cmd.CommandType = CommandType.Text

cmdUpdate.CommandType = CommandType.Text

cmdUpdate.CommandText = "Update BigOne Set Rezultat=? where ID=?"

cmdUpdate.Parameters.Add("Rezultat", OleDb.OleDbType.Char, 30, "Rezultat")

cmdUpdate.Parameters.Add("ID", OleDb.OleDbType.Integer, 6, "ID")

cmdUpdate.Parameters("ID").SourceVersion = DataRowVersion.Original

'todo: vidi ovu komandu

da.SelectCommand = cmd

da.UpdateCommand = cmdUpdate

cmd.CommandText = "SELECT sections.ID, Analize.Name as Analiza,
BigOne.Rezultat FROM BigOne INNER JOIN Analize ON BigOne.IDAnalize =
Analize.ID INNER JOIN Sections ON Analize.IDSekcije = Sections.ID WHERE
BigOne.BrojProtokola Like '" & txtBroPro.Tekst.Trim & "'"

da.Fill(ds, "Sekcije")

and then use dataview object to filter data and fill various datagrids on my
form. Datagrids aro on diferent TabPages. When i click on btnOK whit this
