I have one page (Products) that searches for products which are then displayed in a gridview. Lovely stuff.
I then have a second page that is essentially a feedback form (Feedback). So therefore, a person should be able to search for a product, see its details in a gridview and then click on a hyperlink taking it to the feedback page. Upon arriving at the Feedback page, the product they were previously looking at (the gridview as it was) should be visible.
What I would like to do is transfer the gridview 'as is' (i.e. on what the person has searched for) to the second feedback page.
How would I go about achieving this?
Alternatively, if you could think of a better method for achieving the same effect (i.e. producing a feedback scenario), I am open to ideas. I could offer the feedback in the same page but I don't think it would be aesthetically pleasing with the page layout.
Please note, I appreciate that I could add an 'edit' element to the gridview itself but this is not approriate in this current scenario.
The simplest way to do this would be to make the original form and the feedback form the same ASPX page. You would simply hide or show elements, as you wish (using the Visible property). The grid view data would be persisted via ViewData.

I have a WPF Application with different user controls. Each of them can be accessed by clicking a button on the left side. My issue is, when I am in one of the user controls and filling out the data in textboxes, combo boxes etc, I may have to stop it mid way and click on another user control. While doing that, I need to keep the data in the previous user control intact so that when I return to the first user control, the data should be present in all the controls before I left it. How do I achieve this? Here's a sample picture of how my application looks like:

From the picture, if I am in the Products Page, I might have several text boxes with data entered in there. For a variety of reasons, I may have to step away from this and click on Home Page or some other page , do some work there and return back to the Products page. When I return, I need the data to be present as is when I left it.
Thanks in Advance
You must have create a ViewModel to each diferent user control.
ViewModel remains in memory until you process that or make a diferent process.
For Example you hava a User control for your Main Page, that's mean you have a view (MainPageView) of your user control for your main page, that view belong to a ViewModelMainPage.
For Products you maybe have a ProductView, that's belong to ViewModelProducts.
You must create a ManagerViewModel to manage the view for diferents user control.
I am trying to show the sum of totals for different kind of invoices on a web page.
I am using detailsview control, however it does not show all the data in one page. When I enable paging the other types of invoices can be seen on 2nd and 3rd pages.
My SQL command is:
SELECT CARI_HESAP_KODU, FATURA_TURU, SUM(KDV_MATRAHI) AS TUTAR FROM LNX_STD_6_016_01_SLSINVOICES WHERE CARI_HESAP_KODU=#mKodu GROUP BY FATURA_TURU, CARI_HESAP_KODU
When I run it from SQL I get the proper results:
But when I run the page and test detailsview I get:
So I have two questions:
1. Is it possible to show the results as columns (as in SQL view) instead of rows?
2. Is it possible to show all the records in one page?
Thanks in advance.
As stated in the comments by Esko, the details view only shows one record at a time. The details and Grid views are fast easy ways to display data, however if you wanted to customize how data is displayed, a more generic repeater would be the next logical choice, you would just have to do the formatting yourself.
Check out his article or google "asp.net repeater":
https://msdn.microsoft.com/en-us/library/zzx23804(v=vs.85).aspx
When I used to program in web forms a lot, I used repeaters even when a details or grid view would have done the job, because they are much more flexible and easier to maintain when someone asks for changes.

Using a combination of asp.net, jQuery, and c# and stored procedures.
I have successfully created a gridview, which I then apply jQuery datatables plugin to provide text column filtering (I disabled most of the other datatables function/settings off)).
The Gridview works as expected and when I make use of the RowEditing and RowUpdating events also, IE the editable fields update nicely.
If the user clicks and edits, then clicks the update link, the database is updated and the page reloads. now if that person has scrolled down say record 50 (half way down for instance) in order to locate and then edit that record, then after the page refresh, the user then has to scroll back down to find that same record.
I'm trying to find a way of returning the user to the same location (record) that they had just edited before the page refresh after the page refresh.
I found a very simple solution to my problem with out a load of coding and it turned out to be MaintainScrollPositionOnPostback="True" page directive.
Unless I've misunderstood; your dilemma is nothing to do with gridviews etc, and is all to do with merely maintaining page scroll position on post-back... have a read of this JavaScript solution from the 4 guys
P.S. Google is your friend
I have an ASP.NET page where at the top of the page is a search box. There are 2 text boxes - one is an autocomplete extender for the Name on a database, and one is just inputting the ID.
The page features DetailsViews and GridViews primarily, and even when no account has been searched for, these display blank data which is not ideal. I sort of fixed this by using if (IsPostBack), encasing the elements in a placeholder and setting it to visible only if the page ispostback. But this doesn't cover if the user types in an incorrect ID.
Also, some accounts have huge amounts of data inside the GridView's. I had an issue where because I have no way of detecting when a data source's rows has changed, I end up binding whenever the page loads (Page_Load method). I've come to realise this is simply very bad - there are lots of times when the user can click various things in the page and have the page postback, and it takes an eternity to load each time I click something for accounts with lots of data.
Anyway, my question is essentially two-fold but I have a feeling the solution will be similar:
1: How can I detect when there are no accounts returned when searching, and disable the Grids/Detailsviews and show an error message?
2: How can I figure out when the user searches for another account and only rebind the grids after that has happened?
Thanks
This method is very ugly but it'll get the work done.
1) To Check whether there are no records; after the AutoComplete Extenders Webservice is called if no record is returned put some value in Session like
Session["NoData"]=true;
if Records are found then;
Session["NoData"]=false;
after the webservice is called do ajax request to check that session & on the basis of value do what you want.
2) You can achieve this also by following the above option.
I'm working on a asp.net forms web application where I've got advanced search form with grid listing results below. Grid is sortable and pageable. Grid is listing products.
I've got two requirements :
1) make the url remember the advanced search form state so search results page can be bookmarked etc.
2) on the product details page there is a back button that should take the user to the advanced search page with the same settings in the form and same grid state.
I have implemented a workaround to above two problems but I don't think my solution is very clean and I'd like to hear better ideas. My workaround is as follows :
1) I iterate through form fields and I put values into the querystring after the hash. So when the page is loaded it gets the values from url if available.
2) when user clicks a link to product details page from the grid I use javascript to create a cookie with url to advanced search page so when rendering the product details page I know the url for the back button.
I'd like to achieve above functionality in cleaner way.
Thanks,
M
You could try setting the search page form action to GET. This will put everthing in the query string for you, enabling the bookmarking and the back button.
