Data format for plus/minus

How do I need to arrange the data to support the plus/minus feature? Do I need multiple tables, relationships?

Currently, I have one table with three items (name, item, id) in a single table, with multiple entries per name. I want item and id to be sorted as child items for each name. Do I need to break up my table? If so, into what? Thanks. Any comments appreciated.

Hi Matthew,

Please refer to the GroupCustomers browser sample for more detail.
[install path]\Syncfusion\Essential Studio\4.3.0.25\windows\Grid.Grouping.Windows\Samples\GroupCustomers\cs

Haneef. Thanks for the reply, but we are currently using version 3.2.1.0, and I do not find this example in the grouping samples directory. Is it possible to download the sample from elsewhere?
Thank you, Matthew.

Thanks Haneef,
I figured out the problem. I had set: "Me.Grid.ChildGroupOptions.ShowCaption = False", without realizing that by not displaying the caption I was also removing the capability to group items (and, by extension, to have +/- buttons for each group). Problem solved now, thanks again,
