Question

나는 목록보기와 ItemTemplate을에서 레이블이, 내가

<asp:Label id="GreenDate" runat="server" Text='<%# Eval("NewsDate") %>'></asp:Label> 

텍스트를 설정하지만 난 평가 ("NewsDate")는 데이터 소스에 의해 반환 된 값을 조작하고 새 값을 표시하려면 레이블에. 이벤트에서이 값에 액세스 할 수있는 방법은 무엇입니까?

Answer 1

ItemDataBound을 사용하고이 <%# Eval("NewsDate") %>에 해당하는 DataBinder.Eval(e.Item.DataItem, "NewsDate")을 사용하십시오. 당신이 그 (것)들을 정말 유용 경우

Label lbl = (Label) Item.Controls.FindControlByID("GreenDate"); 

Answer 2

protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e) 
    { 
     if (e.Item.ItemType == ListViewItemType.DataItem) 
     { 
      HtmlTableCell lblpwdHeader = (HtmlTableCell)this.ListView1.FindControl("tdColumn"); 
      HtmlTableCell tdPwdData = (HtmlTableCell)e.Item.FindControl("tdPwd"); 

      if (lblpwdHeader != null) 
      { 
       lblpwdHeader.Visible = false; 
      } 
      if (tdPwdData != null) 
      { 
       tdPwdData.Visible = false; 
      } 
     } 
    }
