ASP.NET in a Nutshell

Name

HtmlControl

Synopsis

This is the base class for all HTML server controls. It includes basic functionality—like the Disabled property, which you can use to make a control read-only, and the TagName property, which identifies the HTML tag that underlies this control (for example, “div” or “a”).

Additionally, you can set and retrieve various other properties through the weakly typed Attributes collection, which contains a name/value collection of all the attributes applied to a tag. You can add a new attribute by assigning to it, as in MyText.Attributes("onblur")="javascript:alert('Focus lost!');". This statement, which adds a client-side JavaScript event through an attribute, is the equivalent of using the tag <input type="text" id="MyText" onblur="javascript:alert('Focus lost!');" runat="server"/>. Some attributes may be provided as properties in the derived class. Another dictionary collection, Style, allows you to specify CSS properties for a tag (as in MyText.Style("width") = "120px").
