First give an id to your div like this 首先像这样给你的div一个ID
<div runat="server" id="div1"></div>
And then in your C# code write this to add style to div. 然后在您的C#代码中编写此代码以向div添加样式。
string style = div1.Style[HtmlTextWriterStyle.Display];
if(style.ToLower()=="none")
div1.Style.Add(HtmlTextWriterStyle.Display, "block");
And here is how you can remove style. 这是删除样式的方法。
div1.Style.Remove(HtmlTextWriterStyle.Display);
<% var display = "block";
if(isHidden){
display = "none";
}
%>
<div runat="server" class="labels" style="display:<%=display%>; height: 100%; font-family: 'Segoe UI';">
<asp:Label ID="Label4" runat="server" Text="Description:" Font-Bold="True"></asp:Label>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<br />
<asp:Label ID="Label5" runat="server" Text="Impact:" Font-Bold="True"></asp:Label>
<asp:Label ID="Label2" runat="server" Text="Label"></asp:Label>
