示例

以下示例创建 ，DataGridTextBoxColumn并将其添加到 的 。GridColumnStylesCollectionDataGrid 若要运行此代码示例，请将其粘贴到具有 DataGrid 命名 dataGrid1 的窗体中，并从 的 Form构造函数调用它。

private:
   void AddColumn()
   {
      DataTable^ myTable = gcnew DataTable;
      
      // Add a new DataColumn to the DataTable.
      DataColumn^ myColumn = gcnew DataColumn( "myTextBoxColumn" );
      myColumn->DataType = System::Type::GetType( "System::String" );
      myColumn->DefaultValue = "default string";
      myTable->Columns->Add( myColumn );
      
      // Get the CurrencyManager for the DataTable.
      CurrencyManager^ cm = dynamic_cast<CurrencyManager^>(this->BindingContext[ myTable ]);
      
      // Use the CurrencyManager to get the PropertyDescriptor for the new column.
      System::ComponentModel::PropertyDescriptor^ pd = cm->GetItemProperties()[ "myTextBoxColumn" ];
      DataGridTextBoxColumn^ myColumnTextColumn;
      
      // Create the DataGridTextBoxColumn with the PropertyDescriptor.
      myColumnTextColumn = gcnew DataGridTextBoxColumn( pd );
      
      // Add the new DataGridColumn to the GridColumnsCollection.
      dataGrid1->DataSource = myTable;
      dataGrid1->TableStyles->Add( gcnew DataGridTableStyle );
      dataGrid1->TableStyles[ 0 ]->GridColumnStyles->Add( myColumnTextColumn );
   }

private void AddColumn()
{
     DataTable myTable= new DataTable();
 
     // Add a new DataColumn to the DataTable.
     DataColumn myColumn = new DataColumn("myTextBoxColumn");
     myColumn.DataType = System.Type.GetType("System.String");
     myColumn.DefaultValue="default string";
     myTable.Columns.Add(myColumn);
     // Get the CurrencyManager for the DataTable.
     CurrencyManager cm = (CurrencyManager)this.BindingContext[myTable];
     // Use the CurrencyManager to get the PropertyDescriptor for the new column.
     PropertyDescriptor pd = cm.GetItemProperties()["myTextBoxColumn"];
     DataGridTextBoxColumn myColumnTextColumn;
     // Create the DataGridTextBoxColumn with the PropertyDescriptor.
     myColumnTextColumn = new DataGridTextBoxColumn(pd);
     // Add the new DataGridColumn to the GridColumnsCollection.
     dataGrid1.DataSource= myTable;
     dataGrid1.TableStyles.Add(new DataGridTableStyle());
     dataGrid1.TableStyles[0].GridColumnStyles.Add(myColumnTextColumn);
 }

Private Sub AddColumn()
    Dim myTable As New DataTable()
    
    ' Add a new DataColumn to the DataTable.
    Dim myColumn As New DataColumn("myTextBoxColumn")
    myColumn.DataType = System.Type.GetType("System.String")
    myColumn.DefaultValue = "default string"
    myTable.Columns.Add(myColumn)
    ' Get the CurrencyManager for the DataTable.
    Dim cm As CurrencyManager = CType(Me.BindingContext(myTable), CurrencyManager)
    ' Use the CurrencyManager to get the PropertyDescriptor for the new column.
    Dim pd As PropertyDescriptor = cm.GetItemProperties()("myTextBoxColumn")
    Dim myColumnTextColumn As DataGridTextBoxColumn
    ' Create the DataGridTextBoxColumn with the PropertyDescriptor.
    myColumnTextColumn = New DataGridTextBoxColumn(pd)
    ' Add the new DataGridColumn to the GridColumnsCollection.
    dataGrid1.DataSource = myTable
    dataGrid1.TableStyles.Add(New DataGridTableStyle())
    dataGrid1.TableStyles(0).GridColumnStyles.Add(myColumnTextColumn)
End Sub

注解

类 DataGridTextBoxColumn 派生自 abstract 类 DataGridColumnStyle。 在运行时， 承载 DataGridTextBoxColumn 一个 DataGridTextBox 允许用户编辑文本的控件。

添加到 类的特殊属性包括 Format、 和 HideEditBox。 这些属性允许访问托管 DataGridTextBox 控件及其属性，并设置显示值的格式。

如果数据源是包含DataTableDataColumn的对象，DataType应将 的 DataColumn 属性设置为可在文本框控件中以逻辑方式编辑的数据类型。 以下数据类型自动与 DataGridTextBoxColumn ：Byte、、DateTime、Decimal、DoubleInt16、Int32、、Int64、UInt16、UInt64UInt32Single、 和 String关联。
