A Regex is needed to extract the group-values. What is easiest and most efficient way to turn this file's lines into a collection of Line objects? Order of this

问题 for everyone, I found different problems with WPF, the TabControl and the DataGrid. Especially if the TabControl ItemsSource is bound. Problems i found: Selection in DataGrid is not visible after switch Tabs back and forth DataGrid looses sorting on tab switch (SortDescriptions of CollectionView.GetDefaultCollection is cleared on unload) if a DataGrid cell has focus (is in edit mode) and you click on another tab, two things can happen: 1.) the bound object will not be updated; 2.) if the

问题 I have a WCF service and am hosting it in a Windows Service. I tried to add a reference for the service from a Windows Form client built on .NET 2.0.

Now I add the basicHttpBinding and repeat the same steps: And now I can see the classes for the web service. My senior colleague insist that setting the

问题 I create a Datetime object with Datetime.Now and I have this as a property of a class. When I bind this to a grid view: <GridViewColumn Header="Date" Width="120" DisplayMemberBinding="{Binding transaction_date1, StringFormat=HH:mm}" /> The result is always 00:00.

I think that the StringFormat in this case gets the hour and minute from the Date object within the Datetime object
