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>

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; 
}
