    Check this article Chris..

    private voidtextBox1_KeyPress(object sender, KeyPressEventArgs e)

            {           

    if (char.IsDigit(e.KeyChar)== false && e.KeyChar != '.' && e.KeyChar!='\b')

    //checking whether pressed key is number, decimal orbackspace.

    //If false then we will set Handled variable ofKeyPressEventArgs to true.

    //By doing this system will get a message that character of keypressed

    //is executed and hence aplpa numeric character will not bedisplayed

    //except decimal.

                    e.Handled=true;

                elseif (e.KeyChar == '.')

                    if(textBox1.Text.Contains('.'))

                        e.Handled=true;           

    //checking whether decimal key is pressed or not, if truethen checking

    //whether decimal is already present or not, as we can haveonly

    //one decimal point in a text box.

            }
