So I have a grid with 10 pages. I am on page 5. I refresh the grid because my actions might have caused a number of rows to disappear. When I get the data and rebind, how do I go the the last page I had selected? I want the grid to be on page 5 after the refreshing of the data.
this.WebDataGridView.Behaviors.Paging.PageIndex I think this has what I am looking for.
this.WebDataGridView.Behaviors.Paging.PageIndex
I think this has what I am looking for.
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?
Hello mland,
you should be able to change page index on a button click. What is your datasource?
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.

try with this:
protected void Button1_Click1(object sender, EventArgs e) { WebHierarchicalDataGrid1.GridView.Behaviors.Paging.PageIndex = 2; }
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?
