I'm trying to add the code, programmatically, to ask the user if they want to delete a record that is being displayed in a DetailsView control. It is called Tutorial 22: Adding Client-Side Confirmation when Deleting by Scott Mitchell. how it could be done in a DetailsView. Here's some of the ASPX code:

And here's what I've got for my DetailsView1_DataBound() event code:

I have an .NET 4.0 / C# web application that contains pages with GridView controls on them. There is an Entity Data Model and EntityDataSource objects that allow for CRUD operations against the database. My questions are the following.
How can I setup the delete command in the GridView to delete recursively, given my setup? In otherwords, how do I cause it to delete the record selected as well as any records related to it, and any records related to those, and so on? Also, how do I incorporate verification of deletion before deleting? What I would ultimately like is a 3-button window to pop up. "Delete", "Delete Recursively" and "Cancel" would appear. I'm also open to other suggestions for a better way to do this.

I have a bound datagridview with the associated tableadapter, dataset and bindingsource. A different component in our application can add or delete rows displayed by the datagridview. When this happens, the underlying database edits are correct. The problem is that the datagridview seems to lose track of the data.
Currently, when we receive the event that our data has changed we do the following.
this.DataSet.Offers.Clear();
this.TableAdapter.Fill(this.DataSet.Offers);
this.BindingSource.ResetBindings(false);
this.DataGridView.Refresh();
If our example had something like 5 items displayed in the grid and a row was deleted, the grid refreshes with 3 items shown. If we manually refresh our grid through a button calling the exact same code, it displays the correct results. Is this an asynchronous call? Should we be refreshing the grid in a different area?

The following is a note from Professional ASP.NET MVC 2 by Scott Hanselman ++
You might ask — why did we go through the effort of creating a <form> within our Delete Confi rmation screen? Why not just use a standard hyperlink to link to an action method that does the actual delete operation? The reason is because we want to be careful to guard against Web-crawlers and search engines discovering our URLs and inadvertently causing data to be deleted when they follow the links. HTTP-GET-based URLs are considered safe for them to access/crawl, and they are supposed to not follow HTTP-POST ones. A good rule is to make sure that you always put destructive or data-modifying operations behind HTTP-POST requests.
If web-crawlers and search engine have no access to the page containing deletion button, is it safe to use a standard hyperlink to link to an action method doing the actual delete operation?

Whenever I write lines like this:
<%: Html.LabelFor(model => model.AccountName) %>
And save the file, some lines (some, not all of them, haven't figured out the logic behind this yet) will be converted to this:
<%: Html.LabelFor(model => model.AccountName)%>

I have an sql table in which i have two columns enq_no and enq_serial.
for a particular enq_no, enq_serial should get incremented by one starting from 1.
What is the best approach to achieve this?
another issue is that after deletion enq_serial should get decremented by one.
How can i get this?
Is after delete trigger could be a good option?
If so? how can i get this with after delete trigger?

I have a system in which users can enter records into a database via ajax. Each user may hold many values in the database, with different pageId and itemId values. Each user is identified by a GUID set to a cookie. The system needs to prevent the user from entering two pieces of data with the same pageId and itemId, so I've created a script to do two database updates:
Firstly, all records are deleted from the database where the memberGUID, pageId and itemId fields match (i.e. they've already added this item).
Secondly, the record is then recreated.
It all works brilliantly, except when the GUID value is passed into the delete statement, then I just get a caught exception.
So this works:
[Code]....
But this doesn't:
[Code]....
The weird thing is that because the GUID value is being saved in the second database call, it is definitely there and is definitely the right data type etc. Even if I hard-code it into the delete procedure it still causes the whole thing to fail.
why it's failing when I add the GUID parameter in the deletion process?

I have one page which contains 3 panels and 3 buttons. Each panel connects one button. When one button clicks, the relative panel appears and other panels are divisible. For each panel, I design a textbox, a merge button and a gridview. When user input information into the textbox, the gridview shows the detail data from the database and two checkboxes. The next step, user uses checkboxes to choose two different rows of data and click the merge button. I need to show a confirmation message based on the selection user made i.e. Are you you want to merge A to B.
write the code to show the confirmation message which is works perfectly in Page_Load() method. But the problem is the page contains 3 panels. Do I need to write code for each panel to show the confirmation message and put 3 sets of the code in Page_Load?
see my code below.

I am Converting one Windows application to Web Application . In between any of the PostBack events I need lot of confirmation boxes and message boxes how it works in VB.net Windows Application. There are so many msg and Confirmation boxes are there but I can not replace them with javascript promptboxes, because they will execute after the server side code is completed and they cannot stop the server side code execution in between when the confirm, and continue to execute the code after pressing yes button.

I have almost completed a competition entry form however i now find myself stumbling over a label which is to display a confirmation message that the entry has been received.
Stepping through the code using debug/breakpoints shows that the code is running the cycle but the end result of the form is just blank fields.
