I think I might be going mad because I have loads of strings which are being converted into dates and one pesky little one wont go through.
Code:
"Feb 20 10:36"
and
"Dec 11 14:17"
Are acceptable and parse perfectly using Date.Parse() however...
Code:
"Sep 24 11:25"
Does not.
The error I get is:
The DateTime represented by the string is not supported in calendar System.Globalization.GregorianCalendar.
I have a application which gets info from an external feed where dates are in the format ddMMM. I'm trying to turn them into full date format so I was using DateTime.ParseExact. Which was correctly working out whether it should be 2011 or 2012 . But it is erroring when trying to parse 29FEB (which should be 29 Feb 2012. I can guess why its erroring. But if that correct behaviour is this documented and is there a better alternative? [code]

View 2 RepliesWPF: Display a bool value as Yes / NoI'm writing a WPF program in VB.Net 2010 (.NET 4.0) that uses data binding against a simple class that is an ObservableCollection of another simple class I've written. So far I have a DataGrid that shows the information and I can add and remove items as necessary, but I seem to be stumbling with a fairly basic concept:How do I display data in some way other than the default behaviours that the various DataGrid columns allow?I have a boolean called "reversed" in my original class, let's call it "x". I would like the DataGrid displaying the ObservableCollection of "x" to display "Yes" or "No" under the Reversed column instead of a checkbox that is checked or unchecked (DataGridCheckBoxColumn).
