in newest framework they can be done like this:

MyDivId.CssClass.Replace("addedClass", "");

but in .net 2.0 not found CssClass

some proposals? thx in advance!

Answer 1

You can make the same. CssClass just return string, so you can do like this

MyDivId.Attributes["class"] = MyDivId.Attributes["class"].Replace("addedClass", "");

UPDATE1

Or just more easy to use way to create extension class that will do the same:

public static class ControlExtension
{
    public static void RemoveCssClass(this HtmlControl control, string cssClassName)
    {
        var val = control.Attributes["class"];
        val = val.Replace(cssClassName, string.Empty);
        control.Attributes["class"] = val;
    }
}

And then use it:

MyDivId.RemoveCssClass("addedClass");
