I have a dataset consisting of three tables.

Table 0 has a single row
Table 1 has multiple rows
Table 2 has multiple rows

All 3 tables have a common OrderID integer key that joins the data and we are using DataKeyNames="OrderID"
for the mastertableview as well as the detail tables.

What I would like is an indented presentation of these rows

Table 0 - Order Info
              Table 1 - Product 1
              Table 1 - Product 2
              Table 1 - Product 3
                            Table 2 - Payment 1
                            Table 2 - Payment 2


What I have working right now is a grid that keeps repeating the top row (table 0), and is quite inefficient in its presentation. An order with 4 items will repeat many of these rows. Its confusing and redundant. How can I get the grid to display in a more nested fashion with this type of data?

Hello Karl,

The desired hierarchy structure can be presented in RadGrid through parent table relations or DetailTableDataBind event handling. You can generate the content for each table in the grid structure and populate it with data in par with the relations in the grid source. 

Detailed information about this common type of Telerik RadGrid hierarchy you can find in the Populating the control with data chapter (topics Advanced Databinding (using NeedDataSource event) and Hierarchical data-binding using DetailTableDataBind event) as well as in these online examples:

I hope this helps.
