This works fine, as long as we just "view" the data. Well, you'll just have to go through the controls collection of each cell to get a reference to the controls placed inside it. when you don't use the data source controls those collections aren't filled...that's thw way it is...unfortunatelly, that is... I suppose it would be possible to extend the Grid View control and write methods that fill the collections manually... Maybe it will be something they add before the release date... However, a recent project I worked on required a few other extensions of the Grid View control (multi-row editing, expanding rows, etc.) so while I was writing my extension I hacked together some code to extract values from a row; it's not very pretty, but it does the job in most cases.
A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.Then update in one hit the database with the dataset (with batch updates). I apologize if the forum screws up the formatting; bear with me. Declare a simple Data Helper class with a method that will return the Data Set you get back from data layer, say Data Helper.I've try to do that, but I haven't find something which could work fine. Get The Data Set(string arg) and then declare the object data source in you markup like: Typically you will need to pass some kind of parameter from the UI to the method that will get you the data. thank you :) event is fired the changes have not yet been committed back to the datasource.
Notice that the programing is not running the event Row Updated any help?
For this situation, many developers use invisible columns (Hidden columns) in the gridview to identify that row.
