如何从 ASP.Net Webforms 代码隐藏中设置 Summernote 文本

问：

我已将 Summernote 包含在 ASP.NET Webforms 页面中，但是当我尝试从代码隐藏中为其设置文本时，会出现 html 文本，但工具栏消失了。

这是 Summernote 在设置文本之前的样子......默认 Summernote 外观

这是尝试设置文本时的样子......设置文本

这是我对 Summernote 和 Bootstrap 的包含......

我的 Summernote html 和 javascript 是......

<p>
    <asp:Label ID="lblBody" runat="server" Text="Body" class="myLargeFont"></asp:Label>
    <textarea ClientIdMode="Static" id="summernote" name="summernote" runat="server" style="width:650px; height:550px;"></textarea>
    <asp:ListBox ID="lstAttachments" runat="server" Visible="false" Height="200px" Width="150px"></asp:ListBox>
    <asp:Button ID="btnShowAttachment" runat="server" Text="Load" Visible="false" />
</p>

<script>
    $(document).ready(function () {
        $('#summernote').summernote({
            placeholder: 'Hello Bootstrap 4',
            //tabsize: 2,
            height: 300,
            toolbar: [
                // [groupName, [list of button]]
                ['fontname', ['fontname']],
                ['fontsize', ['fontsize']],
                ['style', ['bold', 'italic', 'underline', 'clear']],
                ['font', ['strikethrough', 'superscript', 'subscript']],
                ['color', ['color']],
                ['para', ['ul', 'ol', 'paragraph']],
                ['height', ['height']],
                ['table', ['table']],
                ['insert', ['link', 'picture', 'video']],
                ['view', ['codeview']]
            ]
        });
    });
</script>

用于设置文本的按钮的代码是...

<p>
    <asp:Button ID="btnAddEmail" runat="server" Text="Add email" class="myLargeFont" OnClick="btnAddEmail_Click" />
</p>

private static string summernoteTextTest()
{
    string testText = "<p>This is some text for testing in summernote.</p><p>How does it look?</p>";
    return testText;
}

protected void btnAddEmail_Click(object sender, EventArgs e)
{
    string testtext = summernoteTextTest();
    summernote.InnerText = testtext;
}
