DataTable.GetErrors Method

Gets an array of DataRow objects that contain errors.

Namespace:  System.Data
Assembly:  System.Data (in System.Data.dll)

'Declaration
Public Function GetErrors As DataRow()

Return Value

Type: System.Data.DataRow()
An array of DataRow objects that have errors.

Returns the list of DataRow objects that have RowError set. For example, errors can occur when calling Update with ContinueUpdateOnError set to true. Do not invoke AcceptChanges on the DataTable until you resolve all errors and resubmit the DataSet for updating.

The following example uses the GetErrors method to return an array of DataRow objects that have errors.

Private Sub PrintAllErrs(ByVal dataSet As DataSet)
    Dim rowsInError() As DataRow
    Dim table As DataTable  
    Dim i As Integer 
    Dim column As DataColumn
    For Each table In dataSet.Tables
       ' Test if the table has errors. If not, skip it. 
       If table.HasErrors Then 
          ' Get an array of all rows with errors.
          rowsInError = table.GetErrors()
          ' Print the error of each column in each row. 
          For i = 0 To rowsInError.GetUpperBound(0)
             For Each column In table.Columns
                Console.WriteLine(column.ColumnName, _
                rowsInError(i).GetColumnError(column))
             Next 
             ' Clear the row errors
          rowsInError(i).ClearErrors
          Next i
       End If 
    Next 
End Sub
