Just a quick one: if you have a textbox with a Calendar (extender) from the Ajax Control Toolkit and an associated PopupButtonID which is an image, the calendar won’t close when you click outside the popup. Use an input type=”image”or an ImageButton to solve this problem.
Because we were still using an old Visual Studio 2005 solution which included a Web Site project, it was time to upgrade. We upgraded our Visual Studio 2005 solution to Visual Studio 2010 (and .NET 4.0), converted the Web Site Project to a Web Application Project and then, of course, the AjaxControlToolkit had to follow. I downloaded the latest build from their Codeplex site and updated the references in the different projects. I ran the website, and that’s where things got ugly …
Because I stopped working at Avanade and started my own company (this web site is under construction and in Dutch), I had to buy and install a new laptop. Everything went great and I was up and running in half a day. Or should I say half an evening… 😉
After extending a textbox with a NumberUpDownExtender, which comes with the AJAX Control Toolkit, I recieved the error “the number of fractional digits is out of range”. This happened when debugging my web application and using the extender. When using the web app in non-debug mode, nothing happened. This included the value change ’not happening'.
As I said earlier, we didn’t test our solution to using the ModalPopupExtender in SharePoint in all situations. Today we made a start to do so. To indicate our successrate: we now use window.showModalDialog with some extra pages…
Getting the ModalPopupExtender from the Ajax Control Toolkit to work (decently) in SharePoint was not exactly a walk in the park. With a default SharePoint installation, the modal popup is partly positioned ‘outside’ of the page (you only see the bottom right part of the popup in the top left corner of the browser). Postbacks are not executed or executed poorly and the page gets garbled up. A possible solution for the positioning of the popup is to set the X and Y property of the ModalPopupExtender. Downside is you never know (for sure) if the popup is positioned inside the visible part of the browser because of things like non-maximized browser, different resolutions and so on.
Today we seem to have solved our issues with the ModalPopupExtender in SharePoint. We haven’t tested it in all scenario’s yet, but we’ll get to that. At this point everything looks the way it is supposed to. And it seems to work, too… ;).
