Hi,

Any sample code to show how to have master and details BOs shown in XtraGrid (in same grid)?



Thank you

Yes, you can chanin these together.  So you may have a CustomersBBS and a CustomerOrdersBBS.  Within the CustomersBBS you can create a property that exposes the CustomerOrdersBBS.  There are two hitches that you have to account for.  First, the private field that exposes the child needs to be shared and second, you have to manually filter out the child records when returning the child object.

This is what we do for all of our reporting and have some very deep and complex relationships and it has worked out great!

Trent,

I got really busy yesterday so wasn't able to spend much time looking at this. Is there anyway you can create a sample of how to use the BBS to create a master detail grid?

I had some issues using the BBS as a binding source that was discussed in another thread. Ben gave me some good suggestions on how to get around the issues I faced but I ended up using this approach to grid binding as it meant I did not have to refactor and then retest quite a bit of logic.

Anyways it would be great to see an sample of how it would work using a BBS.

I will see if I can't get a sample created for the next build so that it is a bit more in-depth.  This is the approach that we use and it has worked well.

Peter,

I got really busy yesterday so didn't have a chance to post this, this is an editable version of the data set class, basically what I am trying to do is to keep the business objects on the form in sync with the data tables in the data set. 

For the most part I think it will work ok but there still may be some gotcha's I haven't ran across. I also threw in a report so you can see how that works.

Anyways I hope this helps out anyone that is looking to do this sort of thing. 

I also am posting an infragistics 2007 volume1 version just cause it was easy enough to do .
