DataGridView 控制項概觀 (Windows Form)DataGridView Control Overview (Windows Forms)


DataGridView 控制項會取代 DataGrid 控制項並加入其他功能,不過您也可以選擇保留 DataGrid 控制項,以提供回溯相容性及未來使用。The DataGridView control replaces and adds functionality to the DataGrid control; however, the DataGrid control is retained for both backward compatibility and future use, if you choose. 如需詳細資訊,請參閱 Windows Forms DataGridView 和 DataGrid 控制項之間的差異For more information, see Differences Between the Windows Forms DataGridView and DataGrid Controls.

利用 DataGridView 控制項,您可以顯示和編輯許多不同資料來源類型的表格式資料。With the DataGridView control, you can display and edit tabular data from many different kinds of data sources.

將資料系結至 DataGridView 控制項既簡單又直覺,而且在許多情況下,只要設定屬性就可以了 DataSourceBinding data to the DataGridView control is straightforward and intuitive, and in many cases it is as simple as setting the DataSource property. 當您系結至包含多個清單或資料表的資料來源時,請將 DataMember 屬性設定為字串,以指定要系結的清單或資料表。When you bind to a data source that contains multiple lists or tables, set the DataMember property to a string that specifies the list or table to bind to.

DataGridView控制項支援標準 Windows Forms 資料系結模型,因此它會系結至下列清單中所述的類別實例:The DataGridView control supports the standard Windows Forms data binding model, so it will bind to instances of classes described in the following list:

DataGridView控制項支援資料系結至這些介面所傳回之物件的公用屬性,或是介面所傳回之屬性集合的資料系結 ICustomTypeDescriptor (如果在傳回的物件上執行的話)。The DataGridView control supports data binding to the public properties of the objects returned by these interfaces or to the properties collection returned by an ICustomTypeDescriptor interface, if implemented on the returned objects.

一般而言,您會系結至 BindingSource 元件,並將 BindingSource 元件系結至其他資料來源,或以商務物件填入。Typically, you will bind to a BindingSource component and bind the BindingSource component to another data source or populate it with business objects. BindingSource元件是慣用的資料來源,因為它可以系結至各種不同的資料來源,而且可以自動解決許多資料系結問題。The BindingSource component is the preferred data source because it can bind to a wide variety of data sources and can resolve many data binding issues automatically. 如需詳細資訊,請參閱 BindingSource 元件For more information, see BindingSource Component.

DataGridView控制項也可以在 系結模式中使用,而不會有基礎資料存放區。The DataGridView control can also be used in unbound mode, with no underlying data store. 如需使用未系結控制項的程式碼範例 DataGridView ,請參閱 逐步解說:建立未系結的 Windows Forms DataGridView 控制項For a code example that uses an unbound DataGridView control, see Walkthrough: Creating an Unbound Windows Forms DataGridView Control.

控制項可高度設定且可延伸 DataGridView ,而且可提供許多屬性、方法和事件來自訂其外觀和行為。The DataGridView control is highly configurable and extensible, and it provides many properties, methods, and events to customize its appearance and behavior. 當您想要 Windows Forms 應用程式顯示表格式資料時,請考慮在 DataGridView 其他專案之前使用控制項 (例如 DataGrid) 。When you want your Windows Forms application to display tabular data, consider using the DataGridView control before others (for example, DataGrid). 如果您要顯示唯讀值的小型方格,或如果您要讓使用者編輯含有數百萬筆記錄的資料表,此 DataGridView 控制項將會提供您可立即使用的程式化、記憶體效益的解決方案。If you are displaying a small grid of read-only values, or if you are enabling a user to edit a table with millions of records, the DataGridView control will provide you with a readily programmable, memory-efficient solution.
