[Solved] clicking add new item does not work when showinsertrow = true

[Valentijn]

Hi

When i click on 'add new item' on the grid below, nothing happens. Is there any reason why this would not work? I thought that adding ShowInsertRow was enough. Editing a row by doubleclicking the row works.

Does anybody know of any reasons why a new item would not be allowed or supported (CanUserInsertRows is true by default) ?

Hi Valentijn,

The ability to insert and delete items depends on the type of collection you use as data source for the grid. Basically, you need to implement either IList or EditableCollection. If this is not your case, I would need more details about your scenario, so that I could provide you with a more suitable solution.

Hi Maya

I'm using DomainDataSource.DataView from RIA services which is based on Entity Framework. I can add items to the collection with Add() command manually. In the gridview, the EDIT is working. If the Edit is working, shouldn't add and delete also work?

Best regards

Hi Valentijn,

The ability to edit the items does not necessarily mean that you can add and delete them. Please take a look at this forum thread for further reference on the way of implementing the functionality of inserting and removing items in similar scenarios to yours.
