Gridview 행이 null이거나 객체가 아닙니다.

저는 금액이 0 또는 "" 인 경우 원하는 내용이 Gridview입니다. 송장 생성 버튼을 숨기고 싶습니다. 내가Gridview 행이 null이거나 객체가 아닙니다.

Microsoft JScript runtime error: 'GridExpInfo.Rows[...].Cells.14.style' is null or not an object

으로 오류를 얻고있다

function GridExpInfo_ClientInsert() { 
     for (i = 0; i < GridExpInfo.Rows.length; i++) { 
      if (GridExpInfo.Rows[i].Cells[7].Value == "" || GridExpInfo.Rows[i].Cells[7].Value == "0") { 
       GridExpInfo.Rows[i].Cells[14].style.display = "none"; 
      } 
     } 
    }

, I는 시도 그 무엇에 대한 그래서하지만 여기 내 gridview 영문 혼합하지 마십시오

자바 스크립트와 C# 코드입니다. GridView1.Rows[i].Cells[14].style.display = "none"; 라인에 Visual Studio에서 TableCell does not contain a definition for 'style'...과 같은 오류가 표시되지 않습니까?

당신은 다음과 같이 사용한다 :

GridExpInfo.Rows[i].Cells[14].Visible = false;

그러나이 그리드에서 셀을 제거하고 해당 행의 열이 왼쪽으로 이동합니다. 그래서 사용자 Cell 14는 Cell 15의 내용을 포함하고 16 개 등의 15 개를 포함합니다.이 문제는 Cell 13에 colspan을 적용하여 수정할 수 있지만 Cell 13의 내용이 오버플로 할 수도 있음을 의미합니다.

행의 특정 값을 기준으로 버튼을 숨기는 것이 좋습니다.

<asp:Button Visible='<%# string.IsNullOrEmpty(Eval("value").ToString()) || Eval("value").ToString() != "0" %>' runat="server" Text="Generate invoice" ID="Button1" />

UPDATE는

그것은 영업 이익은 Obout에서 그리드를 사용 보인다. 이것은 아마도 "정상적인"그리드 기능이 다르게 작동한다는 것을 의미합니다.

<input type="button" value="Cancel" onclick="GridExpInfo.cancel()" class="button" style="display:<%# (Container.Value != "0" ? "block" : "none") %>" />

ListView 버튼을 사용하지 못하도록하는 해결책을 제공했습니다.

을 Default.aspx :

이

      <br /> 
     </ItemTemplate> 
</asp:ListView>

     Users.Add(new User() { ID = 2, name = "AT-2014", Status = "0" }); 

     return Users; 
    }

      Label status = (Label)ListView1.Items[i].FindControl("label3"); 
      Button button1 = (Button)ListView1.Items[i].FindControl("button1"); 

      if (status.Text == "1")
