user-controls

问题 When starting to work with WPF UserControls, I stumbled upon several ways to bind content of a UserControl to one of its properties. Here's example C# code for my control: public sealed partial class MyUserControl : UserControl { public MyUserControl() { InitializeComponent(); } public static readonly DependencyProperty TheTextProperty = DependencyProperty.Register("TheText", typeof (string), typeof(MyUserControl), new FrameworkPropertyMetadata(0, FrameworkPropertyMetadataOptions.

问题 I have a complex Windows Forms GUI program that has a lot of automated control generation and manipulation. One thing that I need to be able to do is add a custom UserControl to a newly instatiated TabPage. However, when my code does this I get automatic resizing events that cause the formatting to get ugly.

问题 At work I have several pages, each with buttons in the same places, and with the same properties. Each page also has minor differences. To that end, we created a userControl Template and put all the buttons in it, then applied that user control to all the pages. However, now it's rather hard to access the buttons and modify them from each page's xaml, because they are inside a UserControl on the page..... How do I elegantly access the buttons from each page? What I've tried: Currently, we

A button for showing opnefiledialog An openfiledialog I have added an object tag to the html page with the class id and all that. <OBJECT id="myControl1" name="myControl1" classid="ActiveXUploadFile.dll#ActiveXUploadFile.FileUpload" width=288 height=300></OBJECT> The namespace is ActiveXUploadFile and class name is FileUpload.

问题 More specifically, what do I need to know about doing this in Visual Studio 2008 that's different from VS2005? I have found a decent number of references for doing this kind of thing in VS2005, such as http://webproject.scottgu.com/CSharp/usercontrols/usercontrols.aspx Techniques For Distributing ASP.NET User Controls Across Projects http://weblogs.asp.net/scottgu/archive/2005/08/28/423888.aspx http://support.microsoft.com/kb/324785 but even the Microsoft reference doesn't seem to say much

问题 My user control context menu visibility can't bind a dependency property. Any idea?

问题 I have a animation defined in XAML (as a UserControl) that essentially switches between two images every second: <UserControl x:Class="KaleidoscopeApplication.Controls.RemoteAnimation" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Loaded="RemoteAnimation_Loaded" Unloaded="RemoteAnimation_Unloaded"> <Grid Canvas.Left="500" Canvas.Top="84"> <Grid.Triggers> <EventTrigger RoutedEvent="Grid.Loaded"> <BeginStoryboard>
