Hello!

I was able to do a workaround to solve my initial problem of how to dynamicaly create a user-defined mask by using a Converter.

Now I face a new problem in the same area with Sorting dates.

The default format of the date is "yyyy-MM-ddTHH:mm:ss" and I mask it to "dd/MM/yyyy HH:mm:ss" and it works just fine but the Xceed WPF DataGrid column sorting feature fails to sort the column correctly. It doesn't raise any type of error. It simply re-organizes the data in the table in another way but not correctly sorted.

How can I fix this?

Best regards, Gil

Hi Gil,

If your column is of string type, then this could be the same problem as described here:

If that doesn't solve it, then you may have to do some custom sorting and provide a custom sort comparer:

Hello!

I resolved my problem by building from scratch my own custom comparer and associating to all columns of the WPF DataGrid.

Custom comparer class:

public class MyGenericComparer : IComparer



Association:

DataGridCollectionView dgcv = (DataGridCollectionView)TpDataGrid.ItemsSource;
dgcv.ItemProperties.ForEach(z => z.SortComparer = new MyGenericComparer());


Does the WPF DataGrid v3.5 have this sorting problem fixed so I won't have to do this association?

Best regards, Gil
