Question

So it looks like if I add style such as background color to LinkButton in my .cs code, it overrides any css I have that applies to it.

is there any way to add style rather than replace it in my code behind? Thanks!
I am using link button as a menu, so active linkButton should have different background color.
so my solution was when the user clicks on the link button in my event handler I do something like:

   lnkView.BackColor = System.Drawing.Color.FromName("#369");

But then my hover style which I have in my css will no longer work:

.navlist a:hover
{
    color: #fff;
    background-color: #369;
    text-decoration: none;
}

in my aspx:

<ul class="navlist">
        <li><asp:LinkButton ID="lnkView" runat="server">view</asp:LinkButton></li>
        <li><asp:LinkButton ID="lnkCreateNew" runat="server">create new</asp:LinkButton></li>
    </ul>

EDIT: Your question is unclear, but you appear to be mis-understanding CSS. Adding background-color to the style property will not cause it to completely ignore any CSS rules. Rather, it will override any CSS rules for the background-color property, but will not affect any other rules.

If you don’t want to override the background-color property from the CSS rule, add the !important flag to the CSS rule in :hover, like this:

background-color: #369 !important;

Also, change the color so that the change wil be noticable.

Alternatively, you could add a new CSS rule for .navlist a:link .Active with your background color, then add the Active class in code. (lnkView.CssClass += "Active")

By the way, instead of calling Color.FromName, you should write Color.FromArgb(0x33, 0x66, 0x99).
