Asp onrowupdating not firing

This article explains how to perform insert, update and delete operations in ASP. Let us take an example to perform CRUD operations using Entity Framework Database First approach.Suppose we’ve to work on Customer table having Category ID as foreign key.I have a requirement where i have to update a textbox if any of the value in my grid view changes.. one a template field with label and another template field with a textbox...

If any of the columns are hidden, the save button doesn't work correctly. The idea is to only allow a command to be performed on specific people. I'd prefer a declarative solution to a procedural one. For me converting the commandfield to a templatefield control is not an option, as the commandfield comes with built-in functionality that I would otherwise have to create myself, for example the fact that it changes to "Update Cancel" when Edit is clicked, and that when Edit is clicked, all the cells in the row which are labels become textboxes, [email protected] Well, it's calling the code behind method every time. However you should pay attention to the implementation of the method. In my approach, you can leave the commandfield as is, then you can hide it as needed via code behind.The Grid View control supports the following features:use Row Editing, Row Updating, Row Deleting, Row Command, Row Data Bound, Row Canceling Edit, and Pagination in a Data Grid.From this article, you will have a clear view of the Grid View data insert, delete, and update operations.

Here my questions is when someone enters a value in the textbox an event should be fired! i dont want to have an edit link or update link because all the values to be entered are mandatory! selectedindexchanged fires when the index of the selected row changes, which hasn't occurred in this instance.
