问题 Is it possible to change where a control is placed in a grid from code-behind? For example, if I have a Button in Grid.Row="1", can I change that to Grid.Row="0" from code-behind? 回答1: Yes. Just go: Grid.SetRow(button,0); where button is the element to change. 来源： https://stackoverflow.com/questions/3785572/wpf-change-the-place-of-a-control-in-a-grid-in-code-behind

问题 I made Button in Xaml. I would like to fire MouseDown event: MouseDown="Button_MouseDown_1" I implemented this method in codeBehind, but it doesn't work.

Seba. 回答1: The Button element itself is handling the mouse down event before your event handler gets called - meaning your event handler wont get called. More than likely what you're actually wanting to implement is the Click event

问题 While answering this question I noticed that I have never come across any property which is not a dependency property (WPF Controls, no 3rd party controls). Although, when I started with WPF I remember reading somewhere that "more then 90% of properties of WPF controls are dependency properties". Can anyone give examples/links of CLR properties in WPF controls and why it's so? Update: Came across this lecture: http://www.miszalok.de/Lectures/L17_WPF/C4_DependencyProperties

问题 I have a hopefully trivial question. Currently, my company works with a rather obscure language (SyngergyDE) and we need to call a SilverLight application inside our product. Unfortunately, this obscure 3rd party language only (currently) supports the opening of WPF screens. So with that said, I thought I'd develop a small WPF user control that contains a "WebBrowser" control and navigate to the silverlight application's URI. This works fine, and I'm able to see the SL application. Here is my

问题 It seems that the WPF TabControl doesn't support the ability to cancel a selection change, since there is no SelectionChanging() event, only a SelectionChanged event. Has anyone figured out a way to do this? The only way I have found is to attach to the PreviewMouseLeftButtonDown() event on each TabItem and set e.Handled to true if I don't want that particular page selected. This seems to work but is clunky. 回答1: I found a way do do this using a style for a TabItem and then binding the
