Data Manipulation using ListView Server Control with ASP.NET 3.5
page 1 of 10
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. This can be found by visiting the following link.

".............s. Another key aspect for any edit operation is that we should know which row in the database should be updated".. For this purpose, we could store the primary key for each row in the ListView inside a hidden label control or even a hidden server control. "

Ever Heard of DataKey??

When I download and attempt to run the demo it doesn't work! Please try embedding an SDF file into your project rather than trying make users connect to a nonexistant database on their machine.

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.
