问题 My application is implemented by a GridView inside a TreeList . Much to my despair, I discovered that the GridView is very primitive, compared to the widely used DataGrid . I am considering these two options: (1) Somehow, I replace the GridView with a DataGrid (which supports Context Menu). (2) Somehow, I add the Context Menu capability to the existent GridView.

问题 I want to draw a set of 3D-Cubes, each Cube should display a name and also should have its own event handler when the cube is selected. Is it possible to implement it using code behind or xaml binding? 回答1: To draw a 3D cube from code behind I would use the Helix3D toolkit CubeVisual3D.

问题 Assume that I have two WPF windows: window_One and window_Two. window_One has one button. Clicking this button opens window_Two. window_Two contains a User Control. This user control has one button that closes window_Two. How can I achieve this scenario? 回答1: Inside the custom control that you've created.

问题 I have a documentviewer which i used in my wpf project to show xps document reports of having around 600 pages which is working great. But from user point of view i like to show the current page number as a tooltip on my scrollviewer while dragging the scroll stating the current page number in view. Somewhat like in a PDF file like this - I was looking out for some ideas how to implement this. Just a current page number if not possible to show a thumbnail image would be good enough for me. Is
