如何添加动作按钮，如编辑和删除到动态网格视图

我添加了一个动态生成的GridView。我从DB取行，并将其加载到数据表。我想添加编辑和删除按钮到这个数据表，并将其绑定到GridView，这样我就可以编辑和删除GridView的内容。GridView生成了不止一次，并且在循环中调用，因为它需要生成周的时间表。下面是绑定数据和生成GridView的源代码:

protected void BindData(string str)
{
    string[] startdate = getdate(str);
    int firstdate = Convert.ToInt32(startdate[1]);
    int lastdate = firstdate + 7;
    string enddate = startdate[0]+"/"+Convert.ToString(lastdate)+"/"+startdate[2];
    if (conn.State == ConnectionState.Closed)
        conn.Open();
    SqlCommand cmd = new SqlCommand("SELECT DISTINCT CONVERT (varchar(25), Cale_WeekDate,106) AS 'Date',Cale_DayName AS 'Day',Cale_Task8 AS '08:00 AM',Cale_Task9 AS '09:00 AM',Cale_Task10 AS '10:00 AM',Cale_Task11 AS '11:00 AM',Cale_Task12 AS '12:00 PM',Cale_Task13 AS '1:00 PM' FROM Calendar WHERE Cale_WeekDate BETWEEN '"+str+"' AND '"+enddate+"'", conn);
    DataSet ds = new DataSet();
    DataTable dt = new DataTable();
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    da.Fill(ds);               
    GridView gvTimeSheet = new GridView();
    //gvTimeSheet.ID = "gvTimeSheet" + gridcount;
    gvTimeSheet.AutoGenerateColumns = false;
    dt = ds.Tables[0];
    for (int i = 0; i < dt.Columns.Count; i++)
    {
        BoundField boundfield = new BoundField();
        boundfield.DataField = dt.Columns[i].ColumnName.ToString();
        boundfield.HeaderText = dt.Columns[i].ColumnName.ToString();
        gvTimeSheet.Columns.Add(boundfield);
    }
    gvTimeSheet.DataSource = dt;
    gvTimeSheet.DataBind();
    gvTimeSheet.Width = 600;
    gvTimeSheet.HeaderStyle.CssClass = "header";
    gvTimeSheet.RowStyle.CssClass = "rowstyle";
    Panel1.Controls.Add(gvTimeSheet);
    HtmlGenericControl linebreak = new HtmlGenericControl("br");            
    Panel1.Controls.Add(linebreak);       
}

    <asp:GridView>
        <Columns>
            <asp:TemplateField HeaderText="Test">
                <ItemTemplate>
                    <asp:Button ID="btnTest" CommandArgument='btnTest' runat="server" Text="Test et" OnClick="btnTest_Click" />
                    <asp:Button ID="btnVerify" CommandArgument='btnVerify' runat="server" Text="Verify" OnClick="btnVerify_Click" />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

protected void btnTest_Click(object sender, EventArgs e)
{
}
protected void btnVerify_Click(object sender, EventArgs e)
{
}
