What are Hidden Fields in ASP.Net?

[beingchinmay]

• These are html input control with hidden type that store hidden data in the html

• The data stored in hidden field is available when form processed on the server or using JavaScript.

• Syntax - <input type="hidden" name="EVENTTARGET" id="EVENTTARGETID" value="" />

• Can store only one value in their value property. The value is saved as a string so we need to Typecast.

• There are two types of server control hidden fields -

 System.Web.UI.WebControls.HiddenField

 System.Web.UI.HtmlControls.HtmlInputHidden.

The HiddenField control is used to store a value that needs to be persisted across posts to the server. It is rendered as an <input type= "hidden"/> element. Normally view state, session state, and cookies are used to maintain the state of a Web Forms page.
