DataGridColumnStyle.PropertyDescriptor 属性

获取或设置 PropertyDescriptor，它确定 DataGridColumnStyle 所显示数据的属性。

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

语法

声明
Public Overridable Property PropertyDescriptor As PropertyDescriptor
用法
Dim instance As DataGridColumnStyle
Dim value As PropertyDescriptor

value = instance.PropertyDescriptor

instance.PropertyDescriptor = value

public virtual PropertyDescriptor PropertyDescriptor { get; set; }

public:
virtual property PropertyDescriptor^ PropertyDescriptor {
    PropertyDescriptor^ get ();
    void set (PropertyDescriptor^ value);
}

/** @property */
public PropertyDescriptor get_PropertyDescriptor ()

/** @property */
public void set_PropertyDescriptor (PropertyDescriptor value)

public function get PropertyDescriptor () : PropertyDescriptor

public function set PropertyDescriptor (value : PropertyDescriptor)

属性值

一个 PropertyDescriptor，它包含有关列的属性的数据。

备注

使用 BindingManagerBase 的 GetItemProperties 方法设置列的 PropertyDescriptor。有关使用 PropertyDescriptor 创建新 DataGridColumnStyle 的示例，请参见 DataGridColumnStyle 构造函数。

示例

下面的代码示例获取 GridColumnStylesCollection 中某列的 PropertyDescriptor。第二个示例使用 PropertyDescriptor 创建一个新的 DataGridColumnStyle。

Private Sub GetPropertyDescriptor()
    Dim pd As PropertyDescriptor
    pd = dataGrid1.TableStyles(0).GridColumnStyles(0).PropertyDescriptor
    Console.WriteLine(pd.ToString())
End Sub 'GetPropertyDescriptor


Private Sub CreateNewDataGridColumnStyle()
    Dim myGridColumnCol As GridColumnStylesCollection
    myGridColumnCol = dataGrid1.TableStyles(0).GridColumnStyles
    ' Get the CurrencyManager for the table you want to add a column to.
    Dim myCurrencyManager As CurrencyManager = CType(Me.BindingContext(ds.Tables("Suppliers")), CurrencyManager)
    ' Get the PropertyDescriptor for the DataColumn of the new column.
    Dim pd As PropertyDescriptor = myCurrencyManager.GetItemProperties()("City")
    Dim myColumn As New DataGridTextBoxColumn(pd)
    myGridColumnCol.Add(myColumn)
End Sub 'CreateNewDataGridColumnStyle

private void GetPropertyDescriptor()
{
    PropertyDescriptor pd;
    pd = dataGrid1.TableStyles[0].GridColumnStyles[0].PropertyDescriptor;
    Console.WriteLine(pd.ToString());
}
 
private void CreateNewDataGridColumnStyle()
{
    GridColumnStylesCollection myGridColumnCol;
    myGridColumnCol = dataGrid1.TableStyles[0].GridColumnStyles;
    // Get the CurrencyManager for the table you want to add a column to.
    CurrencyManager myCurrencyManager = (CurrencyManager)this.BindingContext[ds.Tables["Suppliers"]];
    // Get the PropertyDescriptor for the DataColumn of the new column.
    PropertyDescriptor pd = myCurrencyManager.GetItemProperties()["City"];
    DataGridColumnStyle myColumn = new DataGridTextBoxColumn(pd);
    myGridColumnCol.Add(myColumn);
 }

private:
   void GetPropertyDescriptor()
   {
      PropertyDescriptor^ pd;
      pd = dataGrid1->TableStyles[ 0 ]->GridColumnStyles[ 0 ]->PropertyDescriptor;
      Console::WriteLine( pd );
   }

   void CreateNewDataGridColumnStyle()
   {
      GridColumnStylesCollection^ myGridColumnCol;
      myGridColumnCol = dataGrid1->TableStyles[ 0 ]->GridColumnStyles;
      
      // Get the CurrencyManager for the table you want to add a column to.
      CurrencyManager^ myCurrencyManager = dynamic_cast<CurrencyManager^>(this->BindingContext[ ds->Tables[ "Suppliers" ] ]);
      
      // Get the PropertyDescriptor for the DataColumn of the new column.
      PropertyDescriptor^ pd = myCurrencyManager->GetItemProperties()[ "City" ];
      DataGridColumnStyle^ myColumn = gcnew DataGridTextBoxColumn( pd );
      myGridColumnCol->Add( myColumn );
   }

private void GetPropertyDescriptor()
{
    PropertyDescriptor pd;
    pd = dataGrid1.get_TableStyles().get_Item(0).
        get_GridColumnStyles().get_Item(0).get_PropertyDescriptor();
    Console.WriteLine(pd.ToString());
} //GetPropertyDescriptor

private void CreateNewDataGridColumnStyle()
{
    GridColumnStylesCollection myGridColumnCol;
    myGridColumnCol = dataGrid1.get_TableStyles().get_Item(0).
        get_GridColumnStyles();
    // Get the CurrencyManager for the table you want to add a column to.
    CurrencyManager myCurrencyManager = 
        (CurrencyManager)(this.get_BindingContext().
        get_Item(ds.get_Tables().get_Item("Suppliers")));
    // Get the PropertyDescriptor for the DataColumn of the new column.
    PropertyDescriptor pd = myCurrencyManager.GetItemProperties().
        get_Item("City");
    DataGridColumnStyle myColumn = new DataGridTextBoxColumn(pd);
    myGridColumnCol.Add(myColumn);
} //CreateNewDataGridColumnStyle
