Forms Data Controls :: Dynamically Sort GridView On PageLoad?
Jun 29, 2010
I'm making a call to a web service which returns some data I want to disply in a gridview.The data returned contains two columns "UseDate" & "Quantity" I need to sort the grid by UseDate on pageLoad...I can only make a call once every 120 seconds to return the data.
How can I get the GridView to sort?I have tried couple things but either it does nothing or I get an error... that the Grid fired an unhandled event.
[Code]...

Just spent about 8 hours googling and looking through this forum for a solution on how to make sure that I can dynamically sort. Here is the situation.
I have 1 Gridview that displays 10 different scenarios based on what button is clicked.
I am also returning only top 10 records. I am doing all of the data binding pragmatically. So I have BoundFields, HyperLinkFields etc.
I also want to sort some records. When I change DataSource SQL statement the gridview somehow remembers what the last sort value was and it errors out saying that value "x" cannot be sorted because it does not exists.
I tried this:
Tried setting gridview1.sqldatasourceid = null; gridview1.allowsorting = false; gridview1.databind();
Here I get an error that says that the data source does not support sorting? Doesnt it say gridview1.allowsorting = false;
I also tried gridview1.sort("", SortDirection.Ascending); This does nothin... except query my database one more time because i have a onSorting event that looks like this:

Here is an example of just one of those SLQ statements inside GetSQLQuery:

I have a gridview with data. I want a button which is not part of the gridview. Then if I press a button the gridview is sorted by two colums. i.e column1 ascending column2 descending.
I am not looking to work with a Sqldatasource as I use a data access layer. So the sort would have to be from a datatable and databind or directly with the gridview.

I'm a newbie to .NET, so the solution might be really trivial. I have a database, I have an Entity Data Model, I add in my Index.aspx page an EntitryDataSource and a GridView. I connect them and everything works fine (the data is displayed as expected). The problem is that clicking on the coulmn name or on the pagination lists doesnt do a thing... Although I did set the properties AllowSorting="True" and AllowPaging="True". I also tried with another datasource type (SqlDataSource) and the same problem.

I am using gridview created by visual components. I have registered gridview_onsortclick event during the page initialisation, but when i try to click on the header of any column, this event does not get fired at that time. This event gets fired only after all the controls, sorting query is generated, filling the current dataset is done. But the same event is getting fired before query is generated and dataset is filled,for the other page. And one more thing to add with it, I want the sort function to be done on the whole dataset regardless of current page. Why is there such a difference in both the pages?

I have a gridview column named "Job Number" and the number is in this format: 01-04-11-3215, 01-04-11-3216 and so on...
Since the first few characters represent the date I need to sort on the last 4 digits.

Tried several different ways to do this but am just not seeing it. Proably a quick solution for someone more skilled than me.
I have a gridview generated from a datatable. One of the columns is "client name" whose data is generated from a class.
I added a link button for the column header that fires a sub that should sort the datagrid, but is not.
Here is the code I have so far that creates the gridview which works fine:
Private Sub PopulateCaseListGrid()
'Kill the existing DataSource, in case of a page reload
gvCaseList.DataSource = Nothing
'Create a datatable with whatever column you want to use

I have a GridView and Formview attached to the same ObjectDataSource.
Everything is working ok so far.
If I enter new search criteria and click "Search", both the GridView and FormView rebind properly to the ObjectDataSource results. And I am able to page through the FormView records and they match the GridView records above.
When I click a sort link in the GridView, the ObjectDataSource returns the correct results based on the header link's commandName of 'Sort' and the CommandArg of 'SortExpression'.
The only thing wrong now is on the sort, the formview records do not reflect the reversing of the sorted record order. If I page through the FormView the records remain in the same order.
Why does the FormView not recognize the ObjectDataSource's changed results on the sort post back (even if it is only the sortExpression parameter of my ODS select method).
How do I get the FormView to rebind to the new ODS result set? I have called formview.DataBind() from every event I can think of. That does not seem to work either.

I use Server.Transfer("pagename", True) to navigate from a page where two dates have been selected to a page with a gridview that uses the dates to query the database and display the results. The gridview initially displays correctly but when I operate the select or sort it disappears.
