HasErrors Property

DataSet.HasErrors Property

Gets a value indicating whether there are errors in any of the DataTable objects within this DataSet.

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

'Declaration
<BrowsableAttribute(False)> _
Public ReadOnly Property HasErrors As Boolean
'Usage
Dim instance As DataSet 
Dim value As Boolean 

value = instance.HasErrors

Property Value

Type: System.Boolean
true if any table contains an error;otherwise false.

Each DataTable in a DataSet also has a HasErrors property. Use the HasErrors property of the DataSet first, to determine if any table has errors, before checking individual DataTable objects. If a DataTable has errors, the GetErrors method returns an array of DataRow objects containing the errors.

The following example uses the HasErrors property to determine whether a DataSet object contains errors. If so, the errors for each DataRow in each DataTable are printed.

Private Sub CheckForErrors()
    If Not DataSet1.HasErrors Then
        DataSet1.Merge(DataSet2)
    Else
       PrintRowErrs(DataSet1)
    End If 
End Sub 

Private Sub PrintRowErrs(ByVal dataSet As DataSet)
    Dim row As DataRow
    Dim table As DataTable
    For Each table In  dataSet.Tables
       For Each row In table.Rows
          If row.HasErrors Then
             Console.WriteLine(row.RowError)
          End If 
       Next 
    Next 
End Sub
