示例

以下示例创建一个新 CultureInfo 对象，并将其分配给 FormatInfo 对象的属性 DataGridTextBoxColumn 。 该示例还将 Format 属性设置为“c”，以指定列应将值显示为货币。

private:
   void ChangeColumnCultureInfo()
   {
      /* Create a new CultureInfo Object* using the
        the locale ID for Italy. */
      System::Globalization::CultureInfo^ ItalyCultureInfo = gcnew CultureInfo( 0x0410 );
      
      /* Cast a column that holds numeric values to the
        DataGridTextBoxColumn type, and set the FormatInfo
        property to the new CultureInfo Object*. */
      DataGridTextBoxColumn^ myGridTextBoxColumn =
         dynamic_cast<DataGridTextBoxColumn^>(myDataGrid->TableStyles[ "Orders" ]->
         GridColumnStyles[ "OrderAmount" ]);
      myGridTextBoxColumn->FormatInfo = ItalyCultureInfo;
      myGridTextBoxColumn->Format = "c";
   }

private void ChangeColumnCultureInfo(){
   /* Create a new CultureInfo object using the 
   the locale ID for Italy. */
   System.Globalization.CultureInfo ItalyCultureInfo= 
   new CultureInfo(0x0410);
     
   /* Cast a column that holds numeric values to the   
   DataGridTextBoxColumn type, and set the FormatInfo
   property to the new CultureInfo object. */
   DataGridTextBoxColumn myGridTextBoxColumn = 
   (DataGridTextBoxColumn) myDataGrid.TableStyles["Orders"].
   GridColumnStyles["OrderAmount"];
   myGridTextBoxColumn.FormatInfo = ItalyCultureInfo;
   myGridTextBoxColumn.Format = "c";
}

Public Class Form1:Inherits Form
private myDataGrid as DataGrid    
    Public Shared Sub Main()
        Dim t As New Form1()
        ' Write a purchase order.
    End Sub
Private Sub ChangeColumnCultureInfo()
   ' Create a new CultureInfo object using the 
   ' the locale ID for Italy. 
   Dim ItalyCultureInfo As CultureInfo = New _
   CultureInfo(&H0410)
   ' Cast a column that holds numeric values to the   
   ' DataGridTextBoxColumn type, and set the FormatInfo
   ' property to the new CultureInfo object. 
   Dim myGridTextBoxColumn As DataGridTextBoxColumn = _
   CType( myDataGrid.TableStyles("Orders"). _
   GridColumnStyles("OrderAmount"), DataGridTextBoxColumn)
   myGridTextBoxColumn.FormatInfo = ItalyCultureInfo
   myGridTextBoxColumn.Format = "c"
End Sub

注解

将 Format 属性设置为其中一个格式字符时，该 DataGridTextBoxColumn 属性使用属性提供的信息 FormatInfo 进一步指定要使用的区域性特定格式。 例如，当 Format 属性设置为货币) 的格式字符“c” (时，可以进一步指定使用里拉符号。 为此，请创建一个具有意大利区域设置 ID 的新 CultureInfo 对象，并将该属性设置为 FormatInfo 新 CultureInfo 对象。

有关设置字符格式的详细信息，请参阅格式设置类型和自定义日期和时间格式字符串。
