=========================================

我已经通过FindControl找到这个gridview，可是现在的问题是我要给这个gridview里帮定的数据源是个新的，和外面的gridview数据源不是同一个！下面是我的部分代码： 

<
asp:GridView ID
=
“
GridView1
“
 runat
=
“
server
“
 AutoGenerateColumns
=
“
False
“
 OnRowDataBound
=
“
GridView1_RowDataBound
“
>
 
   
<
Columns
>
 
     
<
asp:BoundField DataField
=
“
type
“
 HeaderText
=
“
type
“
 
/>
 
       
<
asp:TemplateField
>
 
         
<
ItemTemplate
>
 
           
<
asp:GridView ID
=
“
GridView2
“
 runat
=
“
server
“
 AutoGenerateColumns
=
“
False
“
 EnableViewState
=
“
False
“
>
 
             
<
Columns
>
 
                
<
asp:BoundField DataField
=
“
pub_id
“
 HeaderText
=
“
pub_id
“
 
/>
 
             
</
Columns
>
 
           
</
asp:GridView
>
 
         
</
ItemTemplate
>
 
       
</
asp:TemplateField
>
 
    
</
Columns
>
 

</
asp:GridView

protected
 
void
 GridView1_RowDataBound(
object
 sender, GridViewRowEventArgs e) 
     { 
         
if
 (e.Row.RowType 
==
 DataControlRowType.DataRow) 
         { 
             e.Row.Cells[

].FindControl(
“

); 
         } 
     }
