Add static text to TextBox

I'm developing a custom TextBox for displaying and editing currency values. What I would like is to have a currency symbol v开发者_Go百科isible within the TextBox on the left side. Overriding OnPaint of a TextBox is sort of horror after Googling and doing some tests. Anybody have other ideas? Maybe add the symbol as a background picture to the TextBox (if that is rather simple)?

why don't you put a label before the text box and display the currency value?

why not just:

    private void textBox1_TextChanged(object sender, EventArgs e)
    {
        if (!textBox1.Text.StartsWith("£"))
        {
            textBox1.Text = string.Concat("£", textBox1.Text);
            textBox1.Select(textBox1.Text.Length, 0);
        }
    }

You could do several things:

• Add a "$" in your get property of the textbox
• Add a label with a static $
• Create a user control with a $ as a label and reuse it with your custom textbox

Another option would be to use a watermark in your textbox--please see here for an example of how to do this.

You can use a MaskedTextBox instead of a TextBox. http://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox.mask.aspx

For your Mask property, use "$" for the currency symbol.
