Sorry, I accidentally pressed "Post"

We are using RadGrid from Telerik ASP.NET Ajax library.

This is my demo .aspx code:

<!DOCTYPE html>

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

<head runat="server">

<title>Telerik ASP.NET Example</title>

</head>

<body>

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

<telerik:RadScriptManager runat="server" ID="RadScriptManager1"/>

<telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" runat="server">

<ClientSettings>

<Scrolling AllowScroll="True" UseStaticHeaders="True" FrozenColumnsCount="2"></Scrolling>

</ClientSettings>

<MasterTableView ></MasterTableView>

<HeaderStyle Width="200px" />

</telerik:RadGrid>

</form>

</body>

</html>

This is my demo .vb code:

Imports Telerik.Web.UI

Public Class Demo

Inherits System.Web.UI.Page

Public Class PersonData

Private _ID As Int16

Private _Name As String

Private _Age As Int16

Public Property ID() As Int16

Get

Return _ID

End Get

Set(ByVal Value As Int16)

_ID = Value

End Set

End Property

Public Property Name() As String

Get

Return _Name

End Get

Set(ByVal Value As String)

_Name = Value

End Set

End Property

Public Property Age() As Int16

Get

Return _Age

End Get

Set(ByVal Value As Int16)

_Age = Value

End Set

End Property

End Class

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

End Sub

Private Sub RadGrid1_NeedDataSource(sender As Object, e As GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource

RadGrid1.DataSource = New List(Of PersonData)

End Sub

End Class
