How to add an attribute to a html control in code behind?

[Imran Aziz]

Hello All,

I have a navigation system for the site , in which the links are highlighted
based on which section the site is in. Now the issue is that I do that using
a class="thissection" attribute as show in the below example

THEMES</a></li>

How can I dynamically alter it in code behind, that is add attributes to an
html control using code behind ?

My current code behind does something like this to make the links bold, but
need to add the class attribute to the currently selected section.



Uri inUrl = Request.Url;

String strURL = inUrl.AbsoluteUri;

if (strURL.IndexOf("themes") > 0)

{

n_themes.InnerHtml = "<strong>THEMES</strong>";

n_themes = "";

}

else

{

if (strURL.IndexOf("bookmarks") > 0)

{

n_bookmarks.InnerHtml = "<strong>BOOKMARKS</strong>";

}

else

{

if (strURL.IndexOf("members") > 0)

{

n_members.InnerHtml = "<strong>MEMBERS</strong>";

}

else

{

if (strURL.IndexOf("sources") > 0)

{

n_sources.InnerHtml = "<strong>SOURCES</strong>";

}

else

{

if (strURL.IndexOf("_admin") > 0)

{

n_admin.InnerHtml = "<strong>ADMIN</strong>";

}

else

{

n_home.InnerHtml = "<strong>HOME</strong>";

}

}

}

}

}



Thanks a lot,



Imran

If you add the runat="server" attribute to the element you can call the
element on the code behind by its id as an HtmlGenericControl and then set
the attributes like

this.id.Attributes["Attribute"] = value
