Delay's Blog is the blog of David Anson, a Microsoft developer who works with C#, XAML, HTML, and Azure.
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:
As I blogged earlier, I presented the AMS302: "Atlas" AJAX Control Toolkit Unleashed: Creating Rich Client-Side Controls and Components session at the Microsoft ASP.NET Connections conference a few hours ago. This was my first ever presentation at a conference and it was a lot of fun! I hope those of you who attended enjoyed the talk and learned more about the Toolkit - it was great to have an opportunity to talk to you in person!
I've attached my slide deck and the demo content to this post so that anyone who's interested can download it and play around on their own machines.
We're always looking for more contributors and additional control ideas, so please let me know if you want to contribute!
I previously blogged an update to my sample demonstrating how to use the AJAX Control Toolkit's dynamic population functionality with a data-bound ModalPopup. Someone asked privately what the C# page method would look like in VB, so I figured I'd post a small follow-up to show the straightforward translation to VB.
Here's the original C# code for reference:
Translating that to VB is largely a matter of changing the syntactic elements from their C# versions to their VB versions. So "[" becomes "<", "}" becomes "End Function", and so on... Two things that tripped me up because I don't regularly use VB were the translation of the hexadecimal prefix "0x" to "&H" and the translation of "static" to "Shared" - but a quick look at the online documentation for VB sorted me out on both counts. After a short while, I ended up with this:
I completed the translation by changing the sample page's Page/Language property from "C#" to "VB", ran the sample page, and verified that it worked just like it did before. Of course! :)
Just a short while ago we made available the 61121 release of the AJAX Control Toolkit. I'd barely finished posting the release bits to CodePlex and was still in the process of verifying them when I saw that we'd already had our first eight customer downloads. Wow, those people must really want the latest stuff! :)
The 61121 release was all about addressing some of the biggest pain points for our customers. Of particular note were two workarounds for ASP.NET AJAX Beta 2 issues:
In addition to those two "big ticket" items, we also fixed a handful of other issues, most of which we chose based on customer feedback and work item voting on CodePlex. (Voting is a fairly recent addition - have a look at how it focuses attention on issues that are important to the community!). The other fixes in the 61121 release address the most popular issues in our CodePlex queue and include fixes for ModalPopup server-side show/hide, ClientState within an UpdatePanel, Accordion pane size updates, multiple DragDrop panels, CommonToolkitScripts, and web.config updates to get things working seamlessly with IIS7.
This being small-scale release, we didn't have time to include any new controls this time around. :( However, that's an explicit goal for an upcoming release which we hope to make available before the end of the year. We've got some neat stuff in the prototype stage and it'll be great to get some of it polished and released to the world!
Recall that you can sample any of the controls right now (no install required). Then you can browse the project web site, download the latest Toolkit, and start creating your own controls and/or contributing to the project!
If you have any feedback, please share it with us on the support forum (or email me)!
On Monday we made available the 61106 release of the AJAX Control Toolkit. We did this in parallel with the release of ASP.NET AJAX v1.0 Beta 2 in order to accommodate some breaking changes introduced in that release. As such, we did not make any functional changes to the Toolkit in the 61106 release, though we did take the opportunity to fix one or two small bugs that we'd found.
