FindControl<\/code> is only able to find server-side controls, not plain HTML tags. In your case it means that you should add attribute runat=\"server\"<\/code> to the ClientTab<\/code> div:<\/p>\n

<li>\n    <a href=\"https:\/\/stackoverflow.com\/questions\/17292020\/Clients.aspx\">\n        <div id=\"ClientTab\" class=\"MainNavigationContainerItem\" runat=\"server\"> Client<\/div>\n    <\/a>\n<\/li>\n<\/code><\/pre>\n
However your code seems to add yet another class<\/code> tag to this control, which might not be what you are looking for. Most likely what you want to have is<\/p>\n
class=\"MainNavigationContainerItem ClientTabActive\"\n<\/code><\/pre>\n
in which case the second line of your code-behind should look like this:<\/p>\n
currdiv.Attributes[\"class\"] = string.Format(\"{0} {1}\", currdiv.Attributes[\"class\"], \"ClientTabActive\";\n<\/code><\/pre>\n<\/p><\/div>\n
