Przykłady
Poniższy przykład ustawia tekst błędu dla dziesięciu wierszy tabeli wyświetlanej w DataGrid kontrolce.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
Uwagi
Używa HasErrors właściwości, aby najpierw określić, czy DataRow zawiera błędy.Uses the HasErrors property to first determine whether a DataRow contains errors.
