How can I use a mask for a textbox?

How can I use a mask for the textbox?

I am using Guna2 framework and there is no MaskedTextBox there.

You need to make a mask manually. I tried some options from the internet, but they didn't work.

Before that, I tried handling keyboard presses and separating with dots after every 2 characters. But this is a bad way. Who knows how to do it using DateTime or other methods?

    private void guna2TextBox20_TextChanged(object sender, EventArgs e)
    {
        guna2TextBox20.Text = GetMaskedString("dd.MM/yyyy",guna2TextBox20.Text);
    }
    public static string GetMaskedString(string mask, string input)
    {
        try
        {
            MaskedTextProvider provider = new MaskedTextProvider(mask);
            provider.Add(input);
            return provider.ToDisplayString();
        }
        catch { return input; }
    }

I've tried this. Works, but enters the date backwards

    private void guna2TextBox20_TextChanged(object sender, EventArgs e)
    {
        MaskedTextBox mask = new MaskedTextBox();
        mask.Mask = "00/00/0000";
        mask.Text = guna2TextBox20.Text;
        guna2TextBox20.Text = mask.Text;
    }

Just add a MaskedTextBox control to your form and put its visibility to false.

It would create a mapping system which your MaskedTextProvider would be using

MaskedTextBox control is a part of Windows Forms and should be available in the Toolbox like in this screen shot
