Forms Data Controls :: Details View Edit Not Updating Record?
Apr 10, 2010
I'm new to asp.net 3.5 and I have been working through the tutorials using a real access database to learn how to use the new controls. I have an extremely simplistic page setup with a master-details view, the master using the gridview, and the detail using the detailsview controls. Everything seemingly functions correctly, except when I try to update the data in the details view. I make changes to the record, click update and the page posts back but nothing is updated in the database. No errors are given either.

I had another post about this issue, but decided to modify it to drill down and find the issue. I was doing a master/details, and that was not working, so I have changed it to just a single data source with a single details view created entirely via wizards. The issue is, when I click on the auto generated edit link, and change values in the fields, after clicking update the page refreshes without error but does not update the record. Here is the code:

I have a problem that is driving me insane. I have a simple detailsview that operates as you would expect a detailsview to do - the only difference being that in the updated event I send an email to various people to advise of detail changes (I have conditional testing to do this).
The problem is that if the user goes crazy with left clicking the update button, email recipients can receive multiple duplicate emails.
I have looked all over the net and seen many varied solutions for this problem - mainly using javascript - but none of them seem to be able to block multiple clicks without disabling or hiding the update button - which obviously causes issues with client side validation in the event that information is missing or incorrect.

I have created a Details View and set some of the fields to read only. I have added the edit command which is allowing me to edit all of the fields that are not set to read only but when I press the update button all the infomation stored in the readomly fields gets deleted and just show up as blank is there a way to stop them from getting deleted.

I have a Drop Down List, a GridView and a DetailsView. The Gridview is the master, the details is the records detail view. When we edit a record and click the update button, I want the page to refresh the gridview and detailsview. Right now after clicking the update, nothing happens, it just updates the current details record.

Hi. On my webpage, I have a listview that has a field called BookId. I also have a Detailsview with an ID field. When I add a new record on the listview, I would like to populate the BookID from the Id on my detailsview (there is a one to many relationship between the 2 ids).

This details view is part of a Master/Details. It appears in it's modal pop up like it should when a record is selected in the grid view. But then when the edit button is clicked in the details view the details view and modal pop up disappear. Everything else works correctly. I've used this same pattern successfully for other pages with out this issue.I don't understand why this is happening. There is no event handler that is tied to this. I don't have any code that would cause this.The edit button is just using the edit command that's set declaratively in the mark up. It doesn't have any code in the code behind that would override this.code for the details view:

I have a details view with buttons in the footer. When the user clicks the edit button the calls the ChangeEditMode() method. I want to change the mode of the details view to edit mode which seems to work fine. It goes into edit mode with a text box. I also want it to set the visible property of the edit button to false and set the visible property of the update button to true. Then while still in edit mode the user can click the update button that will call the appropriate method to persist the changes.
I got the changemode() to change to edit but can't change the visible property of the buttons correctly. This is what I have so far. Can some one please tell me what I'm doing wrong?

I'm very new on VWD, but I got the hang of it for the past 2 weeks(thank you for all the videos posted here in ASP.NET),but I'm really weak on the coding part(vb & c#),except for all the sample shown on the tutorials. Anyways, I have a simple project that
does insert, update & delete to SQL express using the details view. But to complete my project, I need to add a button that will create an event to restore the very last record inserted in SQL and display it back into the details view for minor modification
and nserted again as the newest record with the mod. I'm doing this so user, doesn't need to re-key-in redundant information, like names, original date & time etc, and just make modification on the description of the last record.....

I have a vb.net page that has a editable detailsview. When a user wants to erase the data for a field, they highlight the data, and delete/backspace over it, and click update. However, the original data is still saved. If they are replacing the current data with new data, that works fine and updates/saves correctly. This problem only happens when the current data needs to be removed.

I have on a page a gridview that can be filtered with one text box. I set up the gridview to show select and wanted to then connect a details view so that when you selected a row the entire details would show up. When I run it I get this error. Data keys must be specified on GridView 'GridView1' before the selected data keys can be retrieved. Use the DataKeyNames property to specify data keys.

I'm trying to get a record to show up in a details view as part of a Master Details. I was able to get this to work by setting the visibility to true for the Details View in the Page Load event. I now want the details view to show up when the Select button is clicked in the GridView's template field using the onClick event for the button. I don't seem to be assigning the correct properties to get this to work though. what property I should use with this? I know I have to get it from the GridView and assign it to the details but haven't gotten it to work. this is the GridView:

Over the last couple of weeks, i've been playing around with expression web to try and update our current company website: [URL]
Basically, our site is quite simple. We have individual product categories that are displayed and then the user can click through to view the individual product specification and pictures of said product.
I've created the category pages and inserted hyperlink fields to link to the individual product pages which works fine.
The problem i'm having is getting the specification and pictures to display on the product pages.
I'm literally tearing my hair out as i'm quite new to this.
The access database i'm using has the following fields, ProductID, CategoryID, Description, Comments (This is the Specification field) and then Image1, Image2, Image3 etc all the way up to image 10.
What i've been trying to do is to use an imagefield within a gridview to pull the Image name from the image fields and then display said images from the images folder. I have got this to work of a fashion, yet all the images are displaying instead of the particular product images only. I believe i need to add a query string to do this yet i'm totally at a loss as to how to set this up...
I'm also having the same problem with the specification (comments field) as i can't figure out how to only display the individual product spec..

I have a datalist which when a record is clicked you get taken to a details page .../details.aspx?ID=12And that record is displayed in a details view. All this works fine. My question is how can I add the next and previous buttons on the detailsview so they work? If the details view is on the same page as the datalist works no porblem but on a seperate page I get no next and previous records

This details view is in a modal pop up. When the edit button is clicked the details view should go into edit mode with the edit button being switched to not visible and the update button being set to visible. This worked with a non ajax Master/Details. Now though when the edit button is clicked the details view closes, or disappears. I don't have any code to set the visible property of the details view to false. I don't understand why it's disappearing and why the buttons aren't changing the way they should.I also tried this with the OnClick event but the same thing happens.
