How To Perform Server-side Pagination By Using A GridView And A DataPager
Feb 20, 2010
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?
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 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.
Now I must run cmdSave_Click() before the cmdConfirm.Attributes.Add even though both is for same button anyway. I know that client side script will try to run first but I must run the cmdSave_Click event first to save the data. Aftre that cmdConfirm.Attributes will send the Name to the next page using a Javascript function where the stored values(stored using cmdSave_Click) will be used. I have no other choice. I cannot run the Javascript function first as it will happen before the data is stored. And also I cannot use another page as all has to be performed in one page so that user will not have to click Save twice. Can anyone tell me How I can delay the cmdConfirm.Attributes.Add until the cmdSave_Click is performed.

I am trying to implement pagination in my gridview control. Here is the code for databind and pageindexchanged
Private Sub BindGrid() Dim dataTable as DataTable = CType(Session.Item(APPLICATION_DATA), DataTable) Grid.DataSource = dataTable.DefaultView Grid.DataBind() End Sub
Protected Sub OnChangePageSize(ByVal send As Object, ByVal e As GridViewPageEventArgs) Handles Grid.PageIndexChanging Grid.PageIndex = e.NewPageIndex _BindGrid() End Sub
But I get error after Grid.DataBind() as "Unable to cast object of type 'System.EventArgs' to type 'System.Web.UI.WebControls.GridViewPageEventArgs'"
I am trying to hook up custom pagination with an ObjectDataSource to my GridView. However, this thing renders no data, but does render the column headers. The debugger clearly indicates a populated DataTable being returned.
my gridview shows multiple repeated pages for one page and I dont know from where come the problemand im treating the event of the paging well
Protected Sub GridView1_PageIndexChanging(ByVal sender As Object, ByVal e As GridViewPageEventArgs) GridView1.PageIndex = e.NewPageIndex If lstCustomer.Visible = True Then
I'm a asp.net newbie trying to figure out how to do the following. I have a datatable. I want to extract the first row and perform a certain operation and a different operation on the remaining rows. How would I loop through the datatable to do this?
I have created a website that has some gridview controls that call stored procedures in a SQL db and display the results of the procedures. Two of the gridview controls have sorting enabled, and one has pagination enabled.
The site loads for all users who have tried it so far.
However, one user gets a "webpage not found" (HTTP 400 Bad request) error whenever they click on the pagination links or sorting links on the gridview control. It seems like it's not a security issue because the website runs as a user with permission to the database.
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?
Is there a matching client side event that is fired before or after OnPageIndexChanging is raised? Such as the OnClientClick, I would like to append a script when the paging numbers / arrows are clicked. Is it possible, of so; how?
