[Solved] Hierarchy, binding to object without ID fields

[Matt]

So I'm trying to use a RadGrid for displaying an object with nested Lists as properties. I have it in a user control so I'm declaring RadGrid in code-behind. The object is passed in through the user control's constructor, all of the data is contained in the object, there is no need for any lazy loading. The object is retrieved from MongoDB so there are no identity fields at any of the levels in the hierarchy (other than the database _id at the very top). So when looking at the demo "Grid - Creating Hierarchy Programmatically", I get stuck at creating GridRelationFields because, as far as my data is concerned, relations aren't necessary.

Does the RadGrid have functionality for using reflection to display the full details of the object I'm trying to bind to it? Is there some way around having to create GridRelationFields? Or will I have to make wrapper objects and programmatically generate and assign ID fields to get this to work?

Hi Matt,

When you use programmatic binding of hierarchical RadGrid you do not need to set GridRelationFields. In your case into the RadGrid.DetailTableDataBind event handler you need to pass the collection of child related items to the e.DetailTableView.DataSource.

I hope this helps.
