Do you want this same behavior for TextBoxes which are inside other ContainerControls, like Panels ?

Handle the TextBox.Enter and Leave events:

private void myTextBox_Enter(object sender, EventArgs e)
    {
    TextBox tb = sender as TextBox;
    if (tb != null)
        {
        tb.BackColor = Color.Silver;
        }
    }

private void myTextBox_Leave(object sender, EventArgs e)
    {
    TextBox tb = sender as TextBox;
    if (tb != null)
        {
        tb.BackColor = Color.White;
        }
    }
