:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TestWebMethodCall.aspx.cs" Inherits="RestfulServiceClientApp.TestWebMethodCall" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script src="Scripts/jquery-1.11.1.min.js"></script>

<script type="text/javascript">

//<![CDATA[

$(document).ready(function () {

alert('DOM Ready !');

$('<%=RadAjaxLoadingPanel1.ClientID%>').show('<%=grd_ajaxifiedGrid.ClientID %>');

PageMethods.GetData(successMethod);

function successMethod(result) {

alert(result);

var masterTableView = $('<%=grd_ajaxifiedGrid.ClientID %>').get_masterTableView();

masterTableView.set_datasource(result);

masterTableView.dataBind();

$('<%=RadAjaxLoadingPanel1.ClientID%>').hide('<%=grd_ajaxifiedGrid.ClientID %>');

}

});

//]]>

</script>

</telerik:RadCodeBlock>

<form id="form1" runat="server">

<telerik:RadScriptManager runat="server" ID="scrptmgr_radScriptManager" EnablePageMethods="true"></telerik:RadScriptManager>

<telerik:RadGrid ID="grd_ajaxifiedGrid" runat="server" EnableViewState="false" CellSpacing="-1" GridLines="Both" ClientIDMode="Static"

Width="200" Height="400"></telerik:RadGrid>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default"></telerik:RadAjaxLoadingPanel>

<div>

</div>

</form>

</body>

</html>

and here's my Web Method in the code behind:

[WebMethod]

public static List<string> GetData()

{

List<string> myLst = new List<string>();

myLst.Add("Test1");

myLst.Add("Test2");

myLst.Add("Test3");

myLst.Add("Test4");

myLst.Add("Test5");

return myLst;

}

Please, help.

Many thanks in advance.

Hi Ahmed,

This error occurs when the MasterTableView is accessed before the RadGrid is loaded. Please take a look into the following code snippet I tried to bind the RadGrid on page load.

ASPX:

<telerik:RadGrid ID="grd_ajaxifiedGrid" runat="server" EnableViewState="false" CellSpacing="-1" GridLines="Both" Width="200" Height="400">

<MasterTableView>

<Columns>

<telerik:GridTemplateColumn>

<ItemTemplate>

<asp:Label ID="Label1" runat="server" ></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

C#:

protected override void OnInit(System.EventArgs e)

{

base.OnInit(e);

grd_ajaxifiedGrid.NeedDataSource += new Telerik.Web.UI.GridNeedDataSourceEventHandler(RadGrid1_NeedDataSource);

}

void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

grd_ajaxifiedGrid.DataSource = new List<string>();

}

[WebMethod]

public static List<string> GetData()

{

List<string> myLst = new List<string>();

myLst.Add("Test1");

myLst.Add("Test2");

myLst.Add("Test3");

myLst.Add("Test4");

myLst.Add("Test5");

return myLst;

}

JavaScript:

$(document).ready(function () {

PageMethods.GetData(successMethod);

function successMethod(result) {

var masterTableView = $find('<%=grd_ajaxifiedGrid.ClientID %>').get_masterTableView();

masterTableView.set_dataSource(result);

masterTableView.dataBind();

}

});

Thanks,
Princy.
