Ive been trying to understand this thing for approximately 1 day, but i cant really get it
I'm about to create a report which requires TWO tables.

but i forgotten that the datareport.datasource only accepts One command.

so ive got the idea of creating a child command and create it relation on fields.

but when i run it it display an error. :(

'INVALID DATASOURCE'

can someone please send me or teach me how to use CHILD COMMAND?

im begging you, im about to pass my project tommorow :(

Thanks in advance. :(

Show me the code you have used to set the grids datasource etc.
