--instead use { double i = double.parse(txtqty.Text); double j = double.parse(txtproductprice.Text); double l = i*j; txttotalprice.Text = l.Tostring(); }

Why you don't use javscript for that calculation?

Here it is.
function Calculate() { document.getElementById('<%=txttotalprice.ClientID%>').value= document.getElementById('<%=txtqty.ClientID%>').value * document.getElementById('<%=txtproductprice.ClientID%>').value }

hii... i hav 3 textbox named:txtqty,txtproductprice,txttotalprice. i want that when the cursor goes to txttotalprice.the txttotalprice textbox get initialized by the value which is multiple of txtqty and txtproductprice.i hav used the textbox changed event of txttotalprice like this: then i hav coded it like this: protected void txttotalprice_TextChanged(object sender, EventArgs e) { string s = txtqty.Text; string k = txtproductprice.Text; int i = Convert.ToInt32(s); int j = Convert.ToInt32(k); int l = i * j; txttotalprice.Text = Convert.ToString(i); } but it doesnt show any value in txttotalprice...
hi you know , i think you`d better not do that like this !!! :-D because ontextchanged , sends the information to the server andyour page relodes and takes so much time ! it`s better to do this on client side with java script something like this :
var quantity = document.getElementById('txtqty').value;
var price = document.getElementById('txtproductprice').value;
document.getElementById('txttotalprice').value = quantity*price;:cool:

Dear Guys, You People have left one thing,onblur event(given by padmanabhan) should be written to Two text boxes(txtqty and txtproductprice).In Function we have to Check whether these two TextBoxes are not null and if it is not so , Then multiply and display data in third textbox. Writing an event for third textbox is of no use here. Sundeep Ganiga

oh i forgot to say something else ;) in your code that you made textboxes you must add this function like this :
-
//as sajjy says function total() { var quantity = document.getElementById('txtqty').value; var price = document.getElementById('txtproductprice').value; document.getElementById('txttotalprice').value = quantity*price; } //call that event in the textbox onblur():

its not workin... function Calculate() { document.getElementById('<%=txttotalprice.ClientID%>').value= document.getElementById('<%=txtqty.ClientID%>').value * document.getElementById('<%=txtproductprice.ClientID%>').value } wat to do...
change it to this one :
function Calculate()
{
document.getElementById('<%=txttotalprice.ClientID%>').value=
document.getElementById('<%=txtqty.ClientID%>').value *
document.getElementById('<%=txtproductprice.ClientID%>').value}
notice that javascript is Case Sencetive ! :-\
