hi all
how to set div opacity in asp.net using code behind c#
thanks

推荐答案

<div runat="server" id="divi">
</div>

并在后面的代码中:

and in code behind:

divi.Attributes.CssStyle.Add("opacity","0.5");

在ASP.Net中使用asp:Panel呈现div.因此，请在样式文件或页面中定义一个css类，并从代码后边设置CssClass 属性(或在.aspx页面本身中进行设置.)

例如，在aspx中:

In ASP.Net using asp:Panel renders a div. So define a css class in a style file or in the page and from code-behind set the CssClass property (or set in the .aspx page itself.

For example, in the aspx:

<asp:panel id="panel" runat="server" xmlns:asp="#unknown">

</asp:panel>

然后在后面的代码中:

Then in the code-behind:

protected void Page_Load(object sender, EventArgs e)
{
    panel.CssClass = "some-class";
}

或

or

<asp:panel id="panel" runat="server" cssclass="some-class" xmlns:asp="#unknown">

</asp:panel>

(或)

(or)

<div id="div1" runat="server">
</div>

protected void Page_Load(object sender, EventArgs e)
{
   div1.Attributes.Add("class","some-class");
}

附带说明，您还可以使用样式"客户端属性.

希望这会有所帮助！

As a side note, you could also use the "style" client-side property.

Hope this helps!
