Watermark / hint text / placeholder TextBox

Question

How can I put some text into a TextBox which is removed automatically when user types something in it?

Answer 1

you can use GetFocus() and LostFocus() events to do this

here is the example:

    private void txtData1_GetFocus(object sender, RoutedEventArgs e)
    {
        if (txtData1.Text == "TextBox1abc")
        {
            txtData1.Text = string.Empty;
        }
    }

    private void txtData1_LostFocus(object sender, RoutedEventArgs e)
    {
        if (txtData1.Text == string.Empty)
        {
            txtData1.Text = "TextBox1abc";
        }
    }
