Why is my ASP:Image not accessible from the vb?

I just figured this out. Figured it might bite someone else someday.

Given this code in an aspx file:

      <table width="100%">
            <tr>
                  <td class="normaltxt10" colSpan="50">
                  <!--
                  <asp:DataGrid id="dgImage" runat="server" ShowHeader="False"
                                AutoGenerateColumns="False" TabIndex="5">
                        <Columns>
                              <asp:BoundColumn Visible="False" DataField="file"></asp:BoundColumn>
                              <asp:TemplateColumn>
                                    <ItemTemplate>
                                    -->
                              <asp:Image ID="screenShotImage" Runat="server"></asp:Image>
                                    <!--
                                    </ItemTemplate>
                              </asp:TemplateColumn>
                        </Columns>
                  </asp:DataGrid>
                  -->
                  </td>
            </tr>
      </table>

Why would screenShotImage be not accessible in the vb code behind?

Answer: because it's in the commented out DataGrid, and in my case, dgImage wasn't referenced at all in the vb.
Removing the commented out DataGrid will fix this.
Like so:

      <table width="100%">
            <tr>
                  <td class="normaltxt10" colSpan="50">
                        <asp:Image ID="screenShotImage" Runat="server"></asp:Image> 
                  </td>
            </tr>
      </table>

This is stupid in my opinion, but whatever. Now we know.
