See you there!
I previously blogged a sample demonstrating how to use the AJAX Control Toolkit's dynamic population functionality with a data-bound ModalPopup. That sample was well received, but some of the changes that happened as part of the ASP.NET AJAX Beta 1 and Beta 2 releases have rendered the sample code I originally posted un-runnable on current builds.
No worries - it's a simple matter to update the sample and the exercise should serve as a good example of some of the things that need to be done as part of an upgrade. (For a far more in depth guide to upgrading, please refer to Shawn's AJAX Control Toolkit Migration Guide and follow-up about upgrading Web Services/Methods.)
Referring to the sample code I posted earlier as a starting point, the 5 things we need to do to update it are:
That's it! As you can see, it's mostly simple "find-and-replace" naming changes that can easily be applied to an entire site at once. The XxxProperties change is slightly more involved, but requires very little effort since it's basically just a "cut-and-paste" operation. The web method changes are also a little bit of effort, but the changes themselves are simple and it's easy to find where to make them by searching for the pre-existing "WebMethod" attribute. Nothing here is risky or error-prone and - with the exception of the web method changes - the compiler will report all of them as errors until they're fixed correctly.
For completeness, here's a reminder of what dynamic population looks like in action:
And here's the complete sample code after the changes discussed above have been applied. This sample runs fine on the ASP.NET AJAX Beta 2 and the AJAX Control Toolkit 61106 release:
