Conditionally Redirect to other page on click of Button inside GridView

I have created the dummy table which contains the data as you have mention. On Button Click event i am checking the value of Type in Gridview. If its External then i am redirecting it to the website which is mention in the Address column of the GridView

HTML:

<form id="form1" runat="server">
    <div>
        <asp:GridView ID="gvLinks" runat="server" AutoGenerateColumns="false">
            <Columns>
                <asp:BoundField DataField="ID" HeaderText="ID" />
                <asp:BoundField DataField="Address" HeaderText="Address" />
                <asp:BoundField DataField="Type" HeaderText="Type" />
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="btnLink" runat="server" Text="View" OnClick="OpenExternalLink" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
    </div>
    </form>

C#:

protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {
                this.PopulateGrid();
            }
        }

        private void PopulateGrid()
        {
            DataTable dt2 = new DataTable();
            dt2.Columns.AddRange(new DataColumn[3]{new DataColumn("ID",typeof(int)),
                                new DataColumn("Address",typeof(string)),
                                new DataColumn("Type",typeof(string))
                               });
            dt2.Rows.Add(1, "Abc", "Fixed");
            dt2.Rows.Add(2, "http://www.google.com", "External");
            dt2.Rows.Add(3, "Xyz", "Fixed");
            dt2.Rows.Add(4, "Pqo", "Fixed");
            dt2.Rows.Add(5, "http://www.w3schools.com", "External");
            dt2.Rows.Add(6, "http://www.aspforums.com", "External");
            dt2.Rows.Add(7, "Abc", "Fixed");
            dt2.Rows.Add(8, "Abc", "Fixed");
            dt2.Rows.Add(9, "http://www.aspsnippets.com", "External");
            dt2.Rows.Add(10, "Abc", "Fixed");
            this.gvLinks.DataSource = dt2;
            this.gvLinks.DataBind();

        }

        protected void OpenExternalLink(object sender, EventArgs e)
        {
            GridViewRow row = ((sender as Button).NamingContainer as GridViewRow);
            if (row.Cells[2].Text == "External")
            {
                Response.Redirect(row.Cells[1].Text);
            }
        }
