datagrid paging not working

[ponstan]

Hi

I have a page with a search button & a asp datagrid with paging enabled. In IE8 the grid displays correctly when I click the search button. But when I click on page 2 for example, the grid goes blank.

Now, when I hover the cursor over the page2 link, i notice the doPostBack is missing the second parameter.

eg: javascript: _doPostBack('ID$controlID$mygridID, '').
Isn't it supposed to be javascript: _doPostBack('ID$controlID$mygridID, 'Page$2') or something like that? Where's the 'Page$2' param gone?

in the ASPX:

<aspataGrid id="mygridID" AutoGenerateColumns="False" EnableViewState="true" runat="server" AllowPaging="True" PageSize="5">
<Columns>
<asp:BoundColumn HeaderText="Name" DataField="Name"/>
'etc..a few more columns
</Columns>
</aspataGrid>

In the properties-events of the grid I tied the PageIndexChanged event to the code below:

Protected Sub mygridID_PageIndexChanged(ByVal source As Object, ByVal e As DataGridPageChangedEventArgs) Handles myGridID.PageIndexChanged
Dim ds As DataSet
ds = Cache("dataset") 'already retrieved and cached the data in my search button method.
myGridID.DataSource = ds
myGridID.CurrentPageIndex = e.NewPageIndex
myGridID.DataBind()
End Sub

If I replace the Datagrid with GridView doing basically the same thing it works, but I would like to know why my Datagrid paging doesn't work...I've gone through forums, articles etc for a few hours, but don't see any dealing with missing doPostBack param, or is it something else I missed?

I'm using MS visual studio 2008 with .Net 3.5 SP1.

any help is appreciated.

Thanks.

Ok turns out the event wasn't firing properly.

I had to do a if not Page.IsPostBack in the page_load, then rebind the grid there as well.
