GridView 동적 바인딩 열

GridView1.DataSource = BLL.GetDataItem();//    
        //    GridView      ：
        //GridView1.Columns.RemoveAt(1); 
        //     GridView     ：
        //           
        BoundField column = new BoundField();
        column.HeaderText = "   ";
        //column.SortExpression = "date1";//       
        column.DataField = "date1";//      （    ）
        //       GridView
        //GridView1.Columns.Add(column);
        //----         
        GridView1.Columns.Insert(1, column);//      (      )
        GridView1.DataBind();

sq 조회 l에서 모든 데이터를 조회할 때 이 방법으로 동적 귀속을 하면 됩니다.Insert 방법을 사용하여 동적 열을 삽입하면 GridView의 컨트롤이 비워지고 직접 귀속된 Text 값만 남습니다. GridView의 Enable ViewState를False로 설정합니다.
상례는 BoundField로 집합에 가입하는 것이다.GridView에 TemplateField를 동적으로 추가하려면 새 TemplateField를 만들고 적절한 템플릿을 정의한 다음 집합Columns에 TemplateField를 추가해야 합니다.
