Did you add the control to the Form.Controls collection after you created it?

You can get your text box value by the following code:

Control cc = this.Controls.Find(txtFName, true).First();
string value = cc.Text;

What John means is this,

C#

Might be helpful,

C#

private void btnCreate_Click(object sender, EventArgs e)
{
     TextBox txtBox = new TextBox();
     txtBox.Name = "txtFName";
     txtBox.Text = "Hello world";
     Controls.Add(txtBox);
}
private void btnFind_Click(object sender, EventArgs e)
{
     TextBox rc = (TextBox)FindDynamicControlByName("txtFName");
}
private Control FindDynamicControlByName(string controlName)
{
      return Controls.Find(controlName, true).FirstOrDefault();
}

For Ref:
Control.Controlcollection.Find[^]
