Hi, I was just poking around a bit in WPF and wanted all elements on my Window to share the same margin. I found that all Controls that are capable of having a margin derive from FrameworkElement so I tried the following: <Window.Resources> <Style TargetType="{x:Type FrameworkElement}"> <Setter Property="Margin" Value="10" /> </Sty...

I've seen two threads here about TDI & C#. Both of them didn't really answer the questions I have ... Since TDIs are pretty much like a standard nowadays, I can hardly imagine, that I have to buy a special control (like AvalonDock or SandDock). This must be possible with built in the tab-control(?) somehow! I don't need special feature...
Hi, I think I am stupid. I searched now for 15 minutes, and found several different solutions for scrolling on datagrids, but none seems to work for me. I am using WPF with .NET 3.5 and the WPF Toolkit DataGrid. My grid gets updated when my observable collection changes, works perfectly. Now, my DataGrid is located inside a normal Grid ...

If I draw a rectangle and "select it" RenderSize returns proper Size for it, but if Line is selected RenderSize returns Size which has Width set as Line.X2, and Height set as Line.Y2. For example: Line begins at X1 = 50, Y1 = 50, ends at X2 = 13...

Is there an easy way in WPF/XAML to toggle between two types of controls in the same position in a panel? I'm wondering if there are alternatives to toggling visibilities. In my application I have several checkboxes that are used to configure a bit field (the checkboxes toggle individual bits on or off). Sometimes it is easier for the u...
If you use the DelegateCommand in the MVVM Template and build menus dynamically as in the code below, then the DelegateCommand will not fire when the user clicks on the icon area on the MenuItem. Is there anyway to either fix this or make the icon area (to the left of the header) disappear? MainView.xaml: <Window x:Class="TestMenuMvvm...
