TemplateColumn.EditItemTemplate 속성

정의

편집을 위해 TemplateColumn 개체에서 선택한 항목을 표시하기 위한 템플릿을 가져오거나 설정합니다.

public:
 virtual property System::Web::UI::ITemplate ^ EditItemTemplate { System::Web::UI::ITemplate ^ get(); void set(System::Web::UI::ITemplate ^ value); };
[System.ComponentModel.Browsable(false)]
[System.Web.UI.PersistenceMode(System.Web.UI.PersistenceMode.InnerProperty)]
[System.Web.UI.TemplateContainer(typeof(System.Web.UI.WebControls.DataGridItem))]
public virtual System.Web.UI.ITemplate EditItemTemplate { get; set; }
[<System.ComponentModel.Browsable(false)>]
[<System.Web.UI.PersistenceMode(System.Web.UI.PersistenceMode.InnerProperty)>]
[<System.Web.UI.TemplateContainer(typeof(System.Web.UI.WebControls.DataGridItem))>]
member this.EditItemTemplate : System.Web.UI.ITemplate with get, set
Public Overridable Property EditItemTemplate As ITemplate

속성 값

ITemplate

ITemplate에서 편집하는 항목을 표시하기 위한 템플릿을 포함하는 TemplateColumn 구현 개체입니다. 기본값은 null로, 이 속성이 설정되지 않았음을 나타냅니다.

특성

예제

다음 코드 예제를 사용 하는 방법에 설명 합니다 EditItemTemplate 속성에서 편집 중인 항목의 모양을 제어 하는 TemplateColumn 개체입니다.

설명

사용 합니다 EditItemTemplate 속성에서 편집을 위해 선택한 항목의 모양을 제어 하는 TemplateColumn 개체입니다. 열에 항목이 렌더링 되는 방법을 정의 하는 템플릿을 만들어 모양을 지정 됩니다. 편집을 위해 선택한 항목에 대 한 서식 파일을 지정 하려면 먼저 배치 열고 닫는 <EditItemTemplate> 을 열고 닫는 태그 사이 <TemplateColumn> 요소입니다. 그런 다음 열기 및 닫기 사이 항목의 모양을 제어 하는 콘텐츠를 나열할 수 있습니다 <EditItemTemplate> 태그입니다. 으로 설정할 수 있는 보다 복잡 한 템플릿에서 다른 컨트롤을 포함 하 여 또는 콘텐츠를 일반 텍스트로 간단할 수 있습니다.
