Datagridview

Hi all,

Is there a way to retrieve the rowstate of a row in a datagridview
(added - modified - deleted - ...) ?
Does someone have some info on this or a document/url where I can read
about it?

Thanks in advance!

You're confusing a DataGridViewRow with the underlying data source. A
DataGridViewRow does not have any such properties. A System.Data.DataRow
does. But you need to confirm to us that your DataGridView is bound to a
table first. If so, the DataGridViewRow has a "DataBoundItem" property which
is of type "object." If it is bound to a DataTable, the DataBoundItem
property will be a DataRowView (most likely). A DataRowView has a "Row"
property which is the underlying DataRow. And *that* has a RowState
property.

Thanks!
The DataGridView is indeed bound to a DataTable.
I will try this when I'm back at work in a couple of days.

Thanks for the answer, I'll let you know if it works!

It is exactly as you describe ... the only problem is that when the
datagridview is bound, the rowstate of all datarows are of type "added".
When something is changed in the DataGridView the state of the underlying
row still is "added".
Am I doing something wrong here ?

Thanks
