Hello,
I use a WHDG bound to a self referenced SQL DataSource (like a simple table ID,ParentID, Name).I allowed editingcore & rowadding behaviours and set the EnableInheritance Property to True.
My problem is that i can't add row under records that have no child records.... As there's no children under those records, there's no row island and no more AddRow...
I assume that's a bug, because it works with a WHDG bound to 2 sqlDS like (Orders and OrderDetails).
Can someone help me ?
Hi gvi,
I attempted to replicate this on my end, but did not have any luck. Could you maybe send a small sample our way?
regards,David Young
Hi David,
Here's a sample.
Moreover if you could explain me how to set the default value of parentID to (null) for root creation record, it could be fine.
I hope that you'll help me, cause last time you asked me a sample, i uploaded it and i'll still waiting.So, please have a look to all my recents posts (since june) in the asp.net forums :)
Regards,
Gregory
Hello Gregory,
I see that you created support ticket CAS-69700-13Q3Y3 for this issue. We will continue our discussion through the support ticket
Hi Dave,
After more tests, your purposed solution is not sufficient.
Cause after adding a row with the addrow on the added band (used for items that have no child), I have no expandable icon and so I'm not able to add a child row to the newly created row.
Have you another trick ?
Gregory.
It don't works.
Could you provide me a working sample ?
In the code behind, in Page Load, do the following.
this.WHDG1.Bands[0].RowAdded += ...
You need to add the event to the band that the child is created from. Or you could handle row island created and add it to the ContainerGrid there.

Now I can Add Row correctly, I want to handle RowAdded/updated/deleted events on server side, in order to display error messages like in this samplehttp://help.infragistics.com/NetAdvantage/ASPNET?page=WebDataGrid_Handling_Server_Side_Exceptions_Using_AJAX.html
I get events on the root items and the root addrow, but for child items I never get those events...
Please help me...
