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.

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 just want to slice paging every 5 pages because there are too many pages that's why the paging of the bottom looks too crowded.

var productList = (from p in db.KATEGORI_03s

I have a section on my website where I plan to add a lot of text-based content, and rather than display this all at once it would be nice if I could add paging on just these pages. If possible, I would like to put all of my content within one content item and have the paging work automatically, building a URL along the lines of http://example.org/articles/title?page=2 or similar.
I've stumbled across an article that mentions paging with Sitecore items and this seems rather close to what I require, although mine requires pagination on a single content item, rather than multiple items.
Is it possible to do this with a Sitecore content item?

I am trying to add paging to my datagrid. This datagrid stores hierarchical data. So the top row has several children rows that need to go beneath it. When a new top row type is going to be added I want to make a new page. This way all related rows will be displayed on the same page. So, I think the tricky part might be making pages with varying sizes. I am not sure how to go about attacking this issue. All of the custom paging examples I have seen still have x amount of rows per page. Like I said my pages have to all be various sizes.

In my asp.net Page I am using gridview. I am binding the gridview on page load and on paging event with one method. suppose as Bindgridview1();.
There is one search button for searching the records of user with different method suppose as Bindgridview2(); .
when I am searching the records with Bindgridview2(); paging doesn't work and directly bind with Bindgridview1(); which is on page load when I clicked next page.

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.

I hoping someone could answer a question for me. I am relatively new to developing web applications with .NET and I have question I can't seem to find a straight answer to. When allowing paging of a GridView control, how does retrieve the data per-page? Is all the data stored into an object, and then displayed x amount of rows at a time? Or, when moving from page to page, is it executing each time but restraining the result to the specified amount of rows?

I'd like to implement a custom paging template for my formview that displays numeric paging as well as next/previous buttons. The pre-defined templates only appear to have numeric first last as an option. Can anyone recommend a good article that covers this?

I am using dropdownlist to select whether the gridview should be filled by data arranged in ascending order or descending order with Gridview Paging. The problem i am encountering is that when i fill the data in ascending order it works fine but when i arrange the data in descending order the first page loads fine but the other pages are not filled properly in paging.

I have a gridview in a user control which I'm using to display a list of items. The data source is a list of objects (not using ObjectDataSource). I have paging enabled on my gridView. The trouble is that I am forced to rebind my grid in my paging method, otherwise the grid loses all it's data when a user clicks a page button. Is there a good way of binding to an enumerable list such that the values are reused on postback?
[Code]....
protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
BindGrid(); //Not Good. Removing gives me an empty grid.
((GridView)sender).PageIndex = e.NewPageIndex;

I'm having a bit of trouble with Paging within a GridView grid I have set up. I have added the paging but whenever I click on the next page or the last page buttons, the page refreshes and displays blank (i.e. no gridview but my regular search parameters are displayed.
I was trying to search for a solution throughout the web and came across someone that looked to have the same issue. He moved all of his queries into the Page Load method, and the paging seemed to work. I cannot do this because I have 2 different buttons: Search and My Order, both of which perform different queries based on if a date has been selected or what the search is on (Order Number, License Number, Description, Status, etc).
My paging method looks as follows:

From what I can tell this is an issue with no longer having the data set when making the paging call. Is there anythign that I can do?
