Forms Data Controls :: Access The Instance Returned By Details Page?
Jan 28, 2010
I have this specific task: I have a contacts table, and when users view a specific contact in details page I want to display a button in the page (doesn't matter anywhere, but inside the detailsview control next to the "edit" hyperlink is better), when it's clicked I want to grab all the info of this contact instance and write it to Response so user can save it through the save file dialog. So far I have two problems1. How do I access the contact? it's displaying on the page but when I tried detailsview.dataitem it returns null, e.result in the datasource selected event handler also returns null...2. I can get the button (outside the detailsview control) to trigger the file download dialog, but how do I achieve the same thing if the button is placed inside the details view which is in turn inside a updatepanel?
I am having some difficulties with a particular task. I am creating a support desk intranet application and I am trying to write a method within a class within a namespace which will form a generic database connection which can be called from any of the aspx pages so that I have the dbconnection logic in one place; you know, going along with the 'DRY' (Don't Repeat Yourself) mantra.
The Namespace:
SUPPORTDESK.SQL.dbconnection.pullData()
Objective of the method:
To provide any aspx code behind file with an SQL Server 2005 Express Connection and if possible return the data from an SQL Query. This is where I need advice do I create the method such that it simply forms the connection and returns a DataSet or that it returns an SQLConnection object? If i've got things back to front and upside down don't worry I'm a beginner with ASP.NET. The Method so far:
[Code]....
If I'm on the right track how do I access the data returned in the DataSet?
I am trying to use a DetailsView to enter a new row into my database, but need to enter a further row in a linked table at the same time.
I am able to use the "iteminserted" event to gain control after the event has completed, but I need the key to the row i just inserted into the main table.
I am using a dataset, so the insert is managed by a tableadapter which has been configured to return an integer with the newly created identity of the row i just inserted.
Does anyone know how I can get access to that identity? is it in the "e" object of iteminserted? how do i find that if it is?
Here is the VB CodeBehind I am using to insert the row in the linked table (the DetailsView has just inserted a row into the "Books" table and the database has just assigned it an identity which should have been returned to somewhere by the tableadapter. I need that identity as a key to the "BookAuthors" table):
[Code]....
This is the ASP code for the DetailsView and the DataSource:

And here is the code for the tableadapter i am using
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 have a gridview control with a details column. I want the user to click details and it give me a pop-up showing details of the particular row. Any idea on how to do this using JQuery?? Looking for an example with code..
I have a details view that appears when record is selected in a GridView. Can this details view be opened in it's own modal window that would allow me to use the full event model?
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:
My goal is to load a row details from db to a webform and let the user update it's value .
The user searches an id (i have a stored procedure for that), how i show that data from the row nicely in the web page through the dal layer. After the data is shown on the page the user need to update a cell in the row and send it.(the part of updating is not the problem).
in other questions how should the dal method should look and how i integrate it's result in the presentation layer (the aspx webform).
I have a listview using Update to edit records. Something is wrong with the SQL update command. I get an error on page "Input string was not in correct format". How can I view the actual SQL statement being generated?
There seem to be a few issues in the way Razor views are designed and the code generated
1. Descendants of WebViewPage are forced to override Execute() (since it is abstract) but that method is never called. Why? 2. The virtual method ConfigurePage is never called in descendants that override this method. 3. CreatePageFromVirtualPath is no longer virtual. This was the one method that gave us access to the Layout Page (Master Page) instance. Now we no longer have this access. Why was this done?
How can one get access to the instance of a Layout page?
However, the details page could not retrieve the page base on the clsNotesID. Here is my SqlDataSource control:
[Code]....
The clsNoteID has a DataType of uniqueidentifier. I was wondering if the clsNoteID passing through the QueryingString has to be suround by a single quotes. If so, how do implement the single into my HyperLink control?
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
Site basically has datbase results which can be sorted on a page. each record in the recordset also has a link to a Detail Page with more information on that item.
I would like to put some links "previous" and "next" on the details page so that a visitor does not have to go back to the results page and choose the next item in the list.
I've seen this on other sites but just can't seem to grasp it. Database results are done using ASP.NET
Anyone have any pointers? or if you have an asking price I'm all for that as well as long as I learn from it. I can provide url and code if needed.
i am using a usercontrol with repeater for custom paging in grdiview. Everything works fine. I am able to display link buttons and able to pull exact records. Now i have a little user friendly requirement. The pager usercontrol should appear at top of grid and bottom of grid. For that i have placed two instances of usercontrol. I am supposed to place same instance of usercontrol in two places so that whatever button click in any instance should happen in all available instances. The issue is i clicked page 2 (link button) in top pager user control. Its changed to selected mode(non clickable) where as bottom remains same, page 2 is clickable. How can i proceed?
I have requirement like to display the Master details records in the page, without clicking the parent record (for getting ID to retrieve the detail record) i need to display all the child records in between the Master records while page loads.
I have records in a Gridview, when I click on the NAME of each item I want to open up and new page and display a more detailed view of the record, i.e. the extra details from the table. I have the following code setup:
I have two tables: Book and author and they have one to many relation.One book may have more than one authors. Book table has Title column and Author table has AuthorName Column.
I have search page contains two textboxes: Title Textbox and AuthorName textbox to search the record.
When the user type something and hit the search button it display the Title when click the title ; it redirect to detailsPage.aspx Passing value ID.
[Code]....
Then in the Details page there are: Title, authors and other more from these table column.
My problem is:
When the user search and hit the search button, it display the number of matches Title only. I want to display authors related to this title in this page and other are same(when click the title go to detailspage.aspx)
How can I display the related Authors to each title in search display page (Not in details page, I know in details page) ?
If user search "The Letters and life" in the Title textbox and hit enter data should looks like:
1. Author: Payne Paddy, sed ran, der virma and Caroline Barron.
Title: The Letters and Life of Elizabeth Despenser, Lady Zouche (d. 1408) [her letters and will provide a glimpse of her personal
I have a GridView which is linked to the database via SqlDataSource.
What I would like to do is to make each row of a designated column clickable. Once the user has clicked on a row, the application should postback to another page to allow the user to read all the details of that row.
The effect should be as we can see in this post: if you go to "mypost", you have a list of posts and then when you click on one of them you are able to see the details of that.
I read lots of posts that are using, however, other methods such as datalist + dataset controls etc.
I'm writing new section to a website and am looking to use a UI similar to the MSDN Download page with the Product Details and Keys in an accordian like section. Haven't been able to find a description of how this is done as of yet - still looking though but figured I'd ask if there is an available control or a description of that control instead of reinventing it.
