如何从后面的代码中禁用引导程序控件

Question

我有一个aspx页面：

<div class="form-vertical">
    <div class="form-group">

        <div class="row">
            <div class="col-sm-3">
                <asp:DropDownList runat="server" ClientIDMode="Static" ID="ddlLocation" CssClass="form-control required" AppendDataBoundItems="true" DataTextField="location_name" DataValueField="location_id" OnInit="ddllocation_Init">
                    <asp:ListItem Value="" Text="Select location..">
                    </asp:ListItem>
                </asp:DropDownList>
            </div>
        </div>
        <br />

        <div class="row">
            <div class="col-sm-4">
                <button type="button" id="btnAdd" class="btn btn-success pull-center"><i class="fa fa-search"></i>Add</button>
            </div>
        </div>

    </div>

</div>

....
Some more content here that needs to be displayed.

基于某些条件，当asp.net页面加载时，我想选择隐藏整个div class =“ form-vertical”要么禁用所有控件

可以禁用asp.net控件，但如何禁用按钮-btnAdd

有什么建议吗？
