.net - Listview Paging Without Havind All Records In Memory?
Nov 9, 2010
In my asp.net page I have a listview that has a datapager defined in the LayoutTemplate.The listview is databound to a list of records. I know the total number of records ... but I don't load them from the db. I want to tell the pager at first request the total number of records and let it generate the pages and navigation. When the user click a page from the datapager I want to load the records from the db and update the listview binding to display results from that page. Is this possible with the listview and datapager from asp.net?

I have custom paging for a grid with first next prev last. My issue is with current code it takes a lot of time for post back & going to next page & displaying records, even page loading takes time, so I needed to load the records on request....
Means suppose the pagesize is 50 records per page on initial page load only 50 records will be displayed from database instead of all say 2000 records & then when user clicks next next 50 will be loaded from database to grid & so on .....

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 cancelled.
I currently perform the validation in the PagePropertiesChanging event of the ListView, however, the arguments do not provide a Cancel property.
protected void MyListView_PagePropertiesChanging(object sender, PagePropertiesChangingEventArgs e)
{
if (!Validate())
{ // cancel the paging action}
}

I have two gridview. The first gridview with checkbox and if i check the checkbox in first grid that particular row will be binded to second grid. In second grid i have a textbox and dropdown. Have enabled pagination in both grids. When i check the checkbox in first grid i loop through all records in second grid to bind the previous values. Problem is since i have enabled pagination gridview row count only retuns current page row count. How to loop through all rows?.

I have used a GirdView to display data from database, data would be huge around 670 rows. And also I want to display all data together on single page.
Therefore I want to use virtual page scrolling. Means on Page load only 20 rows would be displayed, then when page would be scrolled next 20 rows would be displayed.....

I have a simple page that looks up contacts using a webservice with a single method written in Linq. On the page, I have both a gridview and a listview with a DataPager to compare the two. I can get paging working just fine with the gridview, but the Linq code has to return all of the data on each call and let the web page pick out only a page's worth... not the best solution. I have been told that a ListView will solve this problem, but all the examples I have been able to find have the Linq code on the web page instead of in a separate layer (e.g. a webservice). Ideally, I should be able to tell the web service to bring back a specific page worth of data (starting record number and number of rows), but how do I get the ListView (or the DataPager) to fire an event that asks for this data?
Here is the ASPX code:
<asp:ListView ID="listPersons" runat="server"> <LayoutTemplate>
<table> <thread> <tr> <th> Site ID </th> <th> PersonID </th>
<th> Person Name </th> </thead> <tbody>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" /> </tbody> </table>
<asp:DataPager ID="Pager1" runat="server" PagedControlID="listPersons" PageSize="5" > <Fields>
<asp:NextPreviousPagerField ShowFirstPageButton="true" ShowPreviousPageButton="true" ShowNextPageButton="false" ShowLastPageButton="false" /> <asp:NumericPagerField />
<asp:NextPreviousPagerField ShowFirstPageButton="false" ShowPreviousPageButton="false" ShowNextPageButton="true" ShowLastPageButton="true" />
</Fields> </asp:DataPager> </LayoutTemplate> <ItemTemplate><tr> <td> <%# Eval("SiteID") %>
</td> <td> <%# Eval("PersonID") %> </td> <td> <%# Eval("PersonName") %> </td>
</tr> </ItemTemplate> <EmptyDataTemplate> No data found... </EmptyDataTemplate> </asp:ListView>
Here's the code behind:
private void DoList(string Match) {
ContactsService cs = new ContactsService();
listPersons.DataSource = cs.Find(Match, 100 ); listPersons.DataBind(); }
and the web serivice:
[WebMethod]
public List<Person>Find(string Match, int Count) { if (Count < 5) Count = 5;
using (DataLayer.ContactsDataContext context = new ContactsDataContext()) {
var Persons = from p in context.Persons where p.PersonName.Contains(Match)
orderby p.LastName, p.FirstName select new Person() {
SiteID = p.SiteID, PersonID = p.PersonID, PersonName = p.PersonName, };
return Persons.Take(Count).ToList(); } }

I have a listview nested inside a gridview.
I'm trying to get paging working on the listview. I thought that it would display the paging controls, and just page through them normally.
It does display the controls, and limits the result set shown to the appropriate number of records (pageSize) but when I click on the paging controls the grid refreshes and nothing changes with the nested listview (it's still on the first page).
I've tried nesting the listview inside an updatepanel, but the behavior remains. The gridview itself is already in an updatepanel.
So this is the layout I've got:

I was wondering if there were any decent tutorials on paging the records in a ListView using a DataPager (Pager Control). I can get it to work with Drag and Drop but I can't seem to find a decent tutorial on doing it programmatically.

I've got a big problem here with the ListView control. Basically I've got very basic code, yet it seems to break the control completely.
Here's the deal, I got a simple ListView using an ItemTemplate containing a hyperlink. Obviously the hyperlink has to lead somewhere after clicking, so the datakeys enter the scene since I need to hook up a hyperlink containing the Id of the record it's in as a parameter.
Normally this shouldn't be a problem, so in the itemcreated event I look up the link control and add the url using data foud in the datakeys.So far so good, this all works out fine.
Now this contains a number of records, too many to display on one page, so I decided to implement paging by using a DataPager, which is the way to get the ListView to support paging. This didn't work.
After a little tinkering around with the code, I found that if I didn't get any datakeys in the itemcreated event, that it all works fine. However, I need to use the datakeys or I won't be able to hook up a url to the hyperlink.
Basically, that one line of code completely kills paging. Commenting it out immediately sets things right, but that's not an option.

If I disable the ViewState on a ListView, the events raised by it are no longer ired. OnPagePropertiesChanging is the ListView event I've always used in combination with the DataPager to update the ListView to the correct page once a DataPager item is clicked, but since its not being fired, I'm wondering if there are any other options. My ListView is currently in an UpdatePanel, and I'm caching the results that the ListView is being bound to. I could rebind the cached results on the PageLoad, but I can't think of a good way to determine if the PageLoad is being accessed because the DataPager was clicked, or for some other reason, so this doesn't seem like a good idea

I have a ListView control that makes use of a DataPager. In each row of the ListView there is a text box where the user will enter some notes relevant to that particular record. Then they use the DataPager to navigate to the second page of records. If they then return back to the first page in the ListView the text they entered is gone.
Question: Is there a way (through use of a paging event or databound event maybe?) to retain the textbox values between paging events ?
I would like the user to be able navigate backward or forward and still see the text heshe has entered.

so instead of a datasource control, I have a Data Access class that I'm using to populate the ListviewI added a datapager and everything pretty much works until I hit the first or last button. Then, I get the following error: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/>Also, Something was mentioned about ClientScriptManager.RegisterForEventValidation - - couldnt' really find an implementationI tried setting:EnableEventValidation="false", but then, all I got was squirelly interaction with all the numbered links (sometimes having to double click them, etc) - no matter what I tried from there on out, even when I removed the enableEventValidation property altogether.
