Hi all,

I have a custom user control used to handle the paging of the whdg.

During a change in the custom pager a post back is initiated.

According to the stack trace (which is included in the attached sample) 'Object reference not set' error is thrown during the GridControls.ContainerGrid.DataBind().

I have not been able to track the reason for this as the grid's datasource is set on every post back.

It seems that after the OnPreRender of the page, the controls fire a OnPreRender event and during this process it seems that this are going wrong.

I have attached a sample reproducing the issue.

Steps to reproduce:

1. Run application

2. In the GridPager  "Views" dropdownlist, select Red Records.

My environment is as follows:

 VS2010

IE9

Widows 7 32 bit.

Infragistics ASP.Net Version 11.2.20112.2086

.Net 4

The grid is located inside a WebTab.

Regards,
