Insted of Hiding the row you can avoid fetching this rows.... just add the where clause in your select command

..... where Aktiv_Personal!=1 .....

Try to filter in the query it self, for suppose the query is like this,

VB

SELECT [Name],[Vorname]," +
                " [Account Nr],[Phone Nr]" +
  " ,[EMail],[Aktiv_Personal] " +
  " FROM Worker where [Aktiv_Personal]=true order by (Name)"

or else in the code you can identify the bit datatype is boolean only.

Hope it will solve.

Thx Guy but,

i find now in the book (visual C# 2010) a possibility to do it without useing my query
like this.

C#

DataView dv = ds.Tables[0].DefaultView;
dv.RowFilter = "Aktiv_Personal = (0)";/*hier is important to write zero in bracket (0) because of Bit Type. But finally i think u are Right it's the same with the Query*/
Dgrid_MitarbeiterAnsicht.DataSource = dv;
