2 0 gridview rowindex rowupdating

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.

But as I noted in the comments in that method, some collections that should contain the columns (names, old values and new values) are always empty. And the Row Updated method is never even touched!!! NET Forums that I need to use a Data Source control.

When adding items to a gridview, I want the user to be able to select and edit/remove the item before writing the file (from the gridview entries) to a csv format.

When I click on "edit" and update the information, I get an error.

For example, the current data is: name: Blake, phone: 123-234-3456, email: [email protected], contact Id: 22 I type in new data: name: John, phone: 555-555-5555, email: [email protected], contact Id: 22 Data that ends up in the database: name: Blake, phone: 123-234-3456, email: [email protected], contact Id: 22 When you raise the Row Updating event your basically getting the values BEFORE the Grid View updates the row.

This is basically so you can cancel the update operation.

For a while now I’m trying to figure out why my method, triggered by the Grid View.

Row Updating event, doesn’t work as all samples say it should do.

The problem is, I’d very much like to do so, if ASP. But I can’t set a Data Source property or anything on the Sql Data Source!!! I probably have to read the cells on the Grid View of the selected row, find the controls, get the values from those and insert those into my Data Set.First, I load up some data: After that, I’m doing some work to make my Grid View look beautifull, adding all columns by hand.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 attached with a Data Source control Grid View performs tasks such as paging, sorting and editing automatically i.e. However, at times you require to bind the Grid View with a Data View or Data Table directly.Fortunately Grid View can also be used without attaching with the Data Source Controls. In this article we will see how paging, sorting and editing can be implemented in a Grid View control that is bound with a Data View (or Data Table) directly.
