this i my first post, so i hope i am explaining it correctly, have a datagridview with a textboxcolumn. it is bind to a dataset

my problem is when i update a record wiht more that 350 characters it give me a nullrefference error. the database is updated when i check the physical record but the application crash

here is the function

Private Sub m_maintenanceProcessor_WebsiteUpdated(ByVal sender As Object, ByVal e As Processors.EventArgs) Handles m_maintenanceProcessor.WebsiteUpdated
Dim tempTable As MaintenanceDataSet.WebsitePageDownloadDataTable

Try
If e.Data.Contains("ModifiedRows") = False Then Exit Sub
tempTable = CType(e.Data("ModifiedRows"), MaintenanceDataSet.WebsitePageDownloadDataTable)
If tempTable.Rows.Count > 0 Then
RemoveHandler maintenanceDataGridView.RowValidated, AddressOf maintenanceDataGridView_RowValidated
Processor.Data.WebsitePageDownload.LoadingTable = True
Processor.Data.WebsitePageDownload.Merge(tempTable, False)
Processor.Data.WebsitePageDownload.LoadingTable = False
Processor.Data.WebsitePageDownload.RejectChanges()
AddHandler maintenanceDataGridView.RowValidated, AddressOf maintenanceDataGridView_RowValidated


Processor.Data.WebsitePageDownload.Merge(tempTable)

'For Each row As DataRow In tempTable.Rows
' If row.RowError IsNot Nothing AndAlso row.RowError.Length > 0 Then
' MsgBox(row.RowError)
' End If

' ' MsgBox(row("URL").ToString)

'Next

'MsgBox(Processor.Data.WebsitePageDownload.Columns("defaultstatusid").MaxLength)
Processor.Data.WebsitePageDownload.AcceptChanges()
End If
Catch ex As Exception
MsgBox(ex.Message.ToString)
End Try
tempTable = Nothing

Me.StatusMessage = String.Empty

End Sub


error gets thrown on acceptchanges
