            Uvalue = Trim(AuditGrid.Cell(j, ColMark).Text)
            da.UpdateCommand = New OracleCommand("update audit01 set user" & Trim(User) & "='" & Trim(Uvalue) & "' where audit01.rowid='" & Trim(AuditGrid.Cell(j, ColWRowid).Text) & "'")

Answer 1

i have used the following lines of code and it now works perfectly fine...

If AuditGrid.ActiveCell.Row > 0 Then

        Uvalue = Trim(AuditGrid.Cell(AuditGrid.ActiveCell.Row, ColMark).Text)
        strQry = "update audit01 set user" & Trim(User) & "='" & Trim(Uvalue) & "' where rowidtochar( audit01.rowid)='" & AuditGrid.Cell(AuditGrid.ActiveCell.Row, ColWRowid).Text & "'"
        da = New OracleDataAdapter(strQry, con)
        da.Fill(DsMain)
        DsMain.AcceptChanges()
        MsgBox("Record Updated!!")
        AuditGrid.Range(AuditGrid.ActiveCell.Row, ColMark, AuditGrid.ActiveCell.Row, ColMark).DeleteByRow()
    End If
