Question Formatting Number entered in Textbox

[LillyPooh]

hey

I have a web form with about 5 textboxes that I expect the user to fill with numbers. I need to view those numbers in decimal format (16,2) as soon as the user navigates away from the textbox, even if the user doesn't enter decimal numbers. I know the function that converts to decimal, but I'm a little confused about when and where to call it. I don't want to use the textchanged method with autopostback set to true, cause I already have a couple of drop down lists that use that, and it won't be very user friendly if the page keeps on reloading every time he/she chooses or enters something.

I read somewhere that i could change the textbox data type (which is string by default) to whatever to achieve that, but I couldn't find out how to do that though. Someone told me to try using update panels, but I've never worked with them before and I couldn't find good resources explaining how to use them.

So what you guys suggest I do?

Thanks in advance!

Having it on the textboxes and having OnTextChanged code execute wont be a problem if you put all your autopostback controls in an UpdatePanel. That way, only that part of the page will PostBack and your user will be none the wiser.
