GridView 每行邦定 Dropdownlist 控件，然后点页面的“确定”按钮，如何把每行的dropdownlist中的值保存下来？

页面：
<asp:GridView ID="DtgView" runat="server" AutoGenerateColumns="False" Width="98%" Height=98%
BorderStyle="None" GridLines="Horizontal" frame="void" AllowPaging="True" EnableViewState="false"
OnRowDataBound="DtgView_RowDataBound">
<Columns>

<asp:BoundField DataField="EquiId" HeaderText="EquiId" Visible=false />


<asp:TemplateField HeaderText="设备名称">
<ItemTemplate>
<%#GetEquipName(DataBinder.Eval(Container.DataItem, "EquiId").ToString())%>
</ItemTemplate>
<ItemStyle Width="30%" />
</asp:TemplateField >



<asp:TemplateField HeaderText="确认状态">
<ItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server"></asp:DropDownList>
</ItemTemplate>
<ItemStyle Width="10%" />
</asp:TemplateField >

<tr>
<td align=center>
<asp:Button runat="server" ID="btn_save" Text="保　存" CssClass="NewButton" CausesValidation="false" OnClick="btn_save_Click" />
       
<asp:Button runat="server" ID="btn_submit" Text="确　定" CssClass="NewButton" CausesValidation="false" OnClick="btn_submit_Click" />
</td>
</tr>

服务器：
protected void DtgView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList ddl = (DropDownList)e.Row.FindControl("DropDownList1");
ddl.DataSource = task.GetConfirmStatus();
ddl.DataTextField = "StatusName";
ddl.DataValueField = "id";
ddl.DataBind();
ListItem li = new ListItem("请选择", "0");
ddl.Items.Insert(0, li);
}
}

protected void btn_save_Click(object sender, EventArgs e)
{
//这块怎么写？？？？急！
}

我需要点击“确定键”，将所有的dropdownlist里的值和对应的行的equiid保存到数据库中。不知道该用gridview中的哪个事件能做到，谁能教教我？多谢！

<asp:DropDownList ID="ddlProductType" runat="server">
</asp:DropDownList>
<asp:HiddenField ID="HidTypeID" Value='<%# Eval("主键Id") %>' runat="server" />
后台循环遍历每一行 得到数据

[harderLi]

i=0;i<Gridview1.Rows.count;i++
GridView1.rows[i].cells[2]

我先试一试。多谢ls两位。关键是后台遍历是用gridview的事件还是自己写循环？

不行啊，得到的是这些：
System.Web.UI.WebControls.DataControlFieldCell; System.Web.UI.WebControls.DataControlFieldCell; System.Web.UI.WebControls.DataControlFieldCell; System.Web.UI.WebControls.DataControlFieldCell; System.Web.UI.WebControls.DataControlFieldCell; System.Web.UI.WebControls.DataControlFieldCell; System.Web.UI.WebControls.DataControlFieldCell; System.Web.UI.WebControls.DataControlFieldCell; System.Web.UI.WebControls.DataControlFieldCell; System.Web.UI.WebControls.DataControlFieldCell

可以了！
这么写就可以了：
protected void btn_save_Click(object sender, EventArgs e)
{
string var = "";
for (int i = 0; i < DtgView.Rows.Count; i++)
{
var = var + "; " + ((DropDownList)DtgView.Rows[i].Cells[2].FindControl("DropDownList1")).SelectedValue;
}
Response.Write(var);
}

结果为：; 1; 2; 0; 0; 0; 0; 0; 0; 0; 0

多谢！
