从C＃Table控件中的控件访问数据？

Question

As the title suggests, I'm having trouble accessing data in my Table control (System.Web.UI.WebControls.Table). The layout is basically a dynamic web-based spreadsheet with TextBox controls in each TableCell. I was trying to do something like the code below, but I can't access the data. Any help would be appreciated.

        foreach (Control c in this.Controls)
        {
            if (c.GetType().ToString() == "System.Windows.Form.Textbox")
            { 
                TextBox t = c as TextBox;
                if (t.Text.Trim() != "")
                {
                    // Do more things based on t.ID...
                }
             }
         }

You can try to do it like:

        foreach (var control in this.Controls.OfType<TextBox>())
        {
            if (control.Text.Trim() != string.Empty)
            {
                //do your code..
            }
        }
