You will have to learn javascript or C#. ASP.NET does not matter.

I recommend trying to write the code yourself.   You have a lot of posts on these forums and most of the time you are looking for the community to write your code.

On the C# side it is simple as declaring a decimal type and applying a numeric format.   See the docs.

If you need a JavaScript solution then see the following.

    protected void Button1_Click(object sender, EventArgs e)
    {
        TextBox1.Text = string.Format("{0:N3}", Convert.ToDouble(TextBox1.Text));
    }
