Question

Is it possible to create a textbox in Visual Studio like this:

Answer 1

You would just need to handle three TextBox events, in the Designer set the text of the TextBox to “username” and make it Font Italics then set TextBox BackColor to LightYellow,the rest is handled by Event handlers…

     private void textBox1_TextChanged(object sender, EventArgs e)
    {
        if (textBox1.Text == "")
            ChangeTextBoxtoWatermark();
    }

    private void textBox1_MouseEnter(object sender, EventArgs e)
    {
        if (textBox1.Text == "username")
        {
            textBox1.Text = "";
            textBox1.Font = new Font(this.Font, FontStyle.Regular);
            textBox1.BackColor = Color.White;
        }
    }

    private void textBox1_MouseLeave(object sender, EventArgs e)
    {
        if (textBox1.Text == "")
            ChangeTextBoxtoWatermark();
    }

    private void ChangeTextBoxtoWatermark()
    {
        textBox1.Font = new Font(this.Font, FontStyle.Italic);
        textBox1.BackColor = Color.LightYellow;
        textBox1.Text = "username";
    }

I have checked it and it works fine 🙂
