Hi There I've noticed something funny, and was wondering if you can reproduce this or shed any light. I've got a PropertyGrid styled with TreeView + GroupStyle control template using Expanders. When I load a form once, the component displays correctly. Weirdly though, when I create more instances of the same form - the PropertyGrid isn't there any more? If I leave out the GroupStyle template, everything appears to be ok, so I presume it has something to do with this. Strange though that it works once, but only once. I've attached a small project to illustrate. The project needs a reference to the component obviously, and the sample data library. Oh, and I'm using the 20080425 Nightly Build. Regards, Justin.

Hi Justin, This has something to do with the way WPF instantiates inline resources. If you extract your Style declaration to be a separate resource in your ResourceDictionary, and reference it as <GroupStyle ContainerStyle="{StaticResource MyGroupStyle}" />, that fixes the problem. I'm afraid this is a bit of a "cargo cult programming" answer rather than explaining what's happening under the surface to cause the odd behaviour. I've seen this difference between inlined and resource-based objects (e.g. styles and templates) before but haven't delved sufficiently into it to know why it happens or whether there is a way to get the expected behaviour while still keeping the inline declaration. Sorry! |
