Strange behavior with Silverlight when showing modal dialogs in SharePoint
Recently I have been working seriously on integrating Silverlight applications in SharePoint. I already have some experience with SharePoint but with my everyday work I discover more and more “features” of that system.
Everything started with a scenario I had to implement within SharePoint and ended up to be related just to Silverlight. So, my scenario involves creating a small Silverlight application, which is displayed within a web part. This application requires showing a modal dialog, which hosts another application. As my web part may be placed in small space, I preferred to use SharePoint’s dialog feature instead of using ChildWindow. Those two Silverlight applications (the one in the web part and the one in the dialog) communicate via local message infrastructure, which Silverlight provides.
