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.
I got a web page, it has a tabcontainer, within each tab, there will be a gridview, all the tabs and gridview are created at run-time, i have only one code, that I will loop through to create all those tabs and gridview. When I apply the sorting, and I click on the column name on any grid, it returned an error saying index was out of bound. BUT, when there is only ONE grid view created, it is working fine, I suspect it mixed up all the grid view's id and so on. But I have assigned different ID to gridview

that aspx page contains gridview that contain one more gridview inside in it.Now i want to sort out both the grid i.e)claimgrid and Gdclmline1 i want code in c#.
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.
how I do a sorting in a gridView with data bound by a ObjectDataSource?
View 2 RepliesI have a Gridview, which I bind to a Dataview programtically. My Gridview has 11 columns. Sorting works fine as long as I do not remove any columns programtically.
In certain cases I remove 2 of the columns from the Gridview. Still not a problem. All the data is properly displayed however the problem occurs when I sort one of the columns. I sort the Dataview and bind to the Gridview again. Data from two of my columns just vanishes. Both of these columns are based on ItemTemplates. The columns are still displayed but just empty cells.
I am using Object Data Source to bind data in the gridview. I haveset the property AllowSorting=true. While running the application, Icould sort the data only in ascending order. Is there any way toachieve two way sorting in gridview ie. both ascending and descendingon successive clicks ?.

I'm trying to sort GridView but I have problem with converting DataSource to DataTable. Object of DataTable is empty. I don't know how to convert it.Do you have any ideas? Here is my code:
private void SortGridView(string sortExpression, string direction)
{
DataTable dt = GridViewDzialania.DataSource as DataTable;
DataView dv = new DataView(dt);
dv.Sort = sortExpression + direction;
GridViewDzialania.DataSource = dv;
GridViewDzialania.DataBind();
}

View 2 RepliesI set Allowsorting="true" but sorting is not working in my GridView.Here is code of aspx page:
[Code]...
I have a single gridview and multple objectDataSources. Based on the user's input I bind the correct objectDataSource to the gridview in the OnClick handler when they click 'search'. ThegridView/ObjectDataSource have customPaging enabled and all that works, but I can't get the sorting to work. The sorting works when I have 1 ODS dedicated to 1 GV, but since it is set on the fly, no dice. It complains that I need to have a 'GridView1_Sorting' event. I think the answer lies in some how sorting the data inside of the ODS programmatically, but I don't know.

View 7 RepliesI 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.

How can I enable automatic sorting of my BLL which returns a list, CustomerList:List in a GridView? Customer is my own strongly typed class and CustomerList is a List of customers.I know one approach is to set the AllowSorting property to true in the GridView and handle the OnSorting event and calling a sorting method defined in my CustomerList class.
However I would like a solution which is automatic in the sense that I do not have to handle the OnSorting Event, it should be like how GridView handles automatic sorting for DataView, DataTable, and DataSet.Is there an Interface I need to implement on my CustomerList or Customer class that will enable that functionality?
I have a gridview that can be sorted by a few of the columns.
How do I tell the gridview to go back to the unsorted mode. That is, go back to listing rows in the order they appear in the datasource.
It's ok if this will only work the next time a rebind is done on the grid. Currently it's maintaining the sort mode after a rebind. I don't want it to do that.
