Difference between HTML ReadOnly and Enabled
|
The TextBox with the ReadOnly attribute will be displayed as the following markup on the client: <input readonly = "readonly"> The TextBox with the Enabled attribute will be displayed as the following markup on the client: ＜input disabled="disabled"＞ Html server controls use a class derived from the HtmlControl base class (full class name System.Web.UI.HtmlControls), which only has the Disabled property. According to W3C specifications: http://www.w3.org/TR/REC-html40/interact/forms.html#h-17.12 Inputs set to disabled will have the following restrictions: <1> Can accept focus <2> Will be skipped when using the tab key <3> May not be successful Inputs set to readonly will have the following restrictions: <1> Can accept focus but cannot be modified <2> Use the tab key to navigate <3> May be successful Only successful form elements have valid data, which means they can be submitted. Disabled and readonly text input boxes can only be modified by scripts |
