Hello Irri,

There is property called “PageIndex” that controls the index of the page shown in pager initially - http://help.infragistics.com/NetAdvantage/ASPNET/2012.1/CLR4.0/?page=Infragistics4.Web.v12.1~Infragistics.Web.UI.GridControls.Paging~PageIndex.html

You can set it in designer or from Code-Behind like this:

protected void Page_Load(object sender, EventArgs e)

{

   WebDataGrid1.DataSource = GridDataSource();

   WebDataGrid1.Behaviors.Paging.PageIndex = 2;

} 

I hope that this property will be useful in your scenario.
