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
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.
I have a webform which uses a gridview control to show result of a search operation.I wanna to take advantage of using pagination in the webform. But as you all know, gridview pagination is a client-side pagination and it transfers all records have been selected to the client. What I mean by client-side pagination is the client (page) shows records page by page but every time the user clicks on a page link to navigate through records, all the records are selected from Data Source.How can I use gridView with datapager in order to have a server side pagination? Or any other solution to get records page by page by configuring our query?
i want to apply datapager control to my server side table. i fill record in it and now i want to apply datapager to that asp.net table. How i can do it.
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 am trying to implement server side paging with gridview using coding by DAL and BOL concept.But the Problem is with the Gridview page index.As the No of rows retrived are equal to page size and hence I am not able to genearate pager information .I cannot use object data source as i have 2 generate this on some event by passing some arguments like button clickPlease let me know how can i resolve it.Can i use datapager,Or do i need 2 create custom hyperlinks or any alternative to display gridview page index.
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.
i am applying paging in list view. i used data pager control. but problem is on click of next page next data is not displaying only showing previous data. i have one dropdown i am bing list view on dropdownindex change event not in page load.
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 am passing the PageNumber and PageSize to a stored procedure, which returns only that page of data. It also returns a record count what the total number of records would be if I returned all of them at once.Generally, how do i hook this up to the DataGridView to enable paging?It seems like the expectation is for the resultset to contain the complete dataset. Many of the properties that I expect to be able to set, like RecordCount, appear to be read only.
Regarding ASP.NET's GridView server control: Can I bind to a datasource in the code-behind, load the entire resultset, and then implement client-side paging without postbacks? If this isn't possible with GridView, I'm willing to implement a custom solution. EDIT: My GridView instance sits inside of a nyroModal (jQuery) pop-up div, which is why I need a non-postback solution.
i have a listview to show some data and with it i have a datapager the datapager is used for allowing change pages between products but i have and hyperlink above product image that allow to see the specific product details but the datapager wehn a used clicks to see product details should not be visible because there is no more pages , its a specific product but the datapager should be visible in the other scenario how can i do that?
I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
I reordered some items in a listbox using Javascript. When I read the items in a postback in the code behind (ASP.NET), the order is in the original order. How do I get the same order as shown in the screen after Javascript manipulation?
I m using site login Control in my login.ascx file and disaplaying login control in Div so if there is login link in page and i click on that then Login Div will popup which is site login.May i know how can handle error like username or password is incorrect on client side instead server side?
I have to implement the print functionality on aspx page like on click of print image icon user will be able to get the print out of aspx page .aspx page will contain the server controls like textboxes , Gridview etc which one approach will be the best server side or client side printing ?
