Question

I am using asp.NET 4.0 with C# and have recently created a custom design for my local web application. I would like that when a page is selected, it has a different background colour (usually in plain html + css we just set a menu item as active). I tried using but it is not working, it stays the same colour as the others. Does any one has any experience with this?

Code in Site Master:

            <h2>Dashboard</h2>
            <asp:Menu ID="NavigationMenu" runat="server" CssClass="menu" EnableViewState="false" IncludeStyleBlock="false" Orientation="Vertical" >
                <StaticSelectedStyle CssClass="selectedMenu" /> 
                <Items>
                    <asp:MenuItem NavigateUrl="~/Default.aspx" Text="View Submissions"/>
                    <asp:MenuItem NavigateUrl="~/Imports.aspx" Text="Import"/>
                    <asp:MenuItem NavigateUrl="~/Submission.aspx" Text="Insert Submission"/>
                    <asp:MenuItem NavigateUrl="~/Reports.aspx" Text="Reports"/>
                    <asp:MenuItem NavigateUrl="~/CurrencyMaintenance.aspx" Text="Currency Maintenance" />
                    <asp:MenuItem NavigateUrl="~/Remittance.aspx" Text="Remittance" />
                </Items>
            </asp:Menu>

CSS:

/* TAB MENU   
----------------------------------------------------------*/
div.hideSkiplink
{
    background-color:#3a4f63;
    width:100%;
}

div.menu
{
    padding: 4px 0px 4px 8px;
}

div.menu ul
{
    list-style: none;
    margin: 0px;
    padding: 0px;
    width: auto;
}

div.menu ul li a, div.menu ul li a:visited
{
    background-color: #FFF; /*680840*/
    border: 1px #4e667d solid;
    height: 20px;
    width: 175px;
    color: #000; /*FFF*/
    display: block;
    line-height: 1.35em;
    padding: 4px 20px;
    text-decoration: none;
    white-space: nowrap;
}

div.menu ul li a:hover
{
    background-color: #680840;
    color: #FFF;
    text-decoration: none;
}

.selectedMenu
{
    background-color: #680840 !important;
    color: #FFF !important;
    text-decoration: none !important;
}

div.menu ul li a:active
{
    background-color: #680840;
    color: #cfdbe6;
    text-decoration: none;
}

This is what it looks like on Hover, I would like a similar effect on selected.

This seems to be a bug with the .NET menu. There is some information regarding this here. What you might want to do then is remove the staticSelectedStyle attribute and simply add this to your css:

.menu a.static.selected
{
    background-color: #680840 !important;
    color: #FFF !important;
    text-decoration: none !important;
}

You might also have to add some code to your master’s page load to determine which should be the selected item like this:

protected void Page_Load(object sender, EventArgs e)
{
    string path = Request.AppRelativeCurrentExecutionFilePath;
    foreach (MenuItem item in NavigationMenu.Items)
    {
        item.Selected = item.NavigateUrl.Equals(path, StringComparison.InvariantCultureIgnoreCase);
    }
}
