How can I tell if a Datagridview Cell has changed?

Question

Is there an easy way to identify if a cell within a data grid view has been changed (A specific property or event)?

I have a table with a lot of rows and the user MIGHT need to change the date. I'd rather not have to store the old date to see if it has changed.

The DataGridView.CellValidating and DataGridView.CellValueChanged events should help you in this regard. Check below for their description. http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.cellvalidating.aspx http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.cellvaluechanged.aspx The former can help you check the value after the value has changed but before you commit the content.

That was what I needed to get started. I'm not sure why my search didn't find that but the link you gave also lists all the events (something I was not getting in my searches). So I can use the CellEnter event to set a temp variable to hold the date and the CellValueChanged to compare the new to the old and flag that row as one that needs to be saved. Thanks!! Edit: I ended up using Edit Begin and Edit End events to reduce how often it triggered but the gist was the same. Thanks again.
