LINQ and ListView problem

[shapper]

Hello,

I have a ListView where I use LINQ for data, for example, selecting,
and deleting.
In the ListView item template I added a DataPager.

When I click, for example, "Next Page" or a page number in the
DataPager something strange happens:
It always takes me 2 clicks for the action to be taken.

The only thing that solves this is to move the code I have in my
ListView Load event to the ListView PreRender event.

Please, does anyone has any idea what I am doing wrong?

Here is my ListView code:

Private Sub lvTags_Init(ByV al sender As Object, ByVal e As
EventArgs) Handles lvTags.Init
lvTags.DataKeyN ames = New String() {"TagID"}
lvTags.ID = "lvTags"
lvTags.ItemTemp late = New
TagsTemplate(Te mplateType.Item Template)
lvTags.LayoutTe mplate = New
TagsTemplate(Te mplateType.Layo utTemplate)
End Sub
Private Sub lvTags_Load(ByV al sender As Object, ByVal e As
EventArgs) Handles lvTags.Load
Dim database As New CodeDataContext
Dim tags = From t In database.Tags Select t.TagID, t.Text
lvTags.DataSour ce = tags
lvTags.DataBind ()
End Sub ' lvTags_Load

And my DataPager code which I add inside the ListView ItemTemplate
implementation is:

Private Sub dpTags_Init(ByV al sender As Object, ByVal e As
EventArgs)

Dim dpTags As DataPager = CType(sender, DataPager)

Dim field As New NextPreviousPag erField
field.FirstPage Text = "<<"
field.PreviousP ageText = "<"
field.NextPageT ext = ">"
field.LastPageT ext = ">>"

dpTags.ID = "dpTags"
dpTags.PageSize = 8
dpTags.Fields.A dd(field)

End Sub ' dpTags_Init

Thanks,
Miguel

Try moving the Datapager outside the Listview ItemTemplate. You should be
able to put it anywhere on the page, and set the PagedControlID to your
ListView
