檢查值槽IF直放站

Question

<asp:Repeater ID="rptEntries" runat="server" DataSourceID="dsEntries"> 
    <ItemTemplate> 
     <% 
     if (Convert.ToInt16(Eval("entryWinner")) == 1) 
     { 
     %> 
      <%# "<div class=\"imgThumb draggable\" style=\"background-image:url('uploads/" 
       + Eval("entryImagename") + "');\" data-id=\"" + Eval("pk_entryId") 
       + "\"></div>" 
      %> 
     <% 
      }else{ 
     %> 
      <%# "<div class=\"imgThumb draggable\" style=\"background-image:url('uploads/" 
       + Eval("entryImagename") + "'); filter: grayscale(100%);\" data-id=\"" 
       + Eval("pk_entryId") + "\"></div>" 
      %> 
     <% 
      } 
     %> 
    </ItemTemplate> 
</asp:Repeater> 

我想顯示之前檢查entryWinner TE的價值，但它給格蘭以下錯誤：

Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

您可以嘗試類似的東西：

<asp:Repeater ID="rptEntries" runat="server" DataSourceID="dsEntries"> 
    <ItemTemplate> 
      <%# String.Format("<div class=\"imgThumb draggable\" style=\"background-image:url('uploads/{0}');{1}\" data-id=\"{2}\"></div>" 
,Eval("entryImagename") 
,(Convert.ToInt16(Eval("entryWinner")) == 1)?"":" filter: grayscale(100%);",Eval("pk_entryId"))%> 
     </ItemTemplate> 

</asp:Repeater>
