     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.
            }
