PayPal with image button ASP.NET ( sandbox account) incorrectly formatted item amount

Easy one for the experts I hope. I am a student, please help!

I have an incorrectly formatted amount when I checkout in Paypal with my asp.net page, any tips?

Here is my code in c# asp:

  <asp:ImageButton ID="ImageButton3" runat="server" 
       ImageUrl="~/Catalog/Images/Thumbs/buynow.jpg" 
       PostBackUrl='<%# "https://www.sandbox.paypal.com/cgi-bin/webscr?" +
              "cmd=_xclick" + 
              "&[email protected]" +
              // seller email is also static
              "&item_name=" + Eval("ModelName") +
              // ValueX is dynamic name of product item
              "&amount=" + Eval("UnitCost") +
              // ValueY is dynamic cost of product item
              "&currency_code=AUD" // this is also static
        %>'
  />

What you try to do is simple NOT working.

The data item_name, amount etc, must be send using POST and not place them on the url using GET.

Also, by placing the PostBackUrl on this button you post all the page data to the paypal, and not the actually data that paypal needs.

The correct way is to make a totally custom made form like paypal ask on his examples and the manual, and this can not be done that way from a usually asp.net form.

One trick that you can make is to use a dynamic form maker, as on this example:

http://www.codeproject.com/Articles/37539/Redirect-and-POST-in-ASP-NET

and ether make dynamic post, ether place your buttons there and ask the user to click on it.

Also you can consider this articles with sample code:

And do not forget the paypal SDK for asp.net:
