How to implement sorting in gridview with datasource present as viewstate since paging is required,and with columns conatining alphanumeric characters( sorting as like of windows explorer)
View 1 RepliesI have a gridview to which I am binding a database values. My requirement is to bind the values to the gridview by sorting 3 columns as a default sorting with ASC order in one column and descending order in other two.. Can I do it in my .Net code or should I do that in Stored Procedure? If it can be done in .net code Can you tel me how it can be done.

View 2 RepliesModerators 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.
can i implement multiple column sorting in an ASP.NET DataGrid.Datagrid contains Template columns.
View 5 Repliesi have a gridview populated by a Web Service search function. some of the columns in the grid are templatefields, because the values coming back from the search (in a datatable) are ids - i then use these ids to lookup the values when the rowdatabound event is triggered and populate a label or some such.
this means that my sorting function for these id/lookup columns sorts by the ids rather than the textual value that i have looked up and actually populated the grid with (although i do put the ids in the grids datakeys).
what i want to do is top be able to sort by the looked up textual value rather than the codes for these particular columns.what i was going to do to get around this was to when the datatable comes back from the search, adding more columns the textual values and doing all the looking up then, thus being able to sort directly from the manually added columns.
is there another way to do this? as that approach seems like a bit of a bodge. although i guess it does remove having to do the looking up in the rowdatabound event....
my sorting function works by sticking the datatable in the session and on each bind grabbing the sort column and binding the gridview to a DataView with the sort attribute set to the column - and the direction.
I have a datagrid with two columns ( File Name, and Date Created ). I want them to be sorted when clicked (ASC or DESC). I went into the design view and added the allow sorting feature and added the column names, so they are clickable in the header of the data grid. I also already added the onsortcommand as well.
My datagrid is named dgFileList and the onsortcommand method is named dgFileList_SortCommand.
The procedure that is already loading on page load is a DataSet. (where I think my problem is)I dont have anything in the back end beside the dgFileList_Sortcommand method. From what I have read, it seems like I can't use a DataSet to be sorted...I'm using visual studios 2005, C#, not VB.
I have created gridview with list daatsource. I want apply sorting event for gridview to sort all columns.Here is my code:
protected void grduAdminSerservice_Sorting(object sender, GridViewSortEventArgs e)
{
DataTable tbl = grduAdminSerservice.DataSource as DataTable;
[code]...

View 1 RepliesI've been asked to take over a project that's filled with a bunch of bugs. It's currently using MVC 1.0 and there's a view with Html Helper Data Grid that uses a DataGridHelper class. I'm not that familiar with all of MVC yet, and I was wondering if it is possible to have the sorting of the columns be a POST event rather than a GET.
Currently when a user clicks a column to sort, the controller for the view calls the GET action method. This I guess is all fine and good, but the problem is that this view has a search form (which is a model in it's own right) with some text boxes and some drop down lists. When the GET action method is called, I lose all of the information in the search criteria. So when ever someone searches for something, but then wants to sort the results, it requries the db for all records (because all of the search criteria is cleared).
I guess there could be two solutions:
1) Is there a way to access the items in the search form / model in the GET portion of the action method? I've tried using ViewData or adding a parameter for the search form model, but (and maybe I'm doing it wrong) both return null.
2) Is there a way to make the sorting event of a column call the POST portion of the action method? That way I'll have the search form / model information and be able to sort the search result content instead of query for all records.
Also, there is a stored procedure that currently can handel all of possible search parameters. So, no matter what sort column is selected, or search parameters are entered, it can properly setup the sql query.
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.

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();
}
i have a grid view can any one tell how to apply sorting in it
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.
