Unfortunately, there isn't too much in the internet about this topic. Either it's very abstract and difficult to transform in real world applications or it's a very simple description of MVP that lacks any information about all the surroundings. There are also quite a few different approaches (classic MVP, Presenter First, Passive View, ...). Therefore, I can't point you to a good article about MVP. Maybe I should write one on my own :-) -^-^-^-^-^- no risk no funk

:doh: Don't answer to such a dum question! I wasn't paying attention and data types were not matching ;P Sorry for wasting time

I had to answer to this one myself, this is too funny. My stored procedure was calling another function I wrote that had a similar name :omg: It was a pleasure wasting everybody's time ! :rolleyes:;P

Hi Johnny, Tables(0).Columns(0).ReadOnly= True Now bind this datatable to the Datagridview. The column 0 is readonly and will not enter into edit mode. rAm i Think, i Wait, i Fast -- Siddartha

Makes sense, thanks for the input

Hello, ~Johnny~ wrote: I tired different things like adding dataGrid.Scroll -= new ScrollEventHandler(dataGrid_Scroll); dataGrid.KeyPress -= new KeyPressEventHandler(dataGrid_KeyPress); beofre assigning dataGrid to the new FinderDataGridView object but stil doesn't work. Although, it is not solving your problem, you should always unregister the event like this, bevor creating a new instance, cause the old instance will not be cleared by the GC. I think the problem could be that you are not removing the old dataGrid instance out of the datagridSplit.Panel2.Controls. If your dataGrid instance has a dispose method, you also should call it. Hope it helps! All the best, Martin

Hopefull that this helps someone in the future, all I had to do is EndEdit() on the master BindingSource! A bit stupid from my part or was I :zzz:

Scary!

If you were using a DataGridView you'd be able to use the DataError event (I think that's the name) to capture it. You may have to handle it manually on a 'Save' )by checking a value isn't null before committing to the DataSet / DB) if you're using your own custom GUI for editing rows.

Use nvarchar, then there's no padding. Christian Graus - C++ MVP 'Why don't we jump on a fad that hasn't already been widely discredited ?' - Dilbert

Have you tried using the .Select and .SetFocus on the Load event? - Eitsop What we do not understand we do not possess. - Goethe.

Youw should handle the DataGridView.EdittingControl.KeyUp event in your code. Regards:rose:

I wanted to avoid wriring but it's not too long to do so let's get busy !

Have you tried reading all data into a dataset? You can then create a constraint between your two tables (or more) and find parent and child rows using a certain datarelation between those tables. - - - --[ i love it when a plan comes together ]-- - - -
