RadzenDataGrid double

Hello, I hope can you help me. Im trying to insert the value of two different source of data but i can only do it in two different datagrid tables, i want it in only one datagrid, how can i do?

I'm not sure what you are trying to achieve however if you insert new item in the collection assigned to DataGrid Data and execute Reload() the new item will appear in the DataGrid.

Oh sorry I only want one DataGrid but I've only been able to make two DataGrids, how can I get the data without making the two datagrids?
