Silverlight
You can use the hierarchical data display capabilities of the NetAdvantage for Silverlight xamWebGrid control for this.
How can I use xamWebGrid to create a tree-table?
Thanks in advance.
Hi,
The xamGrid doesn't support hierarchy specifically like the image you posted. It's more like this:

With a bit of custom code you could make it look like this: https://www.infragistics.com/samples/silverlight#/grid/self-referencing-data
However, the expansion indicators won't be indented.
