DataGridTextBoxColumn.FormatInfo 属性

获取或设置用于确定格式化值的方法的特定区域性信息。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Property FormatInfo As IFormatProvider
用法
Dim instance As DataGridTextBoxColumn
Dim value As IFormatProvider

value = instance.FormatInfo

instance.FormatInfo = value

public IFormatProvider FormatInfo { get; set; }

public:
property IFormatProvider^ FormatInfo {
    IFormatProvider^ get ();
    void set (IFormatProvider^ value);
}

/** @property */
public IFormatProvider get_FormatInfo ()

/** @property */
public void set_FormatInfo (IFormatProvider value)

public function get FormatInfo () : IFormatProvider

public function set FormatInfo (value : IFormatProvider)

属性值

实现 IFormatProvider 接口的一个对象，如 CultureInfo 类。

备注

当将 Format 属性设置为格式化字符之一时，DataGridTextBoxColumn 使用由 FormatInfo 属性提供的信息，来进一步指定要使用的特定区域格式设置。例如，当将 Format 属性设置为格式字符“c”（代表货币）时，可以进一步指定将使用代表里拉的符号。若要实现这一点，请使用意大利的区域设置 ID 创建一个新的 CultureInfo 对象，并将 FormatInfo 属性设置为新的 CultureInfo 对象。

有关设置字符格式的更多信息，请参见 日期与时间格式字符串 和 标准数字格式字符串。

示例

下面的示例创建一个新的 CultureInfo 对象，并将其分配给 DataGridTextBoxColumn 对象的 FormatInfo 属性。该示例还将 Format 属性设置为“c”，以指定列应该将值显示为货币值。

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

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";
}

private:
   void ChangeColumnCultureInfo()
   {

        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(0x410);

    /* 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.get_TableStyles().
        get_Item("Orders").get_GridColumnStyles().
        get_Item("OrderAmount")));

    myGridTextBoxColumn.set_FormatInfo(ItalyCultureInfo);
    myGridTextBoxColumn.set_Format("c");
} //ChangeColumnCultureInfo

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