一个页面错误，我找了半天也不知是什么原因，请大虾指点
我的网面出现下面错误：
“System.Data.DataRowView”不包含名称为   WID   的属性。


我的网页代码部分如下：
SqlDataAdapter   da=new   SqlDataAdapter   ( "select   IID,IGname,IWNumber,IQuantity,IPrice,IProvider,IMangner,IHandler   from   [Irecords]   ",cn);
//创建并填充DataSet
DataSet   ds=new   DataSet   ();
da.Fill   (ds);
in_storemanage.DataSource   =ds;
in_storemanage.DataBind   ();
cn.Close   ();


控件代码：
<asp:datagrid   id= "in_storemanage "   runat= "server "   Width= "100% "   OnDeleteCommand= "DataGrid_Delete "
OnCancelCommand= "DataGrid_Cancel "   OnEditCommand= "DataGrid_Edit "   OnUpdateCommand= "DataGrid_Update "   DataKeyField= "WID "   AutoGenerateColumns= "False ">
<Columns>
<asp:BoundColumn   DataField= "IID "   ReadOnly= "True "   HeaderText= "编号 "> </asp:BoundColumn>
<asp:BoundColumn   DataField= "IGname "   HeaderText= "货品名称 "> </asp:BoundColumn>
<asp:BoundColumn   DataField= "IWNumber "   HeaderText= "仓库编号 "> </asp:BoundColumn>
<asp:BoundColumn   DataField= "IQuantity "   HeaderText= "数量 "> </asp:BoundColumn>
<asp:BoundColumn   DataField= "IPrice "   HeaderText= "单价 "> </asp:BoundColumn>
<asp:BoundColumn   DataField= "IProvider "   HeaderText= "货品提供商 "> </asp:BoundColumn>
<asp:BoundColumn   DataField= "IMangner "   HeaderText= "收货人 "> </asp:BoundColumn>
<asp:BoundColumn   DataField= "IHandler "   HeaderText= "备注 "> </asp:BoundColumn>
<asp:EditCommandColumn   ButtonType= "LinkButton "   UpdateText= "更新 "   CancelText= "取消 "   EditText= "编辑 "> </asp:EditCommandColumn>
<asp:ButtonColumn   Text= "删除 "   CommandName= "Delete "> </asp:ButtonColumn>
</Columns>
</asp:datagrid>

请问这是什么原因？


------解决方案--------------------
DataKeyField= "WID " 你定义了DataKey,但你的sql查询里并没有包括WID字段
------解决方案--------------------
DataKeyField= "WID "
确实是有问题哦
错误提示明显指出了 你的查询里没有加入WID这个值 但是你却定义了这个的DataKeyField
