Accepted answer
try like this and create textchanged event and modifie the code if any syntax mistake

protected void txtunits_TextChanged(object sender, EventArgs e)
    {
             int i=100;
if(txtunits.Text!=null && txtunits.Text!=string.Empty)
            txttotalamt.text=(Conver.ToInt32(txtunits.Text)*I).ToString();
    }

Actually The values from txtunit is user input n the value of txttotalamt is constant.

if the user enters the 10 in txtunit, the amount shld get caculated and displayed on txttotalamt after multiplying.

the link u shared has 3 textbox.
i m working with 2.

if the entered units on txtunits is 10 n the constant amt is 100 the multiplication should get displayed on txttotalamt

i was trying int i=100;
txttotalamt.text=txtunits.text* convert.tosrting(i);
but it is displaying an error that * cannot b used
