Namespace:  System.Data
Assembly:  System.Data (in System.Data.dll)
Public Property RowError As String

Property Value

Type: System.String
The text describing an error.

Uses the HasErrors property to first determine whether a DataRow contains errors.

The following example sets error text for ten rows of a table displayed in a DataGrid control.

Private Sub SetRowErrors(ByVal table As DataTable)
    ' Set error text for ten rows.  
    Dim i As Integer 
    For i = 0 to 10
        ' Insert column 1 value into each error.
        table.Rows(i).RowError = "ERROR: " & _
    ' Get the DataSet for the table, and test it for errors. 
    Dim dataSet As DataSet = table.DataSet
End Sub 

Private Sub TestForErrors(ByVal dataSet As DataSet)
    ' Test for errors. If DataSet has errors,  
    ' test each table. 
    If dataSet.HasErrors
        Dim tempDataTable As DataTable
        For Each tempDataTable in dataSet.Tables
            ' If the table has errors, then print them. 
            If(tempDataTable.HasErrors) Then 
            End If 
        ' Refresh the DataGrid to see the error-marked rows.
    End If 
End Sub 

Private Sub PrintRowErrs(ByVal table As DataTable)
    Dim row As DataRow
    For Each row in table.Rows
       If(row.HasErrors) Then
       End If 
End Sub
