So that works great on a button click.  I tried to move it into Page_Load event. I am trying to set the page if it is a postback

           if (!IsPostBack)

            {                

                this.RequestGrid.DataBind();

                
WebHierarchicalDataGrid1.GridView.Behaviors.Paging.PageIndex = 2;

            }

On my demo grid this worked great.

On my real grid I got an error, I turned off tracing and it worked.  Seems a little odd.

Multiple controls with the same ID 'grdOffRequests:_ctl0:it1_0' were
found. Trace requires that controls have unique IDs.

Description:

request. Please review the stack trace for more information about the error and
where it originated in the code.

Any thoughts on the code I posted

So here is my test project.  On the button I have:

WebHierarchicalDataGrid1.Behaviors.Paging.PageIndex = 2;

I would have thought this would work but…         Any suggestions?

            Id_l = 0;

Ah…  Not as easy as it first looks.  I looked at a couple of other post and can get the current page number.  I do it with a hidden control on the client.  Now I need to set the page index.    I tried on a test button on the form that sets the DataSource and I call  DataBind().  I then try to set the pagIndex

.Behaviors.Paging.PageIndex

this nas no effect.  Where should I do this?
