Forms Data Controls :: Gridview Paging - Pages Won't Display
Apr 19, 2010
I am trying to figure out why it won't display the other results when I click on the second and third links created by enabling the paging option the gridview control. it wasn't displaying properly.. also it may not make a lot of sense.. I'm a PHP programmer... I'm learning asp.net as part of a class and we're instructed to use the drag-and-drop method so forgive me, my asp.net skills are lacking and I am having a hard time learning it. Anyway I'm reposting the current code.. hopefully it will display properly this time. Here's the code for default2.aspx..

I have a web app where everytime I upload an Excel file, its contents appears in Gridview, which is binded with a DataTable. Using the properties, I have set paging and sorting to true.
When I input a file using fileupload and a submit button, the web app has page numbers at the bottom appear.
It also correctly sorts it, (my page size is set to 10), however, when i click on the next page (pg 2, for instance), nothing shows up until i upload the file and hit submit again.
This is the code in which I build the table:
protected void AddResultToGrid(String url, String result)
{
data = (DataTable)Session["URLSessionData"];
DataRow dr = data.NewRow();
dr[0] = url;
dr[1] = result;
data.Rows.Add(dr);
gdvResults.DataSource = data;
gdvResults.DataBind();
Session["URLSessionData"] = data;
}

I reviewed the previous article on a similiar subject, but it was more for C+. I have an Access db feeding a Gridview control, with the defaults of 10 records per page. I know there are more then 10 records for the information I searching on, and pages 2 & 3 are listed in the 'paging' feature in the header. By the way, my page is results.aspx.
Clicking on page 2 results in no additional results being displayed. I understand a little from the other post, that Gridview tied to Access will not automatically show results past page 1, without some additional coding changes.
<asp:GridView runat="server" id="GridView1" AutoGenerateColumns="False" DataSourceID="AccessDataSource1" CellPadding="3" AllowPaging="True" AllowSorting="True" BorderStyle="Solid" BackColor="White" BorderColor="#70C8D0" BorderWidth="1px">
<PagerSettings Position="Top" />
<RowStyle ForeColor="#000066" Height="30px" />........

2 Naheed mart 11/12/1991 4000
3 Imtiaz Super Market 11/12/1991 3000
Now it must group by the company name and show running total and net total like :

I have read your article from aspsnippets.com about custom paging it really work, but there are a problem that if there are more record in database (2000 to 5000) than number of page index will be goes in large number. like 1 to 200, any way which can divide it like 12345678910...2000.

I want to use a gridview with sorting and paging to display data from an SQL server, the query uses 3 joins and the full text search containstable. The from part of the query uses all 3 tables in the join.What is the best way to do this? I can think of a stored procedure, SQL directly in the SQLDataSource and creating a view in the database.I want good performance and would like to leverage the automatic sorting and paging features of the gridview as much as possible.
Edit:About size, I suspect very few records, total about 1000 and a query would typical result in no more than 100 records and most times much less.

we have a classic ASP Webpage for displaying reporting data.
The process is following:
user inputs reporting criteria reporting criteria are passed to a method in a VB6 DLL containing the reporting business logic (generating a dynmic sql statement) VB6 DLL method returns xml data xml data are displayed with xsd transformation 150.000 datarows are displayed in some seconds (less than 10 seconds maybe) Now we want to extend this reporting function and decided to use asp.net (2.0) So I have written a little prototyp application with a SqlDataSource Object and a GridView Control.
A table with less data (about 100 or so) are displayed quickly.
But a view with about 150.000 datarows needs about 2 minutes and ended with a OutOfMemoryException!
The request of the customer is definitvely to display the data on one page like in the old classic asp application!

I have a datalist inside 1 datalist.In the first datalist i am binding the "advertisement posted" date field from sql server. In the second datalist i am binding the ads posted on that date using an object datasource. my pro is, i need to show a total of 100 ads in one page. This should not depend on the date. Total 100 postings in the page. For example
Todays date (02/25/2010)
50 postings
yesterdays date (02/24/2010)
if 75 postings are there,
50 postings
it should display only 50 postings under yesterday's date remaining 25 postings should display in next page(paging) with the format like this
yesterdays date (02/24/2010)
remaining 25 postings
(02/23/2010)
75 postings
how can i do the paging like this?

I'm trying to extend the GridView control to enable sorting and paging for any situation.
When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?
To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.
Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.
My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.
The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,
[Code]....
I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.

Background of what I have implmented so far:
I've used datagrid view to show a list on records on page, the list contains huge number of records so paging was required. Since the amount of data was huge it was not advisable to bind the grid with complete data. So, I used custom paging and tweaked the sql statements to get page wise data. Now whenever user clicks next or previous data for current page is fetched from the database and gridview is binded with that much data only.
Now I had to add a checkbox column to the grid so that user can select multiple items on multiple pages and perform an operation (for example send email to selected people in the list). I achieved this by making a template column with checkbox control and keeping a boolean column in the datatable which is binded to the gridview. I've also kept a collection selected checboxes so that the state is maintained on every postback.
I've also used ajax so that user cannot see postback happeneing. Everything works just perfect.Here comes the problem:
Now say I have 5 pages of data to be displayed. I select 3 people from first page and move to next page, this will cause fresh databinding and previous data will be lost.Now I go on and select 3 more people from page 2Finally press the send mail button What is expected here is that the mail should be sent to 6 people but details of only 3 people are available because grid is rebinded.
What is the best way to cach data of selected rows in this case. The number of columns is around 20 out of which I show only 10 columns on screen and others are kept hidden. The values of hidden columns are used while sending the emails.

We have a page the we have to write where users are shown 'pages' of data from our database they then select the row they want and we take them into another part of the application where they can work with the data.
When we use the built in paging (in the gridview) it is just too slow, as there is too much data.
We have written paging into our stored procedure that gets the data to work around this. The stored procedure works just fine and it is quite fast.
How can I get 'paging' buttons into my gridview when I am not using the built in gridview paging?I can keep it simple if I have to (next and previous only) but it would be better to have a 'first', 'previous', 'next', 'last' type buttons.
I cannot seem to figure out how to get these buttons into the gridview however.
some sample code (preferably vb) that would show this? (or something similar)
Built in paging is not an option.
