I am having an odd problem when I try to add a GridTemplateColumn with an embedded ASP.Net control to my RadGrid. For some reason, the table is not rendering correctly; the ASP.Net is being renedered at the beginning of the grid instead of the opening table tag for the table.

I am using Q3 2013 ASP.Net for AJAX and VS Express 2013 for Web.

Here is the code (aspx file, then vb file):

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="gridDDLTest.aspx.vb" Inherits="NikkorLinksAdmin.gridDDLTest" %>

<%@ 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>

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

<div>

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

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

<MasterTableView EnableColumnsViewState="False">

<Columns>

<telerik:GridBoundColumn DataField="ItemId" FilterControlAltText="Filter column column" UniqueName="column">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="ItemName" FilterControlAltText="Filter column1 column" UniqueName="column1">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="ItemOrder" FilterControlAltText="Filter column2 column" UniqueName="column2">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn>

<ItemTemplate>

<asp:Label runat="server" ID="lblOrder" Text="12"></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

</div>

</form>

</body>

</html

>



vb file:




Public Class gridDDLTest
    Inherits System.Web.UI.Page
 
    Public Class BoundClass
        Private _itemId As Integer
        Property ItemId As Integer
            Get
                Return _itemId
            End Get
            Set(value As Integer)
                _itemId = value
            End Set
        End Property
 
        Private _itemName As String
        Property ItemName As String
            Get
                Return _itemName
            End Get
            Set(value As String)
                _itemName = value
            End Set
        End Property
 
        Private _itemOrder As Integer
        Property ItemOrder As Integer
            Get
                Return _itemOrder
            End Get
            Set(value As Integer)
                _itemOrder = value
            End Set
        End Property
 
        Public Sub New(id As Integer, name As String, order As Integer)
            Me.ItemId = id
            Me.ItemName = name
            Me.ItemOrder = order
        End Sub
    End Class
 
    Private _itemsForBinding As New Generic.List(Of BoundClass)
    Public ReadOnly Property ItemsForBinding As Generic.List(Of BoundClass)
        Get
            If _itemsForBinding.Count = 0 Then
                _itemsForBinding.Add(New BoundClass(1, "Name1", 4))
                _itemsForBinding.Add(New BoundClass(1, "Name2", 2))
                _itemsForBinding.Add(New BoundClass(1, "Name3", 1))
                _itemsForBinding.Add(New BoundClass(1, "Name4", 3))
            End If
            Return _itemsForBinding
        End Get
    End Property
 
 
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            Me.grdTest.DataSource = ItemsForBinding
            Me.grdTest.DataBind()
        End If
    End Sub
 
End Class



Finally, here is a sample of what the output looks like; note the lack of an opening tag.




        <div id="grdTest" class="RadGrid RadGrid_Default">
 
<span id="grdTest_ctl00_ctl04_lblOrder">12</span>
                        </td>
    </tr><tr class="rgAltRow" id="grdTest_ctl00__1">
        <td>1</td><td>Name2</td><td>2</td><td>
                            <span id="grdTest_ctl00_ctl06_lblOrder">12</span>
                        </td>
    </tr><tr class="rgRow" id="grdTest_ctl00__2">
        <td>1</td><td>Name3</td><td>1</td><td>
                            <span id="grdTest_ctl00_ctl08_lblOrder">12</span>
                        </td>
    </tr><tr class="rgAltRow" id="grdTest_ctl00__3">
        <td>1</td><td>Name4</td><td>3</td><td>
                            <span id="grdTest_ctl00_ctl10_lblOrder">12</span>
                        </td>
    </tr>
    </tbody>
 
</table><input id="grdTest_ClientState" name="grdTest_ClientState" type="hidden" />
    </div>
