datagrid和repeader控件中替换标识值的方法

<asp:datagrid id="dglist" runat="server" width="100%" autogeneratecolumns="false"> 
<columns> 
<asp:boundcolumn datafield="cop_g_no" headertext="物料号/成品货号"></asp:boundcolumn> 
<asp:boundcolumn datafield="qty" headertext="数量"></asp:boundcolumn> 
<asp:templatecolumn headertext="物料标识"> 
<itemtemplate> 
<%#gettranstype(databinder.eval(container.dataitem, "flag"))%> 
</itemtemplate> 
</asp:templatecolumn> 
</columns> 
</asp:datagrid>
直接调用后台方法：
<asp:templatecolumn headertext="原产地"> 
<itemtemplate> 
<%# (common.constant.countrylist.containskey(eval("country") + "")) ? common.constant.countrylist[eval("country") + ""] : eval("country") + "" %> 
</itemtemplate> 
</asp:templatecolumn>

public string gettranstype(object obj) 
{ 
string type_flag = convert.tostring(obj); 
string strreturn = ""; 
switch (type_flag) 
{ 
case "1": strreturn = "在厂产品"; break; 
case "2": strreturn = "在厂半成品"; break; 
case "3": strreturn = "已出库未报关成品"; break; 
case "i": strreturn = "在厂原材料数量"; break; 
case "y": strreturn = "已报关未入库料件数量"; break; 
case "w": strreturn = "已入库未报关料件数量"; break; 
default: ; break; 
} 
return strreturn; 
}
