我的za.aspx页面中有一个服务器端div标签,其中包含标签和下拉列表

<div id="SkillsStatus" runat="server" style="display:none">
    <asp:Label ID="Label1" runat="server" Text="Please select a skill" 
        Font-Bold="True" Font-Italic="False" Font-Size="Larger"></asp:Label>
    <asp:DropDownList ID="SkillsStatusddl" runat="server" AutoPostBack="True"
        onselectedindexchanged="SkillsStatusddl_SelectedIndexChanged" 
        CssClass="selectpicker">
        <asp:ListItem Value="0">Choose An Option</asp:ListItem>

    </asp:DropDownList>

现在,我将数据绑定到codebehind文件的dropdownlist,我在文件后面的代码中绑定了一个cusom控件

 PreChatSurvey customPrechatSurvey = new PreChatSurvey
    {
        ID = "customPrechatSurvey",
        ForeColor = Color.Black,
        SurveyId = 0,
        IsPreview = false
    }; 

     protected override void OnInit(EventArgs e)
    {


        SkillsStatus.Attributes.Add("style", "display:block");
            SkillsStatusddl.DataSource = "";
            orgID = Convert.ToInt32(Request.QueryString["OrgID"]);

            DataSet ds = SubCampaignBase.GetSkillStatus(orgID);
            DataTable dt = ds.Tables[0];
            foreach (DataRow row in dt.Rows)
            {
                ListItem li = new ListItem();
                li.Text = row["SubCampaignName"].ToString();
                li.Value = row["SubCampaignId"].ToString();
                li.Attributes.Add("data-icon", "glyphicon glyphicon-user");

                if (Convert.ToBoolean(row["soa_status"]))
                {
                    li.Attributes.CssStyle.Add(HtmlTextWriterStyle.Color, "green");
                    li.Attributes.CssStyle.Add(HtmlTextWriterStyle.BackgroundColor, "white");
                }
                else
                {
                    li.Attributes.CssStyle.Add(HtmlTextWriterStyle.Color, "black");
                    li.Attributes.CssStyle.Add(HtmlTextWriterStyle.BackgroundColor, "white");

                }

                SkillsStatusddl.Items.Add(li);

            }
         base.OnInit(e);

        }

现在它在同一页面上加载自定义控件和下拉列表,这个自定义控件有一个按钮,点击该按钮,我想隐藏包含下拉列表的div标签,所以我按下按钮点击

private void btnSubmit_Click(object sender, EventArgs e)
    {

            DropDownList dd = (DropDownList)this.Parent.FindControl("SkillsStatusddl");
            dd.Enabled = false;
            HtmlGenericControl div = (HtmlGenericControl)this.Parent.FindControl("SkillsStatus");
            div.Attributes.Add("style", "display:none");
    }

为了安全起见,我尝试了两件事, 但没有任何工作,div既不会消失也不会下拉被禁用
