I tried many methods but change is not saved to database. Could you give me code example please?

Please help.

Me.taSet.Fill(Me.Dsset.tblQuestions) 
Dsset.tblQuestions.Rows(1).BeginEdit() 
Dsset.tblQuestions.Rows(1).Item("ExamID") = "EDITED"
Dsset.tblQuestions.Rows(1).AcceptChanges() 
taSet.Update(Dsset.tblQuestions)

Remove the following line from your code :

Dsset.tblQuestions.Rows(1).AcceptChanges() 

When you call AcceptChanges(), you mark that row as clean (which means this row has not been edited). That is why it does not get upodated.
