CRUD operations of Data Grid is not a big innovation, but there are plenty of ways to do that.
This post explains how to perform CRUD operations using Infragistics Web Data Grid control in ASP. This code is written using Infragistics version 12.2 Create a simple Web Data Grid.
Data Grids are vital controls in many user interfaces.
Like it or not still 2D tables are one of the most comfortable user interface elements in not only viewing data but also in performing rapid inserts and updates.
In this article, we will explore how to add, update, delete and select a record from sql server database using gridview control in a simple way.
I’m using visual studio 2008 and sql server 2008 for this sample.
Edit Item Template: When we select or edit a specific row, the contents of this templates are displayed in the gridview.I believe that databinding on every postback is the cause but that's not something that I can change right now, same goes with the autogeneratedcolumns setting. I'm not sure if I know what you mean about 2 way binding. If you meanam I using Bind instead of Eval in my HTML, then yes. And the result of your code is no different than my version or what I was doing before, which was just using the findcontrol method, and that just returns what was in the grid when it was first binded to the database on page load. Yes ok i think i know what you are probably doing wrong. I'd like to know if there are any other ways to retrieve the new values? I have been using the web site successfully for just over a year, and I am presently using a Select button in the row to launch a detailsview, and I edit the database that way. Net a year and a half ago, and VB programmer forever before that, but I feel pretty confident in this large and powerful website I have created, but the users don't like the details view have expressed a desire to edit on the fly in the gridview. My user base has a hold of management's ear, and my management wants to dump ASP. This could be the straw that broke the camel's back - a person's job hangs in the balance - MINE!! If you are databinding in page_load then you need to only do it if(! In the View Model class Carton View Model Guid property is used as the object identifier in the collection. NET Session) For the new rows we set the Carton Info Id to –1, because this is an identity column in the database.
When we update the objects which are stored in the database already we can’t change the Carton Info Id that’s the reason why we use a separate Id property for the View Models.
This is the View Model class used for data binding.
