I am having trouble finding how to solve the following issue :
I am using nested listviews to display Sales and Sales details.
The main ListView displays General Information about Sales and the child ListView displays the detailed information about one sale. the child listview is shown only when the user clicks on a link (see included code, DataBind is made on PageLoad) :
ASPX Markup Code :
[Code]....
C# Behind Code :
[Code]....
If I removed the datapager part, I can manage show/hide the child list view on the button click event. but if I want to use the DataPager with the PreRender event handling, the child listview is not longer shown on button click.

I have a listview and a datapager for it c outside of the listview. I would also like to add a datapager in the GroupSeparatorTemplate. I have added it, but when I try to go to the next page of the ListView the page takes a long time to do the postback and, at the end, it doesn't go to the next page.
<div id="paging">
<div>
<span><asp:Label ID="lbl_paging" runat="server" EnableViewState="false"></asp:Label> </span>
<asp:DataPager ID="dpAccommodations" runat="server" PageSize="6" PagedControlID="searchresults" EnableViewState="true" QueryStringField="page">
<Fields>
<asp:NextPreviousPagerField ShowNextPageButton="false" ShowPreviousPageButton="true" ButtonType="Link" PreviousPageText="Prev" NextPageText="Next" RenderDisabledButtonsAsLabels="true" RenderNonBreakingSpacesBetweenControls="false" ButtonCssClass="prev"

<asp:NumericPagerField ButtonType="Link" CurrentPageLabelCssClass="pager" RenderNonBreakingSpacesBetweenControls="false" NumericButtonCssClass="lala"/>
<asp:NextPreviousPagerField ShowNextPageButton="true" ShowPreviousPageButton="false" ButtonType="Link" ButtonCssClass="right on" NextPageText="Next" RenderDisabledButtonsAsLabels="true" RenderNonBreakingSpacesBetweenControls="false"/>

I have a listview where it's content is from a datatable. Programmatically, when the user goes to the webpage, the listview is binded to a datatable like so:
[Code]....
I want to now add a DataPager but this code isn't working:
[Code]....
Clicking on the page numbers either has no response or clears out the listview or distorts the data.
What can I do to make DataPager behave correctly?

I have a Listview Control and the paging is implemented using the DataPager control.
I have set the maximum pagesize=5 of the datapager.
But when I click the next or previous buttons it loads the same set of products, no matter how many times I click on the next/previous buttons,

And here is the code behind file
using System;
using System.Collections.Generic;
using System.Linq;

environment: VWD 2010 Express, SQL 2008 Express, .NET 4.0, VB
I have a page with 4 radio buttons followed by 3 cascading ddl followed by a tab container with 5 tabs. Each tab holds a listview, etc that is particular to the group that has access to that tab. On page load I filter the listview based on who is logged in plus which radio button and DDL is selected - all ok so far.
after the page load, the initial datapager works fine and all other listview functions are fine. However, if I select the 4th radio button, the data returned is correct and the datapager shows as if it knows the correct number of items but if I click the datapager page 2 (or Last, etc) it immediately reloads the correct data as if it were a new page load (and changes the datapager appropriately). My suspicions are that this is due to the declarative select command defaulting to the data that it always goes back to.
I have tried to move the select to the code behind and played with the tabcontainer prerender event. That eventually got me to the point where the datapager was working properly but then I could no longer edit any of the dropdowns in my listview edit screen where I could before. They would go through the motions but as soon as you selected a new dropdown value, it would revert back to whatever it was before.
So at this point I'm looking for ideas on how to make these work together.
the code is excessive so I will avoid that for the moment until I can whittle it down to what is pertinent

I have a page (with a master page) with a listview and a datapager on it.The datapager is under the listview in a div element.For some reason, when the page is rendered, the datapager is rendered out side the ContentPlaceHolder of the master page and I get a large space that shouldn't be there.I also have a datapager on my master page. Does it matter?

I have a page where I use the ListView and DataPager.My listview is populated as a table where each row has a bit data a dropdownlist with some values and a link button. Now I am trying to pick out the selected value from dropdown list when I kick on my linkbutton. As long as I'm on page one, everything is woriking fine. But if I go to page three then I can not pick out the value I selected in the dropdownlist. I have tried to add a textbox in the listview and then I am able to get the value out I typed into the textbox independent which side I'm on.
Why can I pick out the value from textbox but not the selected value in dropownlist?

I'm using a datapager control on my listview to perform paging in it.When paging through the table, I need to perform some validations. When these validations are not successfull, the paging should be cancelledI currently perform the validation in the PagePropertiesChanging event of the ListView, however, the arguments do not provide a Cancel property.

I have a listview control which is created dynamically, it is nested inside a repeater's itemtemplate. I'm trying to attach a datapager to it, which is also created dynamically but the datapager will not display and the listview will just display all its records in its entirety.

There have been a few datapaging questions tonight, but mine is a bit different..
I have a regular datapager, in a seperate project it seemed to work fine with the same query and templates, but when I use it in my page, whenever the I try to page I get the emptydatatemplate when there should be data..
Here is my current ListView
[Code]....
I have tried binding data OnPreRender and setting the page properties under the OnPagePropertyChanging events.. still only getting my empty template whenever i navigate through the pages when there should be plenty of data..

When (in what event) is the best time to set PageSize for the ListView's DataPager? I have tried every event on the ListView and either it does not work (i.e., reverts to the default 10) or I get a CRASH of some sort (mostly error 12002) - but that's a different story.

I have a ListView that uses an ObjectDataSource
When I add a DataPager control INSIDE the ListView, it works fine and the ListView's PagePropertiesChanging event fires.
When I move the DataPager OUTSIDE the ListView control and set its PagedControlID
to the ListView, it stops working and the ListView's PagePropertiesChanging event no longer fires.
i.e. This works (and the ListView's PagePropertiesChanging fires):

I have ListView control on my page, and i bound it to Dictionary<string,DataTable> generic.Now i'm trying to put DataPager on my page to support paging, but DataPager doesn't work properly, in particular, I have to click twice to move to next page, or first few records repeating thru every page. What's the problem, what am I doing wrong? I used ListView control before with ObjectDataSource and it worked just fine. Now I'm using Entity Framework to retrieve data frm Db.

i have a listview (table layout) bind to a sqldatasource (sqlprocedure) with a datapager for custom paging and custom sorting using linkbuttons.
The problem is, if i click on a linkbutton to sort, the datapager jumps always to the first page.
Is there any way to keep the current page on sorting?
I tried DataPager.SetPageProperties() on sorting event, but it doesn't work.

To Start with, I am new to .NET. So I am not refer to the right word, but I'll write up whatever I can.
Basically I have 3 input fields and then a search field.
When I hit the Search field, based on the 3 inputs, it needs to get the DataSet and fill it in the ListView.
I believe it is doing it. But when I added the DataPager, it lists only the first 10 rows, even if hit NEXT
Here is the code ib the .aspx page to populate the ListView
asp:ListView
ID="FISIItemsList"
ItemPlaceHolderID="ListFISIItems"
Since the NEXT button is not working, I thought of Adding the DataSet to a Properties. The and getting it back.So I did something like
public
DataSet
dsFISIItems[code]....
Even this doesn't work.
In simple terms, > After the 3 input fields are filled out, when a "Search" Button is hit, it should go and pick the list of items based on that criteria
> The result dataset needs to be binded to the ListView
> Next, the DataPager control should be paging. But it is not paging.
When I hit the next, it lists only the first 10 items repeatedly.

I've been trying to marry up the listview and the Data pager with my own, Database class that pulls the information from the database.
I can display the information ok no problem, fortunately this time I know what the problem is, but I cannot figure out a way around the problem.
In my Page_Load event I fill out the listview accordingly:
[Code]....
The problem lies in the postback, I need to figure out a way get the information as to what state the DataPager is in so I could update the Query accordingly.
I know there is a StartRowIndex avaialbe but this does not get updated in the Page_Load event.

I'm using a ListView (e.g topListView) with paged rows (using a DataPager). One of the topListView's features is when a user clicks on one of its rows, its SelectedValue property is used to populate a SelectParameter in another SQLDataSource control that populates another ListView (e.g. bottomListView). It's working fine. Even when the webpage first loads, the SelectedValue of first row of the topListView is successfully being used to generate content in the bottomListView.
However, when one of the DataPager's buttons is clicked, the SelectedValue seems to be ignored, and the bottomListView isn't refreshing. And yet, when you click a DataPager button again, it works. basically it's taking TWO clicks of the pager for the SelectedIndex to be read. I've tried assigning the SelectedIndex to 0 in the PagePropertiesChanged and PagePropertiesChanging handlers but no luck (even with calls to bottomListView.DataBind(); and/or SQLDataSource1.DataBind(); after index assignment).
assigning the index seems unecessary though, since top row content is being rendered correctly in a SelectedItemTemplate after clicking any DataPager button. to me that means the SelectedIndex is being set to 0 when the page is being re-rendered.
