Question

Adding meta attribute to asp.table tag

Asked by: PHD

Hello,

I develop an asp.net  2.0 application with visual studio 2005.
I have a webpage with an asp:table named "t_summary". The table contains rows and cells. Cells contain webcontrols like textboxes or labels.

In the code behind of the page, I could reference a textbox like this t_summary.Rows[0].Cells[1].FindControl("l_current_week2").
But since I added the meta tags to globalize the page (meta:resourcekey="MyTableResource1")
the findcontrol method returns null .  When I add  t_summary.Rows[0].Cells[1].Controls.Count to the watch,  it gives me 0.

Someone has an logical explanation ?



Design code :
<asp:Table ID="t_summary" runat="server" EnableTheming="False" CellPadding="0" CellSpacing="0" meta:resourcekey="t_summaryResource1">
                <asp:TableHeaderRow runat="server" meta:resourcekey="TableHeaderRowResource1">
                    <asp:TableHeaderCell runat="server" meta:resourcekey="TableHeaderCellResource1">

                    </asp:TableHeaderCell>

second shot. I hope this new explanation will be more interesting for experts :-)

I have a simpla aspx page with 1 table. Tha table has 2 rows and each rows has 2 cells. The first cell of the first row containes 1 Textbox.

Without the meta attribute in the parent cell of the text box,  TextBox tb = ((TextBox)Table1.Rows[0].Cells[0].FindControl("tb_nom")); is ok.
But
with the meta attribute in the parent cell of the textbox control, tb is always null.

Why ?
