I have some labels and textboxes that I need to create within a parentcontrol called"divFieldsSpace". This happens on the SelectedIndex change of a dropdown. This works fine. (See Code)
        protected void ddlCV_category_OnSelectedIndexChanged(object sender, EventArgs e)
        {
           
            ClaimInfo ci = new ClaimInfo();
            DataSet ds;
            ds = ci.GetvendorCategoryFormFields(Convert.ToInt32(ddlCV_category.SelectedValue));

            foreach (DataRow dr in ds.Tables[0].Rows)
            {
                foreach (DataColumn column in dr.Table.Columns)
                {
                    if (dr[column].ToString().Trim() != "")
                    {
                        Label myLabel = new Label();
                        myLabel.Text = "<b>" + dr[column].ToString() + "</b>";
                        divFieldsSpace.Controls.Add(myLabel);

                        TextBox myTextBox = new TextBox();
                        myTextBox.ID = "txt" + column.ColumnName;


                        divFieldsSpace.Controls.Add(myTextBox);

                        Label myBreakLabel = new Label();
                        myBreakLabel.Text = "<br><br>";
                        divFieldsSpace.Controls.Add(myBreakLabel);

                    }

                }


            }
        }
However, I then need to get the value entered in the textboxes after a button click. No matter what I do FindControl() never seems to work in trying to get the textboxes. As mentioned before , I'm almost certain I know the parent control (divFieldsSpace) so I'm somewhat at a loss at this point. The textboxes show up right where they are suppose to. Is there something else I need to do upon creation of the textboxes. I do have multiple pageviews on the page this runs on , but again, I would think as long as I knew the parent control I would be in good shape. Any advice or direction would be greatly appreciated.

//code always hits the catch, txtVarchar1 within divFieldSpace is never found...
         string varchar1 
           
             try
            {
             
                varchar1 = ((TextBox)divFieldsSpace.FindControl("txtVarchar1")).Text;
            }
            catch
            {
                varchar1 = "";
            }

//I even tried a recursive search to see if I could see child controls... there's nothing
    foreach (Control childControl in divFieldsSpace.Controls)
            {
                string name = childControl.ID;
            }
