GridView的主从多级嵌套

=========================================
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[
1
].FindControl(
“
GridView2
“
);
}
}
可是在FindControl(“GridView2”)后只有一个DataBind()方法，并没有DataSource这个属性，要怎样才能给里面的那个GridView2指定一个新的数据源呢？
——————————————————–
GridView GRTemp=(GridView)e.Row.Cells[1].FindControl(“GridView2”);
GRTemp.DataSource=你的source；
GRTemp.DataBind();
========================================================================================
Repeater嵌套:
=======================================================================================
在绑定分类品名时,绑定分类下的产品
private
void
rptCategories_ItemDataBound(
object
sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
BLL.Products products
=
new
BLL.Products();
if
(e.Item.ItemType
==
ListItemType.Item
||
e.Item.ItemType
==
ListItemType.AlternatingItem)
{
Repeater rptProduct
=
(Repeater) e.Item.FindControl(
“
rptProduct
“
);
//
找到分类Repeater关联的数据项
DataRowView rowv
=
(DataRowView)e.Item.DataItem;
//
提取分类ID
int
CategorieId
=
Convert.ToInt32(rowv[
“
ID
“
]);
//
根据分类ID查询该分类下的产品，并绑定产品Repeater
rptProduct.DataSource
=
products.GetProductsByCategorieId(CategorieId);
rptProduct.DataBind();
}
}
=========================================================================================
gridView嵌套:
========================================================================================
protected
void
gvUserList_RowDataBound(
object
sender, GridViewRowEventArgs e)
{
if
(e.Row.RowType
==
DataControlRowType.DataRow)
{
DataRowView rowv
=
(DataRowView)e.Row.DataItem;
Label lblCareer
=
(Label)e.Row.FindControl(
“
lblCareer
“
);
string
tmp_myCareer
=
rowv[
“
mycareer
“
].ToString().Trim();
}
}
