Data Manipulation using ListView Server Control with ASP.NET 3.5
|
Published:
27 Dec 2007

Abstract
In this article, Das explains how the good old data manipulation operations (such as Add/Modify/Delete) can be done using the ListView Web Server control. Apart from these, you will also learn how to give a confirmation message before we delete a row from the ListView. And finally, during editing/modifying a row from the ListView, we will see how to set the proper index for a DropDownList inside the ListView Edit Row. All these operations have been explained clearly with a live demo. |

| Introduction |
In order to use the ListView control, we need the ASP.NET
3.5 Framework. All examples mentioned in this article were created using Visual
Web Developer 2008 Express Edition. You could use SQL Server 2000/2005 or
the free SQL Express to try out the examples explained in this article. C# is
the primary language that is being used in this article. If you are comfortable
with VB, then you could use a free tool which will convert the C# code to VB.NET.

I spended quite a lot of hours and your codes are not working. I tried to make it work, but it just doesn't make sense and not working. I found it's better to put Updating, Inserting, and deleting on ItemCommand event. If you want to do all actions in code-behind, that's the best place you should embed the action codes. Your codes are too buggy and don't make sense in general. I hope anyone reading this as a beginner should avoid. Don't waste your time thinking you're doing something wrong. It's just the design of this codes are too nonsense

This is fixed.
Well, this is a design flaw. When we have zero rows, the link to add authors was disabled. This is due to fact that the link to add new authors was in the ItemTemplate. When we have zero rows, the rows inside item template will not get rendered. So, I added an EmptyDataTemplate. Inside the EmptyDataTemplate, I have included a link to add authors. By this way, when someone deletes all rows, the link inside the EmptyDataTemplate will get rendered.

It is a bug in my code. when the record count goes to zero, the link to "add new records" is not being displayed.
I need to fix this, so that the "Add new" link / button will always show up. so, when we have zero rows, we could add new row using the "Add New" functionality.
Will modify the code accordingly.

Greetings,
thank you for the useful article.
in the DataBoundList method you say : if (ddl != null)
but why you do not check if the listview in edit mode so if it is in edit mode so you get the reference to the dropdownlist??
Regards.

The stored procedure got deleted somehow. Not sure how. But I just ran the create script again and the LIVE demo is working fine again.
Thanks for letting me know about the error
