Asp net gridview rowupdating new values empty intimidating tennis sayings
The key fields are defined in the Data Key Names property of a Grid View control.The Old Values property is automatically populated with the original values of all the field name/value pairs in the row.In this article, I am going to explain how to insert, update or delete a row from a grid view control. At run time, the Eval method calls the Eval method of the Data Binder object.If you are new to using a grid control, I would recommend you to read my blogs “Using Grid View in ASP. The Eval method takes the name of a data field and returns a string containing the value of that field from the current record in the data source.A separate entry is added to the Old Values property for each field in the row. Dictionary Entry object contained in the Old Values dictionary.
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(! I know its very annoying and hard to get the data out of the data controls (gridview in this case), but there are other things you can do to make it easier. The reason is we don't fill the values unless your are bound to a datasource control. I've attached my code for what it's worth, but it will probably be too dificult to determine everything that I am doing. Is there a flag I can turn on or off when I am doing row updating so that I can detect and not rebind?
