We can specify the panel to be used in XAML like this: <ListView Name="LView"> <ListView.ItemsPanel> <ItemsPanelTemplate > <StackPanel/> </ItemsPanelTemplate> </ListView.ItemsPanel> </ListView> My question is how to get instance of Panel that is used in the ItemsPanel property (of type ItemsPanelTemplate ) of the particular ItemsControl ?

Settings and Controls In the previous section of our tutorial we have just built a simple sampling widget. Let us now make this widget a bit more useful, by allowing a user to set the proportion of data instances to be retained in the sample. Say we want to design a widget that looks something like this: What we added is an Options box, with a spin entry box to set the sample size, and a check box and button to commit (send out) any change we made in setting. If the check box with “Commit data on selection change” is checked, than any change in the sample size will make the widget send out the

You can identify the control by its name from codebehind as usual. If you want to use it from XAML directly, I would try implementing a custom 'value converter

问题 I'm trying to list and get the content of Edit Controls from an external Window in C++ / Java, unfortunately with no success.

Here the C++ Code: BOOL CALLBACK EnumChildProc(HWND hwnd, LPARAM lParam) { cout <<"----------CHILD------------"<

问题 In Media Player Classic I found a way to jump to a point in a video/audio programmatically, avoiding the Go To... box.
