My gird is declared like so:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="list.aspx.vb" Inherits="User_list" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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

<head runat="server">

<title></title>

</head>

<body>

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

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

<telerik:RadGrid ID="UserGrid" runat="server" AutoGenerateColumns="False" CellSpacing="0" GridLines="None" runat="server">

<MasterTableView>

<Columns>

<telerik:GridBoundColumn AllowFiltering="False" DataField="EmailAddress"

FilterControlAltText="Filter column column" HeaderText="User"

UniqueName="column">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="FullName"

FilterControlAltText="Filter column1 column" HeaderText="Full Name"

UniqueName="column1">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

</form>

</body>

</html>

...and I bind to a generic list in the codebehind...

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

If Not Page.IsPostBack Then

Dim Users As List(Of User) = UserManager.GetAll(ApplicationVariables.CurrentUser.InstitutionId)

UserGrid.DataSource = Users

UserGrid.DataBind()

End If

End Sub

My list ("Users") is a list of objects with the following definition:
Public Class User

Public UserId As Integer = 0

Public Password As String = String.Empty

Public EmailAddress As String = String.Empty

Public InstitutionId As Integer = 0

Public FullName As String = String.Empty

End Class

There are two users in my source data. The grid displays the right number of rows, but the cells are empty:
Empty Grid

I'm sure this is an obvious mistake. Any help is appreciated.

Hello,

Thank you for contacting us.

Generally, your code looks correct. However, you have not shared what is the body of the GetAll method and how the data is initialized.

Could you share your full page source code along with the code-behind file? Thus I will be able to examine your code and let you know what could possibly lead to this behavior.

I am looking forward your reply.
