Which event is raised after a DataGridView sorts itself?

[Guest]

Hi, I'm using vs2005, .net 2, C# for windows application. I have a
DataGridView control that its datasource is from a dataset datatable. After
the user changes the data on a row in the grid, the grid sorts itself based
on the new updated value.

Anyone knows which event is raised after the grid auto-sorts itself? I need
to highlight some rows on the grid after it sorts itsefl. Is this possible?
I tried the grid's Sorts evet and that was not raised.

It is entirely possible that no "sort" is happening here... if the
DataView is simply updating itself, then this could be responding to a
ListChanged event (of type ItemMoved and probably also (separately)
ItemChanged) on the source. Try listening for this event on your
DataView.

And note; DataView was not a typo... I mean the data-source that you
are binding your DataGridView to; when using a DataTable, this
actually returns a DataView via the IListSource interface. You might
have known this - I am just clarifying.

Marc, Thank you for clarifying that. I'm glad you did because I thought that
was a typo at first. Actually, by code, I created a DtatView and set that as
the datasource of the datagridview control.
I see that thre is an event of ListChanged in the DataView. How do I add
code for an event of that Dataview?

Hi Marc,
I was able to add the event for dataview_ListChanged(); However, the data
is updated or changed in the grid by user draging and droping so the
ListChanged event is raised before the drag_drop is completed and the grid's
or the dataview's self-sort is done after the drag_drop event.

I'm really not convinced that the DGV is doing a "self-sort" as you
put it; that is the job of the DataView... in a bound scenario (to a
suitable source, such as a DataView) the DGV doesn't ever do the
sorting - it merely asks the view to sort itself.

Is there no ItemMoved notification? Alternatively, you could force a
reset (somehow - rebind perhaps)?
Can you perhaps hint as to exactly how your drop is adding data?
(there are countless ways of doing this...)

Hi Marc, My bad. I meant to say the Dataview is sorting itself. What you
said makes a lot of sense. I just had a type. Sorry about that.

I'm using the DragDrop of the grid. I now just search through the grid (row
by row) after the DragDrop is completed on the Target grid. All the droped
rows will be marked as mapped in a not visible column named "Mapped". I then
checked for a mapped column (invisible) of each of the grid row and if it's
marked true then I hightlight those rows. I'm just about to try and see if
that work.

That seems to be working. I have to loop through all the rows in the grid
and could be a performance issue but I can't seem to have any other way to do
this with better performance though.
