Q: 

datavgrid iew control bounded to a collection question

Hi All, I'm new with DataGrid View control, and I've this problem:

I would like to build a C# application with this control, bounded to a custom collection. If I change the data in the collection, I would expect that the grid should change in accordance. No problem in implementing this.

The question is, this control comes with the possibility to catch the changes and trigger a procedure, with the grid-cell that has been changed?

Many thanks, and sorry for my poor english.

Regards stefano

A: 

It sounds like you want to know when a particular cell has been edited. This event should do just that:

CellEndEdit - Occurs when edit mode stops for the currently selected cell. http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.cellendedit.aspx

Thank, but doesn't works. This Event is triggered when I edit a cell. I would an event that fires when the collection bounded to my control is changed at runtime...

What type of collection is it?

Or you can catch DataGridView's CellValueChanged event.

same as before. There a way to implement the CollectionChanged event??

I think you mean the PropertyChanged the event? Basically, your collection needs to implement INotifyPropertyChanged. Then when properies of your collection changed, you need to fire OnPropertyChanged event.http://msdn.microsoft.com/en-us/library/ms743695.aspx
