중계기에 :

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

당신은 그런 식으로 뭔가를 시도 할 수 있습니다 :

<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>
