collapsed

Hey guyz!

I have a .net 2.0 C# Project. I have a Treeview with 2 Nodes, each of them has many child nodes. When you click on a child node, a PDF is displayed in a webbrowser control depending on the properties of the node. Fine, but the problem is that when both Nodes are expanded, and I click on a child node, the other node gets collapsed! I don't have any code that collapses any node of the treeview, but somehow it happens! I also had a look at the BeforeCollapse Event, but somehow it doesn't fire, alltough the other node collapses!

Can anyone imagine why this happens? I would be very grateful if anyone can teach me how to prevent this happening!

Thank you very much!

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
