at 1st you need to set CommandArgument=row index, then use this code in onrowcommand event.

.aspx code:

ASP.NET

<asp:GridView ID="dtgView" runat="server" AutoGenerateColumns="False" CellPadding="4"
                                                    ForeColor="#333333" GridLines="None" ShowFooter="true" OnRowCommand="dtgView_RowCommand">
                                                    <RowStyle BackColor="#EFF3FB" />
                                                    <Columns>
                                                        <asp:TemplateField>
                                                            <ItemTemplate>
                                                                <asp:ImageButton ID="btnSelect" runat="server" CommandName="RSelect" CommandArgument='<%#Eval("RIndex") %>'
                                                                    ImageUrl="~/Icon/page_edit.gif" />
                                                            </ItemTemplate>
                                                        </asp:TemplateField>
                                                        <asp:TemplateField>
                                                            <ItemTemplate>
                                                                <asp:DropDownList ID="ddl" runat="server">
                                                                </asp:DropDownList>
                                                            </ItemTemplate>
                                                        </asp:TemplateField>
                                                    </Columns>
                                                    <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
                                                    <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
                                                    <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
                                                    <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
                                                    <EditRowStyle BackColor="#2461BF" />
                                                    <AlternatingRowStyle BackColor="White" />
                                                </asp:GridView>

.cs code:

C#

class dtgData
        {
            int _RIndex;
            public int RIndex
            {
                get { return _RIndex; }
                set { _RIndex = value; }
            }
        }

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                List<dtgData> list = new List<dtgData>();
                dtgData ob = new dtgData();
                for (int i = 0; i <= 4; i++)
                {
                    ob = new dtgData();
                    ob.RIndex = i;
                    list.Add(ob);
                }
                dtgView.DataSource = list;
                dtgView.DataBind();
            }
        }

protected void dtgView_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            //Need to set CommandArgument=row index
            int rowCount = 0;
            foreach (GridViewRow row in dtgView.Rows)
            {
                if (rowCount == Convert.ToInt16(e.CommandArgument))
                {
                    string str = ((DropDownList)row.FindControl("ddl")).SelectedValue.ToString();
                }
                rowCount++;
            }
        }

here,
dtgView=GridView
ddl=DropDownList inside your gridview

try this...
