Rowupdating gridview newvalues

But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.

When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.

Note A common mistake that a lot of people do is that they perform a databind each and every-time the Page_Load method is called.

This will lead to problems like "Grid View does not show updated values", "Grid View looses values changed by user". In your Page_load, this is typically only inside a block where you check to make sure that Page_Load is not being called during a post-back call.

You can implement the components of this layer using strongly typed Data Set as well as custom business objects by defining classes in any language supported by . The presentation layer enable display the data associated to business entities as well as control the interaction from the end user and the business application.

The data access layer encapsulates the underlying SQL statements for data manipulation.
