Re: dotConnectPostgreSQL problem with null value
ADO.NET level:
If there is NULL in the database column, the provider returns NULL. If it is an empty string in the database, the provider returns an empty string.
DataGridView level:
You can control the way how to represent the NULL value via DataGridViewCellStyle.NullValue.
