  If the item is in a table that is dynamically generated, you need to use the <TableName>.FindControl(id)

  You need to go down to the lowest level to find the control. If the table name is dynamic, you'll need to do multiple find controls to get down to the textbox.

  Dim t = (Table)Page.FindControl(<tableName>)
  Dim tBox = t.FindControl(id)

  If I've helped you, please mark my post as an Answer. Thanks.

  You won't find the dynamically created control itself by the FindControl method as it is not preserved between postbacks. But you can find the VALUE of the dynamicallt created TextBox, that is the text in it, in the Request.Form collection.

  If you loop through the Request.Form collection, you will find the value, i.e. the text, in the textbox:

   for (int i = 0; i < Request.Form.Keys.Count; ++i)
              {
                  Response.Write(Request.Form[i]);
              }
