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.
