Hi,

in my aspx page I have somting like that:

<asp:Content ID="Content1" ContentPlaceHolderID="Body" Runat="Server">
    <asp:UpdatePanel ID="UpdatePanel1" ChildrenAsTriggers="true" UpdateMode="Conditional" runat="server" >
        <ContentTemplate>
            <asp:Panel ID="Panel1" runat="server">

<asp:Table ID="PO_Tags" Width="90%" BorderWidth="1" HorizontalAlign="Center" 
                CellPadding ="2" CellSpacing ="1" visible="false" runat="server">
                <asp:TableHeaderRow>
                    <asp:TableHeaderCell BackColor="AliceBlue" >Tag Name<br /><br /></asp:TableHeaderCell>
                    <asp:TableHeaderCell BackColor="AliceBlue" >Association Type<br /><br /></asp:TableHeaderCell>
                    <asp:TableHeaderCell BackColor="AliceBlue" >Tag Description<br /><br /></asp:TableHeaderCell>
                    <asp:TableHeaderCell BackColor="AliceBlue" >Tag Value<br /><br /></asp:TableHeaderCell>
                </asp:TableHeaderRow>
            </asp:Table>
           
            <br />
            <asp:Button ID="Submit" Text="Submit" OnClick="Submit_Click" Visible="false" runat="server" />
           
            </asp:Panel>
        </ContentTemplate>
     </asp:UpdatePanel> 
</asp:Content>
 

from c# code I'm building my table rows dynamicly:

while (rdr.Read())
                    {
                        trRow = new TableRow();
                       
                        tcCell = new TableCell();
                        tcCell.Text = rdr["Label"].ToString();
                        trRow.Cells.Add(tcCell);

                        tcCell = new TableCell();
                        switch (rdr["ControlType"].ToString())
                        {
                            case "Text":
                            case "Integer":
                            case "Real":
                                TextBox ctrl1 = new TextBox();
                                ctrl1.ID = String.format("tagCtrl{0}" ,countTagsControls);
                                ctrl1.Text = "Test";
                                tcCell.Controls.Add(ctrl1);
                                //this.UpdatePanel1.ContentTemplateContainer.Controls.Add(ctrl1);
                                break;

                              .......

                     }

           trRow.Cells.Add(tcCell);
           PO_Tags.Rows.Add(trRow);

Then I'm trying to get the values of those controls:

TextBox txtCtl = (TextBox)UpdatePanel1.FindControl(String.format("tagCtrl{0}", i));
                    switch (rdr["ControlType"].ToString())
                    {
                        case "Text":
                            string v1 = txtCtl.Text.ToString();
                            break;

But it's not working!!
What I'm missing?!

Thanks in advance.
