Hi Experts,

I was wondering if someone could explain to me the Container class on http://www.w3schools.com/ASPNET/aspnet_repeater.asp

They don't seem to import / reference any other classes, and when I try doing the same thing I am getting an error:
Container' is not declared. It may be inaccessible due to its protection level.

Thanks so much
<form id="Form1" runat="server">
<asp:Repeater runat="server" ID="rpCategory">
    <ItemTemplate>
    <tr>
        <td>
            <asp:RadioButton GroupName="rbLstCategory" runat="server" Text="<% Databinder.Eval(Container.DataItem, "Title", "{0:d}") %>" ></asp:RadioButton>
            </td>
    </tr>
    <tr>
        <td>
            <% DataBinder.Eval(Container.DataItem, "Description", "{0:d}")%>
        </td>
    </tr>
    </ItemTemplate>
</asp:Repeater>
</form>

-- Code Behind --
Private Sub BindRepeater()

	Dim ctl As New myQuestionCategoryController

	Dim arr As ArrayList = ctl.myQuestionCategoryGetByModules(Me.MainModuleID, False, False)

	Me.rpCategory.DataSource = arr
	Me.rpCategory.DataBind()

End Sub

When you bind using Eval you need to use <%# and not only <%

You are using :

<% DataBinder.Eval(Container.DataItem, "Description", "{0:d}")%>

Where it should be  :

<%# DataBinder.Eval(Container.DataItem, "Description", "{0:d}")%>

I modified your code with the right syntax.

Hope it helps.
<form id="Form1" runat="server">
<asp:Repeater runat="server" ID="rpCategory">
    <ItemTemplate>
    <tr>
        <td>
            <asp:RadioButton GroupName="rbLstCategory" runat="server" Text='<%# Databinder.Eval(Container.DataItem, "Title", "{0:d}") %>' ></asp:RadioButton>
            </td>
    </tr>
    <tr>
        <td>
            <%# DataBinder.Eval(Container.DataItem, "Description", "{0:d}")%>
        </td>
    </tr>
    </ItemTemplate>
</asp:Repeater>
</form>
