C# - Controls.remove() Method Not Working

I have a web app where the user can create dynamic textboxes at run time. When the user clicks SUBMIT, the form sends data to the database and I want remove the dynamic controls.

The controls are created in the following code:

Table tb = new Table();
tb.ID = "tbl";
for (i = 0; i < myCount; i += 1)
{
TableRow tr = new TableRow();
TextBox txtEmplName = new TextBox();
TextBox txtEmplEmail = new TextBox();
TextBox txtEmplPhone = new TextBox();
TextBox txtEmplPosition = new TextBox();
TextBox txtEmplOfficeID = new TextBox();
txtEmplName.ID = "txtEmplName" + i.ToString();
txtEmplEmail.ID = "txtEmplEmail" + i.ToString();
txtEmplPhone.ID = "txtEmplPhone" + i.ToString();
txtEmplPosition.ID = "txtEmplPosition" + i.ToString();
txtEmplOfficeID.ID = "txtEmplOfficeID" + i.ToString();
tr.Cells.Add(tc);
tb.Rows.Add(tr);
}
Panel1.Controls.Add(tb);
The Remove section of the code is:
Table t = (Table)Page.FindControl("Panel1").FindControl("tbl");
foreach (TableRow tr in t.Rows)
{
for (i = 1; i < myCount; i += 1)
{
string txtEmplName = "txtEmplName" + i;
tr.Controls.Remove(t.FindControl(txtEmplName));
string txtEmplEmail = "txtEmplEmail" + i;
tr.Controls.Remove(t.FindControl(txtEmplEmail));
string txtEmplPhone = "txtEmplPhone" + i;
tr.Controls.Remove(t.FindControl(txtEmplPhone));
string txtEmplPosition = "txtEmplPosition" + i;
tr.Controls.Remove(t.FindControl(txtEmplPosition));
string txtEmplOfficeID = "txtEmplOfficeID" + i;
tr.Controls.Remove(t.FindControl(txtEmplOfficeID));
}
}

However, the textboxes are still visible.
