DataGridTextBoxColumn.Format 属性

获取或设置指定格式化文本的方法的一个或多个字符。

**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 Format As String
用法
Dim instance As DataGridTextBoxColumn
Dim value As String

value = instance.Format

instance.Format = value

public string Format { get; set; }

public:
property String^ Format {
    String^ get ();
    void set (String^ value);
}

/** @property */
public String get_Format ()

/** @property */
public void set_Format (String value)

public function get Format () : String

public function set Format (value : String)

属性值

指定格式化文本的方法的一个或多个字符。

备注

Format 属性指定值在列中显示的方式。例如，将该属性设置为“c”以指定值将被格式化为本地货币。使用计算机的 CultureInfo 来确定实际货币格式。在更改数据时，值将自动取消格式变成本机类型。

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。

您应用的格式应适用于数据类型。例如，如果数据实际为数字，则请使用数字格式字符串之一。

通过将 FormatInfo 属性设置为用对应区域性 ID 构造的新的 CultureInfo 实例，可以更改 DataGridTextBoxColumn 的 CultureInfo。

若要设置应用程序的 CultureInfo，请将 Application 对象的 CurrentCulture 属性设置为用对应区域性 ID 构造的新的 CultureInfo 实例。

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.

   ' 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

   DataGridTextBoxColumn myGridTextBoxColumn =

   GridColumnStyles["OrderAmount"];
   myGridTextBoxColumn.FormatInfo = ItalyCultureInfo;

        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";
   }

    /* 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";
}
