问题 This is what I'm trying to accomplish: I want to have a canvas that supports dragging and dropping arbitrary data in the style of Microsoft Visio. I've found this link that does that: http://www.codeproject.com/KB/WPF/WPFDiagramDesigner_Part1.aspx However, I also want to hydrate the canvas at run-time.

问题 I have several combo boxes in a Scheduling module that all have dropdown lists based on an "Active" field. public class Project { public int ProjectID { get; set; } public int ProjectTitle { get; set; } public bool Active { get; set; } } <ComboBox Name="ProjectComboBox" ItemsSource="{Binding AllProjects}" SelectedItem="{Binding Project, Mode=TwoWay}"> </ComboBox> The calendar's editing form must always display legacy information in its combo boxes, even if a particular item in a combo list

问题 I have a simple problem with an animated binded property. Here is a simple example to illustrate it : ViewModel : public class ViewModel { private double myProperty; public double MyProperty { get { return myProperty; } set { myProperty = value; /* Break point here */ } } public ViewModel() { MyProperty = 20; } } MyControl : public class MyControl : Button { protected override void OnClick() { base.OnClick(); Height = ActualHeight + 20; } } MyAnimatedControl : public class MyAnimatedControl :
