Difference between AutoPostBack=True and AutoPostBack=False?

Question

What\'s the difference between AutoPostBack=True and AutoPostBack=False?

Answer 1

AutopostBack :

AutopostBack is a property of the controls which enables the post back on the changes of the web control.

Difference between AutopostBack=True and AutoPostBack=False:

If the AutopostBack property is set to true, a post back is sent immediately to the server

If the AutopostBack property is set to false, then no post back occurs.

Answer 2

AutoPostBack = true permits control to post back to the server. It is associated with an Event.

Example:

<asp:DropDownList id="id" runat="server" AutoPostBack="true" OnSelectIndexChanged="..."/>

The aspx page with the above drop down list does not need an asp:button to do the post back. When you change an option in the drop down list, the page gets posted back to the server.

Default value of AutoPostBack on control is false.

Answer 3

AutoPostBack property:

Asp.net controls which cannot submit the Form (PostBack) on their own and hence ASP.Net has provided a feature using

 AutoPostBack = "true"

: which controls like DropDownList, CheckBoxList, RadioButtonList, etc. can perform PostBack(when clicked on it).

And

AutoPostBack = "false"

It is the by default state of controls which can perform Postback on button submit.
