Default Retrieving Images from SQL Server

Hello and thanks for taking a moment. I am trying to retrieve and display an image that is stored in SQL Server 2000. My aspx code is as follows:

  <meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
  <meta name="CODE_LANGUAGE" Content="C#">
  <meta name="vs_defaultClientScript" content="JavaScript">
  <meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">
 <body MS_POSITIONING="GridLayout">
  <form id="Form1" method="post" runat="server">
  <asp:DataGrid id="DataGrid3" HorizontalAlign='Left' runat="server" AutoGenerateColumns="true"
      <asp:TemplateColumn HeaderText="Image">
            Width="150" Height="125"
            ImageUrl='<%# FormatURL(DataBinder.Eval(Container.DataItem, "InventoryItemPhoto")) %>'
            Runat=server />

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------My code behind file is below VS 2003 does not like my datareader. It says the following:

 'System.Data.SqlClient.SqlDataReader' does not contain a definition for 'Items'

If there are any suggestions as to what I am doing wrong I would appreciate the input. - Jason

Try: myDataReader("JPEG") though in C# it may actually be this: myDataReader["JPEG"]

--Stole this from a moderator

I will only tell you how to do it, not do it for you.
Unless, of course, you want to hire me to do work for you.
