Am trying to use sorting and paging using a Asp.net DataList Control.....I found a Tutorial at asp.net website, but not able to understand that. I found other two links ,which exactly is of my need...but the only thing is that , it is in VB...[URL]
But Am working with C# I wanna Use Sorting & Paging For this

Moderators Note: THIS ISSUE IS BIG FOR ME AND EVEN IF POSSIBLE, GET THE REPLY FROM THE DESIGNER OF GRIDVIEW. I have been looking for him for long. I am really fed up with reviewing a good lot of web pages on how we can possibly customize the gridview to enable sorting and paging. So many sites have listed out a lot of information and so many guidances. But the problem is that one works out fine and the other is a burden. I really feel bad about being given the job of customizing this kind of a gridview which has no user friendly approach to it. Also, this control is rendered without the pager links inside the <tfoot> tag. I have tried the Pear Pager in php. It is that good and easy to use and compared to that, the gridview in asp.net is the worst ever control i have ever tried so far.
1. i can use the images to indicate the sorting direction
2. I can have the custom pager like
[code]
<<Previous 1 2 3 .. 7 Next >>.
[/code]
When i click the next when i am viewing the page at 3 , the pager links should change as
[code]
<<Previous 2 3 4 .. 7 Next >>
[/code]
Kindly look into this type of requirement and firstly tell me whether this is possible with the gridview control. I would like this request even to be escalated to the designers of the gridview control also, so that Microsoft comes out with a reply THAT WORKS and not the kind of stuff like surfing through a lot of links and pages and finally wasting a lot of days precious time and still breaking the head with this useless control. I have spent a lot of time in searching for a perfect way. Not writing a code that is non-standard. I am really serious b'cos I have spent weeks in customizing this control. If I dont get a solid reply atleast now, I am going to generate all the output by HTML content by custom coding.

View 1 RepliesI'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.
How can I do paging with datalist if that datalist is populated with inputs coming from a querystring?

View 1 Replieswhat I am trying to do;I want it so that when the user clicks on the datagrid column headers to sort the records, or when they go to page the datagrid, that a confirmation pop-up appears first, confirming that their changes are going to be lost (unless they click "Cancel").I have the confirmation pop-up scripted in Javascript and is added to the controls on the page using
[Code]....
How do I attach this to a datagrid header and to the pager?Do the columns need to be Template columns and the header text being hyperlink? If so, how do I set it up so it will, if the user clicks "OK" in the confirmation pop-up, still sort?
I am binding DataView data to GridView and using paging and sorting mechanism of the GridView.
In case of sorting, I define the sort expression based on user's selection and assign the same to DataView and then bind the same to GridView.
Issue:
Everytime I sort the DataView, I see different set of rows on the same page on GridView. The issue is, the column which is used in sorting has many rows with same values. So everytime I sort DataView using sort expression and bind it to GridView, it displays different sets of rows and sorts randomly.
What should I do to make sure that it always display same rows? I cant change the sorting expression as it is selected by the user. Or only way is to append sort expression containing unique key internally ?
I need the consistent set of rows as I am operating on rows selected by users and make them editable and allow user to udate values and display the same.

I have a problem with the allow paging and sorting in the gridview. I have a button to export the gridview data to excel and I need to disable the paging and sorting in code behind. When I export to excel it have the link numbers of the paging and the column header as a link to sorting. I'm using VB.
[Code]....
I don't get the paging and sorting disable.
I modified my gridview to include paging and it messed up my sorting.See a sample code below and it is not working unfortunately

I've reviewed a couple other sources and none seem to be complete, there is always a 'oh, ya, but you have to do this if you have this, or comments left about it not working etc... So this is my attempt to get a complete answer in one place. No datasourceControl, datasource being assigned programatically upon a button click event. My button click event that originally binds data to the gridview looks like this:
[Code]....
and of course the first code I try to implement the paging, doesn't work. Which is this:
[Code]....
the result is not an error, just an empty gridview. What am I missing? That's just an example of most of the examples out there saying how simple it is and you only need a few lines of code being wrong, or maybe not wrong, but incomplete. So I'm not going to even bother with the bidirectional sorting examples I came accross as there are usually comments about it not working, or not actually being bidirectional. I'm sure it is simple, once you actually have the information you need, getting that information is the harder part. So, anyone here care to take a shot at a complete example of implementing paging and bidirectional sorting on a gridview when not using a datasourceControl?
