DynamicDataExtensions.FindFieldTemplate(Control, String) 方法

定義

傳回在指定之控制項的命名容器中所指定資料行的欄位樣板。Returns the field template for the specified column in the specified control's naming container.

public:
[System::Runtime::CompilerServices::Extension]
 static System::Web::UI::Control ^ FindFieldTemplate(System::Web::UI::Control ^ control, System::String ^ columnName);
public static System.Web.UI.Control FindFieldTemplate (this System.Web.UI.Control control, string columnName);
static member FindFieldTemplate : System.Web.UI.Control * string -> System.Web.UI.Control

參數

control
Control

內含控制項。The containing control.

columnName
String

資料行名稱。The name of the column.

傳回

指定之控制項的命名容器中所指定資料行的欄位樣板。The field template for the specified column in the specified control's naming container.

範例

下列範例顯示如何尋找指定資料行名稱的文字方塊控制項。The following example shows how to find the text box control for a specified column name. 例如,動態資料頁面範本會複製到 \DynamicData\CustomPages\ProductDescriptions 資料夾,以提供 AdventureWorksLT 資料庫 ProductDescription 資料表的自訂顯示。In example, the Dynamic Data page templates are copied to the \DynamicData\CustomPages\ProductDescriptions folder to provide a custom display for the ProductDescription table of the AdventureWorksLT database. 插入 .aspx 檔案標記會變更,以加入OnDataBound名為DetailsView1_DataBoundFindDataSourceControl事件處理常式,其中會呼叫方法來尋找文字方塊控制項。The Insert.aspx file markup is changed to add an OnDataBound event handler named DetailsView1_DataBound, in which the FindDataSourceControl method is called to find a text box control.
