So that means when you bind to some raw collection and hook up to the Data Source property then call databind, if you try to handle the delete or update events these dictionaries are going to be empty.Right now you must be asking yourself how can you get those dictionaries filled out just as if you were bound to a Datasource control?

From the time you write code that depends on the immediate layout of your page then your asking for trouble.Here is a mapping of data control to method used to extract values: Grid View = public Extract Item Values As we can see with the exception of List View these oh so useful methods are protected, that means we can't call them from our code if we are using these built in controls.What can we do to surface these methods: The method itself is pretty simple. Thanks to your article I can go forward with my personal project, so I am very very grateful.Is this compatible with copying data from excel and pasting it in the gridview you are providing us? Setting Enable View State on the Text Box to "True" fixed the problem.

After you've created a layout with a data control of your choice and eventually bound them to some datasource, you almost always want to get that data back out of them(and why wouldn't you, its your data).

I had inadvertently set Enable View State for this textbox to "False".

Because of this, the Grid View was rebinding itself before the UPDATE occurred.

Edit: I've updated the code to loop over the Cells collection instead of the Controls collection (which is alot cleaner).

Also there is no real compelling reason to return a strongly typed IDictionary Let me know if you find any bugs.

On clicking the delete button, i get the row deleted from the DB. I am using a simple Gridview to display the emp id (as a link for selecting), emp name, emp Age. Using the delete button, the record can be deleted. You indicate that it is the former so that your update command isn't executing. NET Grid View - Add a new record I had the same problem.
