Binding GridView to heirarchical collection

[Matt]

I have a collection of say invoices that has a collection of invoice details or line items and a collection of payements.  I want to bind the gridview to the collection without manually creating all of the columns and such.  When I use the Invoice collection as the datasource I do not get the children of invoice, only the single column.  I am setting autoGenerateHeirarchy.  Do I need to define the relationships to accomplish this, even though they are well defined already?

Thanks

The AutoGenerateHierarchy property only works for datasets that have relationships defined between datatables.

More info can be found in the WinForms - GridView documentation: http://www.telerik.com/help/winforms/grid_binding-to-hierarchical-data-automatically.html

Hello Matt,

The auto generate mechanism of RadGridView currently works only with a DataSet object. You must set DataSource to your DataSet object and DataMember to the root Table, in your case DataMember = "Invoices". Your DataSet also must define relations between the inner Tables.

As Tim has suggested, you can find additional information in our online documentation.

Sincerely yours,
