问题 Jumping into the world of WPF custom controls, and was wondering what the best way to design a HexGrid control would be? Think your favorite table-top war game; or, equally likely, your favorite video game that steals the design from a proud history of table-top war games. The underlying model exposes one significant method, as a part of a Map class: Hex GetHex(int x, int y, int z)*; Hex contains all relevant data (at the moment, a Terrain enumeration that maps 1:1 to a background color;

问题 Every ItemsControl has its content stored in Panel right ? 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 ? For example ListView called LView from above code sample? I cannot use Name property or x:Name ,

问题 I have a Xamarin forms application. It has a page. That page has a listview. The listviews is bind to a sourcelist. What I want is to decide what custom control to use based on a specific property that each item in the list has. How can I achieve this? It is also required that the custom control binds to values from the list. I tried the following: <ContentView Content="{Binding IsPriority, Converter={StaticResource RoadIndicatorBackgroundValueConverter}}" ControlText="{Binding TowingOrder

问题 As the title says, I would like to move the window only when the user will drag it from a portion of the client area. This will be an imitation of the normal caption bar movement and it's because my form is custom and it doesn't have any title or caption bars. At the moment, I use the code as follows: ... case WM_NCHITTEST: return HTCAPTION; and that works fine for making the user able to move the window no matter where he drags from. I would like to limit this possibility (only the top of

问题 My goal is to create a custom TextBlock control that has a new dependency property, SearchText. This property will contain a regular expression. All occurrences of this regular expression in the text of the TextBlock will be highlighted using a custom style (another DP). My current implementation involves clearing all of the Inline objects in the TextBlock's InlineCollection. I then fill the TextBlock with runs for unhighlighted text and runs for highlighted text with the style applied (this

问题 I'm creating a custom control (e.g custom LookUpEdit) and I'm wondering if I can generate code (e.g EditValueChanged event in form.cs file or some rows of code e.g in Form_Load event) automatically while I drag and drop this control inside a form designer, giving this way to any developer the opportunity to easily see and extend this code if he/she wants. My question is: How to generate code or events automatically in a form (form.cs) when you drag-drop a custom control from the toolbox at
