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

参数

control
Control Control Control

包含控件。The containing control.

columnName
String String String

列的名称。The name of the column.

返回

指定控件的命名容器中指定列的字段模板。The field template for the specified column in the specified control's naming container.

示例

下面的示例演示如何查找指定列名称的文本框控件。The following example shows how to find the text box control for a specified column name. 例如,动态数据页模板将复制到 \DynamicData\CustomPages\ProductDescriptions 文件夹,以提供 AdventureWorksLT 数据库的 ProductDescription 表的自定义显示。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. 已更改 Insert .aspx 文件标记以添加OnDataBound名为DetailsView1_DataBound的事件处理程序,在该FindDataSourceControl处理程序中调用方法来查找文本框控件。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.
