Sorting GridView By Row Number In C# ?
Sep 18, 2010
I have a GridView with a row number (Container.DataItemIndex) column in ASP.NET (1,2,3,4, ...)
I added it in GridView by following code :
<asp:TemplateField HeaderText="#" SortExpression="#">
<ItemTemplate>
<%# Container.DataItemIndex + 1 %>
</ItemTemplate>
</asp:TemplateField>
I wanna sort the GridView by this column. I mean
ASC : 1,2,3,4, ...
DESC : n,n-1, ... , 4,3,2,1
How can I do it ?
Edit: I did it by this way [URL] but it sorts # column like 1,11,12,13,...,2,21,22,...
I want to sort # column 1,2,3,...,11,12,13,...

im not sure why but my gridview seems to have stopped working in all areas of Editing, Deleting, Sortinging and i cant click the page number to switch between pages.Ive looked up numerous tutorials and on forums and still cant seem to find a solution that works for me. I have the edit delete sorting and paging check boxes selected.
When i click on any of the links nothing happens. not even a refresh.
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="NumofPosts"
DataSourceID="SqlDataSource1" [code]......

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

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 have a web application (with C#). I have a GridView and want to be able to sort its contents. I have added the tags
AllowSorting="True"
onsorting="MyGridView_Sorting">
asp:BoundField DataField="NAME" HeaderText="Name" SortExpression="NAME"
inside the GridView. I have implemented the MyGridView_Sorting method. Thing is: it does not work. Does nothing. The header text "Name" looks like an active link, but clicking produces no effect. Putting a break point inside MyGridView_Sorting shows that it actually never goes inside the function. What is wrong? What do I miss?

When "AllowSorting" is true on an asp.net GridView, it just makes the headers with a SortExpression clickable. Trouble is that it does this with JavaScript links - so with JS turned off you cannot sort the columns. Before I go and write my own HeaderTemplate to use Querystrings instead of JavaScript, am I missing an easier way of being able to sort a GridView without any relyance upon JavaScript?

I have done research on how to manually create sorting in a grid-view and none of it is thorough enough for me to follow. I need more of a step by step solution, like what event should my sorting code go in, how would i enable the headers to allow sorting. normally, i just have .net do this but for some reason this time it doesn't allow it, maybe because i am not using a datasource.
that's my code that creates a datable and then binds to the gridview.
Function toptable()
Dim reader As SqlDataReader
cmd.Parameters.AddWithValue("@yeartoget", DropDownList1.SelectedValue)
cmd.Parameters.AddWithValue("@mode", RadioButtonList1.SelectedValue)

I have a method
[code]....
and it's starting to smell, bad. I have 4 columns that I have to sort on. I'd like to avoid doing a switch or something to determine which property on the CustomerSet I'm trying to order. What would a better programmer do to associate the SortExpression, which is a string, to the property on one of my CustomerSet objects?

I have a grid bound to a linqed SP thus:
Session["results"] = db.spGetCaseByNumberOrSurname(txtCaseNum.Text.Trim(), null).ToList();
gvResults.DataSource = Session["results"];
on the sorting of it, i would like to be able to do this..
protected void gvResults_Sorting(object sender, GridViewSortEventArgs e)
{
string sortExpression = e.SortExpression;
List<spGetCaseByNumberOrSurnameResult> data = Session["results"] as List<spGetCaseByNumberOrSurnameResult>;
if (sd == SortDirection.Ascending)
{
sd = SortDirection.Descending;
gvResults.DataSource = data.OrderBy(d => d.GetType().GetProperty(sortExpression));
}
else
{
sd = SortDirection.Ascending;
gvResults.DataSource = data.OrderByDescending(d => d.GetType().GetProperty(sortExpression));
}
gvResults.DataBind();
}
sadly that doesnt do any sorting at all..it in fact errors with "The data source does not support server-side data paging."
