Examples

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

private void SetRowErrors(DataTable table)
{
 // Set error text for ten rows.
 for(int i = 0; i < 10; i++)
 {
 // Insert column 1 value into each error.
 table.Rows[i].RowError = "ERROR: "
 + table.Rows[i][1];
 }
 // Get the DataSet for the table, and test it for errors.
 DataSet dataSet = table.DataSet;
 TestForErrors(dataSet);
}

private void TestForErrors(DataSet dataSet)
{
 // Test for errors. If DataSet has errors, test each table.
 if(dataSet.HasErrors)
 {
 foreach(DataTable tempDataTable in dataSet.Tables)
 {
 // If the table has errors, then print them.
 if(tempDataTable.HasErrors)
 PrintRowErrs(tempDataTable);
 }
 // Refresh the DataGrid to see the error-marked rows.
 dataGrid1.Refresh();
 }
}

private void PrintRowErrs(DataTable table)
{
 foreach(DataRow row in table.Rows)
 {
 if(row.HasErrors)
 {
 Console.WriteLine(row.RowError);
 }
 }
}

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: " & _
 table.Rows(i)(1).ToString()
 Next
 ' Get the DataSet for the table, and test it for errors.
 Dim dataSet As DataSet = table.DataSet
 TestForErrors(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 
 PrintRowErrs(tempDataTable)
 End If
 Next
 ' Refresh the DataGrid to see the error-marked rows.
 DataGrid1.Refresh()
 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
 Console.WriteLine(row.RowError)
 End If
 Next
End Sub

Remarks

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