hi guys!
Using a DataReader, I populate a Datagrid with results from an SQL SELECT.
On the grid, I see null values as (null). I'd want the grid to write them as an empy string. (i.e. "")
I tried this:
Dim table_style As New DataGridTableStyle
table_style.MappingName = "Rubrica"
table_style.ReadOnly = True
Dim column_style As DataGridColumnStyle
column_style.NullText = ""
table_style.GridColumnStyles.Add(column_style)
dgKharta.TableStyles.Add(table_style)
It gives an error at
column_style.NullText = ""
<<Object reference not set to an instance of an object>>
I tried with New
Dim column_style As New DataGridColumnStyle
But... <<'New' cannot be used on a class that is declared 'MustInherit'>>
Any suggestions?
