问题 I have a WPF datagrid which works for what I want, but there are two cells in each row which can be edited. Is it possible to place both of these rows into edit mode when the row is edited, then fire the update when the row edit ends/the row loses focus? Currently, after each cell is edit, RowEditEnding fires and the user must wait for the UI to redraw after the commit. The code I'm using is: private bool isManualEditCommit; private void dg_RowEditEnding(object sender,

问题 I have two ListView , each bound to a specific collection in my ViewModel and I want to be able to select only one item globally.

问题 Forgive me if this is a technical issue rather than a software-programming one, but I am having difficulty determining the probable cause here, be it the .NET Framework or something lower level, perhaps graphics hardware. Essentially, no WPF application will run on a second monitor using my Windows 10 Alienware 13 laptop. The same application, on the same monitor, running under my Windows 8 Alienware 15, will work fine. Visual Studio 2015 is a similar case, if there might be a common factor.

问题 I am trying to bind the "IsChecked" property on the ToggleButton to "ModelView.IsEnabled". "ModelView.IsEnabled" is always "false" but somehow the ToggleButton can still show as "Checked". Is there anything wrong with the binding?
