Changing alignment of column in datagrid02 Jun 2004 20:05 GMT2
I thought I had done this before, but I'm apparently overlooking something.

As I figured out, the recomended way to cancel editing of a column, or
deletion of a row is to create an event handler for ColumnChanging or
RowDeleting events, and to throw your own exception. Well, I did just

I am using a DataTable (dt) based on a SQL Server table containing a column of type varbinary(50) named descriptor. The DataTable column for this field is base64Binary, which seems to map to System.byte[]. I then defined a DataView (dv) with dv.Sort="descriptor". I find that if I ...
