How To Gridview Sorting - Column Data Vanishes
Aug 18, 2010
I 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.

In gridview columns im displaying date and time, as below.
23/02/2010 11:19:52
Im also doing sorting on these columns.
But the issue is during sorting its only sorting on "day (dd)"....
for example....these 3 values are from column, Date.
23/02/2010 11:19:52
18/02/2010 10:25:10
17/03/2010 09:30:51
when I click for "Ascending" sort....it should get "17/03/2010 09:30:51" on the top (because of month 03) others have 02, but it doesnt, it gets in the above order, its just sort on day (dd).Below is my code for boundfield....
<asp:BoundField
DataField="Date"
HeaderText="Date" [code]...

I have a gridview control bound to a sqldatasource in c#. In the rowdatabound event I look at a value in a cell and use a function to evaluate the value and depending on that value I populate an added unbound column in my bound datagrid to show an excalmation point. I now want to sort by the column with the excalmation point.

I have a page that has a gridview which contains a loginview that contains hyperlinks with different navigateurls based on the role a user is in. When then page first loads everything displays correctly. However, if there is more that one page of data and the users clicks on a subsequent page, the column with the hyperlinks is blank (the anchor tag gets written out but no href and text) all of the other columns display correctly. If you click the back to page 1 the hyperlink is blank. The only way to get the data to redisplay is to reload the page.
Is this a proper use of the loginview control?

(Example code below)
I have a GridView. It has a 'static' TemplateField (in the .aspx page). I add and remove BoundFields to it depending on user preferences on postback. Affter the second postback, the template field appears empty.
Here is a stripped down mockup of what I'm doing. You can click the "Regular Postback" button as much as you want, and nothing bad happens. But if you click the "Recreate" button once-- it's all ok. Click it again, and the "one" column goes on Christmas break.
So is there something else I should be doing, or is this going to be a "halcyon1234 to code interface" error.

Situation: SQL database, Linq to SQL class a ASP.NET page with a LinqDataSource and a gridview. The table has a ID field, a date field and a Serialnr field. In my Grid I like to Page on the datefield but to sort on the serialnr field ( or a selectable other field). Is that possible? Standard the paging is always done on the sort field and when you select a different sort field the page jumps back to the first page., and paging is then done over that sorted column.

I am looking to sort a column on my gridview by simply clicking on the column rather than clicking on the column header. In the design I have been given, the column header will not be shown, and I need to be able to give the user to sort this column, by simply just clicking any where on the column.

i have a GridView bound to a DataView. Some columns in the DataView's table are foreignkeys to related tables(f.e. Customer). I want to enable sorting for these columns too, but all i can do is sorting the foreignkey(fiCustomer) and not the CustomerName.
I have tried this without success(" Cannot find column ERP_Customer.CustomerName "):
<asp:TemplateField HeaderText="Customer" SortExpression="ERP_Customer.CustomerName" >
A tried also the DataViewManager, but i've a problem to detect the table to sort:
[code].....
I have to apply the sort on a distinct table of the DataViewManager, but this table would differ on the related tables.
I have bound the TemplateColumns in Codebehind in RowDataBound-Event f.e.:
Dim LblCustomer As Label = DirectCast(e.Row.FindControl("LblCustomer"), Label)
LblCustomer.Text = drCharge.ERP_CustomerRow.CustomerName 'drCharge inherits DataRow
What is the recommended way to sort a GridView on columns related to other tables? I could build a custom datatable with the customername instead of the foreignkey and bind this column to the TemplateField. But then my huge dataset in the model makes no sense anymore.
EDIT: I have a model with a Dataset. I'm binding one Datatable(ERP_Charge) from it to my GridView(actually i take a Dataview from that Table). In this Datatable are columns that are related to other Datatables in the Dataset(relations are defined). When i want to make the grid sortable its no problem on the columns that belong to ERP_Charge.
But the columns with foreign keys to other table could not be sorted because the Gridview shows f.e. not the CustomerID but the Customername. I get the Customername in RowDataBound. Normally i would join the tables and add a Datacolumn for the Customername.

I have given an access to stored procedure, which i'm not able to edit. This Stored Procedure returns a Table with 2 Column, what I did is set a GridView's DataSource using SQLDataSource in this stored procedure. but I want this GridView to Sort an specific column to descending whenever this GridView Loads.
<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource2" ForeColor="Black"
Width="58%" Height="125px" AllowPaging="True" AllowSorting="True"
PageSize="5" >
<Columns>
<asp:BoundField DataField="DateOccur" HeaderText="Login Date"
SortExpression="DateOccur" />
<asp:BoundField DataField="TotalMinutesPlayed" HeaderText="Total Minutes"
SortExpression="TotalMinutesPlayed" />
</Columns>
<AlternatingRowStyle BackColor="#EFEFEF" />
</asp:GridView>

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 have a Gridview with a templated column which contains just a label.
I set the Label1.text during GridView1.RowDataBound based on doing a DataBinder.Eval(e.Row.DataItem,"myColumn") and a calculation off that.
When the user clicks the header I want it to sort based on what's in the Label but instead if seems to be sorting on the contents it was bound to, "myColumn", even though that's not what appears in the grid.

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 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
