I need to use DataList inside another DataList

Question

<asp:DataList ID="DataListDziennik" runat="server"
DataSourceID="SqlDataSourcePrzedmioty">
<ItemTemplate>
    <asp:Label ID="LabelPrzedmiot" runat="server" Text='<%# Eval("przedmiot") %>' />

    ...

        <asp:DataList ID="DataListOceny" runat="server" 
            DataSourceID="SqlDataSourceOceny" 
            RepeatDirection="Horizontal" 
            OnItemCommand="DataListOceny_ItemCommandOceny"
            OnEditCommand="DataListOceny_EditCommandOceny">

            <EditItemTemplate>

                <asp:TextBox ID="TextBoxOcena" runat="server" Text='<%# Bind("lista") %>' />
                <td><asp:Button ID="ButtonZapisz" CommandName="Update" runat="server" Text="Zapisz" /></td>

            </EditItemTemplate>

            <ItemTemplate>

                <asp:TextBox Width="20" ID="TextBoxOcena" ReadOnly="true" Text='<%# Eval("lista") %>' runat="server"></asp:TextBox>
                <td><asp:Button ID="ButtonEdytuj" CommandName="Edit" runat="server" Text="Edytuj" /></td>

            </ItemTemplate>
        </asp:DataList>
    </td>
</ItemTemplate>

When I write this in code behind:

       protected void DataListOceny_EditCommand(object source, DataListCommandEventArgs e)
{
    DataListOceny.EditItemIndex = e.Item.ItemIndex;

    DataListOceny.DataBind();
}

Visual Studio tells me that DataListOceny does not exist in current content. I just want to be able edit items on DataListOceny after clicking the "edit" button, please give me full code in code behind part... for edit DataListOceny .

What you asking is same like the below thread.. You need to find the DataListOceny Control on each row of DataListDziennik to bind it

Using FindControl() to find control

And Here is some good example on the same
