Each of the individual user rows is its own UserControl/XtraUserControl, laid out in a FlowLayoutPanel. The problem I have is with perfo...
Hi all, I guess I'm a bit stuck on the mechanism of WPF DataBinding. Up to now I've thought of it as this : Any target of a DataBinding has to be a DependencyProperty.Keeping that in mind, I designed a very simple button-based UserControl like the following (boiled down to the most necessary parts): XAML <Button x:Class="MyNamespace.I...

I'm trying to confirm a binding behavior I believe I have observed, but I'm not exactly sure of. My original understanding was that a UserControl was sort of a black box, where if you wanted to share information back and forth with the controls contained within, you had to (1) use the DataContext or (2) define them on the surface of the...

I'm a beginner in the black art of ASP .NET development, so forgive me if this is a stupid question. After a bit of googling, and reading though (some of...) ASP .NET 3.5 Unleashed, I've yet to find a way of doing what I want - which usually either means I'm trying to do something stupid, or it's so obvious I've missed it :) I'm creati...
