What are the events handlers I need to insert / update / delete rows in a
datagridview? Seems a lot different than asp.net. I can initially bind
the datagridview but don't know the event handlers to add/update/delete.
I'd appreciate any insight. Thanks a lot.
If you create your own made data source, one way is to implement
IBindingList and to define an empty constructor (to add new "row").
BindingList><T> does implement IBindingList. You can use BindingSource to
expose IBindingList on types that do not implement IBindingList. Here an

the original grid, and apply the updates the minute we hit save.

I was thinking to pass the datasource across into the pop up form - but this

Simply one row deleted from datagridview.

How I can add rows in a DataTable bound to a DataGridView from another
thread. If I directly add it, my DataGridView stop responding. I am looking
something Invoke kind of method.
Datagridview binding is quite simple when using classes that expose fixed
attributes using BindingList.
Suppose I have a Field that exposes Name and Value attributes. Now, I also
have a class Fields which is basically a collection of class Field as you can
Fields : KeyedCollection<string, Field>.
So far everything is fine. But now I want to implement a collection of
Fields, which are Rows basically (something like a DataTable) that I can be
able to bind easily to a DataGridView.
How can I achieve this?

I have a standard DataGridView. One of the columns is a
DataGridViewComboBoxColumn. When I select one of the ComboBox items, I want
to trap the change and add additional columns based on the item selected in
the ComboBox. I've tried using CellValueChanged for the DataGridView column,
and a bunch of other events, but none of them is fired when the
DataGridViewComboBox value is changed. What event can I trap to make this
happen? Right now as I said, I am using CellValueChanged, but of course the
event doesn't fire until I click on another cell...
