I have a listview control and a datapager control in a ascx page, this is then embedded in the aspx page.
When my page loads the records come up, and the page numbers appear in the pager, however, when I click on any of the page numbers, the page is always blank, no records.
Im pretty confused on this and would appreciate any suggestions.Im trying to implement custom paging because my database has some 400,000ish records and i want to show 20 at a time in a gridview. I don't want to use a datasource in the html because this gridview gets populated using a dataset in the .cs (c#) because
the user first filters on params. I have two sp (on to get the total record count and one that filters). Both sp work.

Does anyone know how i can tell my gridview (and if i need to implement a datapager) the total number of records, to get the page numbers on the bottom correct and then pass the parameter @PageNum @PageSize@sortExpression?
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 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.
View 1 RepliesI have a usercontrol with a datagrid that is used throughout my web application. The datasource is passed in a public method from the master page to this usercontrol, as the data selection is different on each page where this usercontrol is used.But by doing this, I'm having a problem with paging, as the datasource is lost after postback. I can't do the data selection in the usercontrol itself as the dataset is passed as a parameter.

View 2 RepliesI'm trying to use a DataPager to do Server Side paging. Here is my code
<asp:DataPager ID="pgrFooBars" PagedControlID="lvFooBars"
QueryStringField="page" runat="server" >
<Fields>[code]....
The problem is that the DataPager appears to be using the Count property of the ListView to determine the total number of records, which in this case is 20. Somehow, it needs to know that there are 1,500, not 20 total records. The DataPager has a property TotalRowCount, but this is read-only.I have never seen a DataPager example with Server Side paging, but assumed that it could do Server Side Paging, otherwise what good is the QueryStringField attribute?
I am aware that you can do a custom paging solution using methodology like the 4GuysFromRolla did here http://www.4guysfromrolla.com/articles/031506-1.aspx, but I'd first like to know if a solution with the DataPager is possible before creating a custom solution.
UPDATE,The more I look at this, the more that I'm coming to the conclusion that this is not possible and that, unfortunately, the datapager is a control meant for small web sites only. What I want to do should really be quite simple if the control were built correctly. I want to be able to say
dpFooBars.TotalRowCountComputed = false;
dpFooBars.TotalRowCount = AnyNumberThatISoChoose;
I've been looking for some hack to accomplish the same thing, but it appears that the datapager's TotalRowCount is computed from the actual number of items in the datasource that it's bound to. It seems very odd to me that Microsoft would create a ListViewPagedDataSource() class and a DataPager at the same time and not have them work correctly together, but this appears to have been what has happened.
UPDATE 2 (AHA MOMENT?It seems that it has been possible to do server side paging since .Net 2.0 by using an ObjectDataSource and customizing the SelectCountMethod(). I believe it should be possible to customize ObjectDataSource to suit my needs. Hmmm. I'm going away for the weekend, so it'll be a couple of days for me to see if this works. Stay tuned, true believers.

View 2 RepliesHow to use datapager with gridview in asp.net 4.0 ?
View 2 Repliesis there any chance to set DataPager width to 100% or to a static width of some px?
View 2 RepliesI have just downgraded 2 of my asp.net projects from framework 4 to framework 3.5. It looks like the latest framework has broken the datapager functionality. I consider this a pretty fundamental part of presenting data to the UI. Has anyone else experienced problems, and does nayone know when Microsoft will fix the problem. In my case when paging away from page one and then changing the page size via a dropdownlist (see below) all work fine.
If navigating to the last page and then selecting some more search criteria to perform another search the pager returns no records found, the record counts etc hold the previous search result counts and it is not until the search button is clicked again that the expected results are rendered.
All works correctly now, as intended after reverting back to framework 3.5.

I have a Listview with a Datapager. The Data pager is inside the listview LayOutTemplate, and works fine when there are records to page.
Now the problem is that the Datapager shows even when there are no records to show. (the navigation is disabled).
it shows something like Page
0 of
0 (
0 records).
For example, in my sample application, I have set the Pager size to 10, but I have ZERO records. Idealy, I only want it to be visible
if the number of records exceeds the pager size. How do I do this?
I have a listview control qith a datapager. I'm using a linkbutton for next and previous. I have a css class that makes the text Arial, and bold. It also sets the size to 10px. When I run the page, the link button is Arial and bold, but I can't change the size of the text. I've tried setting it to 10px, 8px, even 5px, 10pt, and xx-small. Nothing changes the font size. My customer wants the next and previous buttons to look a certain way. I'll have to manage paging manually if I can't get this figured out.

I have a listview in a page and I use a DataPager to do the paging. Each time the user clicks a page's number, the page does a postback and it shows the next "x" items. My problem is that I rewrite the url with isapi rewrite and when the user is being redirected to the second, third etc page of items the friendly url is being replaced by the non-friendly url of the page.

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,

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
