Property Value

Type: System.Boolean
true if the client position should be maintained; otherwise, false.

When Web pages are posted back to the server, by default the user is returned to the top of the page. On long Web pages, this means that after a postback the user might have to scroll back to the most recent position on the page.

When the MaintainScrollPositionOnPostback() property is set to true, the user is instead returned to the most recent position on the page.

You set the MaintainScrollPositionOnPostback() property in the @ Page directive.

Error Occured during Compilation of the Code : Object reference not set to an instance of an object.

Dim instance As Page
Dim value AsBoolean

Dim instance As New Page

instead of

Dim instance As Page




History
Cross browser functionality of MaintainScrollPositionOnPostBack

Property works in IE6/IE7 for me while it fails at the same time in Google Chrome 0.2 and 0.3. So perhaps cross browser functionality of this property has not been completely and fully tested.

A little problem with MaintainScrollPositionOnPostback
This doesn't seem to always work when wordwrap is enabled in GridView columns; the position seems to be calculated as though no wordwrap were taking place.
History
MaintainScrollPositionOnPostBack

This property does not apply to controls (example ListBox) added to a User control. If the attribute is set in the page directive to where the User Control resides or in the Web.Config file it does not maintain the state of position after a full or partial postback.
