关于关于一个删除按钮的问题

Question

 protected void Button1_Click(object sender, EventArgs e)

    {

        for (int i = 0; i <= GridView1.Rows.Count - 1; i++)

        {

            CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");

            if (cbox.Checked == true)

            {

               

                string sqlStr = "delete from Inventory where Code='" + Convert.ToUInt32(GridView1.DataKeys[i].Value) + "'";

                GetCon.ExecuteSql(sqlStr);

               

            }

            else

            {

                Response.Write(string.Format(GetRedirect.WINALERT,"你没有选择要删除的记录!"));

                Response.Write(string.Format(GetRedirect.REDIRECT,"InventoryManager.aspx"));

            }

        }

        bindToGridView();

    }

这是一个删除按钮触发的事件，可当我选中了一个checkbox后，它还是显示"你没有选择要删除的记录!"，是不是上面的判断逻辑有问题还是其他的错误，请执教。

protected void Button1_Click(object sender, EventArgs e)
{
    bool fHasDeleted = false;

    for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
    {
        CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
        if (cbox.Checked == true)
        {

            string sqlStr = "delete from Inventory where Code='" + Convert.ToUInt32(GridView1.DataKeys[i].Value) + "'";
            GetCon.ExecuteSql(sqlStr);
            fHasDeleted = true;
        }
    }

    if (!fHasDeleted)
    {
        Response.Write(string.Format(GetRedirect.WINALERT, "你没有选择要删除的记录!"));
        Response.Write(string.Format(GetRedirect.REDIRECT, "InventoryManager.aspx"));
    }
    bindToGridView();
}

protected void Button1_Click(object sender, EventArgs e)
{
    bool result = false;

    foreach (GridViewRow gvr in GridView1.Rows)
    {
        CheckBox cb1 = (CheckBox)gvr.FindControl("CheckBox1");
        if (cb1.Checked)
        {
            string clientId = gvr.Cells[0].Text;
            string operators = DropDownList1.SelectedValue;

            result = ClientAccess.SetOperator(clientId, operators);
        }
    }

    if (result)
    {
        Response.Write("<script>alert('添加成功！');</script>");
        PopulateControls();
    }
    else
    {
        Response.Write("<script>alert('添加失败！');</script>");
    }
}
