you can use contains instead of == 

<asp:checkbox id="chkview" checked='<%#bool.parse(eval("permissions").tostring().contains("view") ? "true": "false") %>' runat="server" />view             <asp:checkbox id="chkinsert" checked='<%#bool.parse (eval("permissions").tostring().contains("insert") ? "true": "false") %>' runat="server" />insert             <asp:checkbox id="chkupdate" checked='<%#bool.parse (eval("permissions").tostring().contains("update") ? "true": "false") %>' runat="server" />update             <asp:checkbox id="chkdelete" checked='<%#bool.parse (eval("permissions").tostring().contains("delete") ? "true": "false") %>' runat="server" />delete
