We just recently upgraded from Q3 2011 to the Q1 2013 version of the report tool. We are putting a QR code in the footer of each page to identify it when scanned. Since we don't know the page number at the time we generate the QR code we are just increment a counter every time the OnDataBinding Event of the picture box that displays the QR code is called. Before the upgrade this worked. After the upgrade the event is getting fired 4 times for every page and it's messing with our page counts. Any suggestions on how to accomplish what we need to do?

Hello,

In general you should use the PageNumber global object in an expression to obtain the current page number. If you want to do something more specific based on the page number value you can pass it as an argument to a user defined function. Please, note as well that the PageNumber and PageCount global objects are only available for the items in the page sections (PageHeader/PageFooter).

Kind regards,

Have you tried the new visualization options in Telerik Reporting Q1 2013? You can get them from your account.

We ended up using a user defined function. This lets us get the page number to the code we are using to generate the QR code. The issue we have now is with the PageCount global object. We are keeping a record of how many pages are in a document (so we can know if they have all been scanned back in) and in a few of our reports the PageCount will read higher than the number of pages the report ends up being. For example I have a user function on a text box in the PageFooter. If I throw a break point on my user function I see that it gets called 8 times. One one of those calls both the PageNumber and the PageCount are 3 so we are creating a record saying this report has 2 pages. On subsequent calls the PageCount is 2. Is there a way to get the final PageCount?

Hello,

Despite how many times the user function has been called the PageCount value should be always the same. Please, check whether you pass correctly the PageCount object to the user function.
