I'm trying to bind data from a two-dimensional List structure to a grid but its not working out. This is what I'm trying to do in the NeedDataSource event for my grid:

    
                        List<List<object>> rows = new List<List<object>>();  
        
                        List<object> list1 = new List<object>();  
        
                        list1.Add("testing1");  
        
                        list1.Add("testing2");  
        
                        List<object> list2 = new List<object>();  
        
                        list2.Add("testing3");  
        
                        list2.Add("testing=42");  
        
                        rows.Add(list1);  
        
                        rows.Add(list2);  
        
                        radGrid.DataSource = rows;

I'm hoping to get output that looks like:

testing1 testing2
testing3 testing=42

Instead I get:

Capacity	Count
4	2
4	2

Can anyone tell me how I can do something like this without using a DataSet or DataReader?

Hi Rubens,

I am afraid that you need to handle the DetailTableDataBind event and additionally assign the particular detail GridTableView corresponding Orders collection. However, you can retrieve the Customers collection from database on NeedDataSource event and save it in a private variable. Then use this variable in the DetailTableDataBind.
