Default Gridview and DropDownList

Hi,

I have a gridview with a templete field. In the template field is a DropDownList.

Code:
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
            AllowSorting="True" AutoGenerateColumns="False" DataSourceID="SqlDataSource1">
            <Columns>
                <asp:HyperLinkField DataNavigateUrlFields="RequestID" DataNavigateUrlFormatString="RequestDetails.aspx?RequestID={0}"
                    DataTextField="ReportTitle" HeaderText="Report Title" SortExpression="ReportTitle" >
                    <HeaderStyle ForeColor="White" />
                </asp:HyperLinkField>
                <asp:BoundField DataField="StatusName" HeaderText="Status" SortExpression="StatusName" >
                    <HeaderStyle ForeColor="White" />
                </asp:BoundField>
                <asp:BoundField DataField="RequestDate" HeaderText="RequestDate" SortExpression="RequestDate" >
                    <HeaderStyle ForeColor="White" />
                </asp:BoundField>
                <asp:TemplateField HeaderText="Request Options">
                    <HeaderStyle ForeColor="White" />
                    <ItemTemplate>
                        <asp:DropDownList ID="ddlRequestOptions" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ddlRequestOptions_SelectedIndexChanged">
                            <asp:ListItem Selected="True"></asp:ListItem>
                            <asp:ListItem Value="Chg">Change</asp:ListItem>
                            <asp:ListItem Value="Can">Cancel</asp:ListItem>
                            <asp:ListItem Value="Up">Update</asp:ListItem>
                        </asp:DropDownList>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
            <RowStyle BackColor="#E8E8E8" />
            <HeaderStyle BackColor="#36578C" />
        </asp:GridView>
In the selectedindexchanged event for the drop down list I would like to do something like this:
RequestChange.aspx?RequestID = 12345

The request id would come from the row they used the dropdownlist in.

Thanks
Extended

Here is the solution I came up with:
Code:
protected void ddlRequestOptions_SelectedIndexChanged(object sender, EventArgs e)
    {
        DropDownList ddl = (DropDownList)sender;
        GridViewRow row = (GridViewRow)ddl.NamingContainer;
        string requestid = ((Label)row.FindControl("lblRequestID")).Text;
        string type = ddl.SelectedValue;

Thank you - this is almost exactly what I needed. One slight mod for what I needed and that was the datakeyname for the row where the dropdownlist was. I got that with this code:

Code:
Protected Sub DdlFy_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)

Dim fyDropDown As DropDownList = sender
Dim row As GridViewRow = DirectCast(fyDropDown.NamingContainer, GridViewRow)
Dim projectId As Integer = GridView1.DataKeys(row.RowIndex).Item("ProjectId")

End Sub
