ListView pagination problem.

[George Ter-Saakov]

Trying to quickly create paginated grid. So i am using ListView.
Unfortunatelly pagination works a little strange.
Pagination control appears correctly.

But when i click "2" page postback happens but current page is still first
page. Then i click "3" page. Postback happens but current page is now "2"
page. Then i click "4" page and again postback happens and page 3 becomes
current.

Why is that? How to make it work?
Bellow you can find my code (Nothing else like code or any other control is
on the page)

thanks
George.

protected override void OnInit(EventArgs e)
{
if( !isPostBack )
{
grdItems.DataSource = clsGlobal.GetData("SELECT Id,Name FROM
tblMy");
grdItems.DataBind();
}
}

<asp:ListView ID="grdItems" runat="server" DataKeyNames="ID">
<LayoutTemplate>
<table>
<tr class="gridheader">
<td class="gridheadercolumn">Id</td>
<td class="gridheadercolumn">Name</td>
</tr>
<tr runat="server" id="itemPlaceholder"></tr>
</table>
<aspataPager runat="server" ID="DataPager" PageSize="3" >
<Fields>
<asp:NumericPagerField ButtonCount="5" PreviousPageText="<--"
NextPageText="-->" />
</Fields>
</aspataPager>
</LayoutTemplate>
<ItemTemplate>
<tr class=griditem>
<td class="griditemcolumn"><%# Eval("Id") %></td>
<td class="griditemcolumn"><%# Eval("Name") %></td>
</tr>
</ItemTemplate>
