I have a listview that I'm binding programmatically. I am trying to add a simple datapager but the paging is not working. it is because I am binding programmatically.
[Code]....
So I am using EW + Access database to create a page.
This page contains two controls. First control is Dropdownlist which databinds with second control Listview.
This listview has paging on becuse of multiple pages. If I don't use QueryStringField paging works but if I use QueryStringField paging doesn't work and it goes back to first option of Dropdownlist.
I have a listview and would like to scroll the ItemTemplatei instead of using paging. I need to freeze the header and InsertTemplate row, and works accross browsers. I've tried the following link:
[URL]
but am having problems getting it to work accross browsers I can get it to work in FF or IE6 but not both.
is there another control rhat's more suitable for this than the ListViiew?
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'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'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
View 2 RepliesI 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.
View 7 RepliesI have a question regarding the listview control paging and preserving the state of the items on page change.
I am using listview control and datapager control to achieve paging in the listview control.
I use the listview to display list of questions like with radiobutton list options as answers...
I am unable to preserve the selection of answers between the page changes..
for eg : I If select option1 for the question1 and move to a next page. and If I come back to previous page, the selection goes.
I tried using the view state...but could get this working..
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 have 3 gridview in my homepage..each one dealing with many rows.
I'm allowing paging in all 3 but its now working
Here's one of the codes:

Why is the auto paging not working for me? Is that because it only works for BoundField? Mine is mostly
templatefield. Other than auto paging, everything else works fine. I have at least 20 rows, so once I
specify AllowPaging="ture" and PageSize="5", it should give 5 rows a page for 4-5 pages, right?

I published my application into server. Some reason gridview paging is not working when i open the application from the server.
Note: When I ran the application at my local system using VS-2008 it's working fine.
I have a gridview within an updatepanel which allows paging and has a linkbutton that when clicked shows a modalpopup for editing records. This works fine in IE, Firefox, and Opera but I do not get a postback in Chrome or Safari?? I have other linkbuttons on the page that are within updatepanels but are not within gridviews that are working fine. I have scowered the web but cannot find a solution.

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,
