Scheduler in a Datagridview

[CnB]

Does anybody have any examples of how to get a scheduler in a datagridview?

 

I want to have a datagridview(probably 3) Month, Week and day(these 3 similar to how Google calendar looks).

 

I have seen it done, but for the life of it i cannot figure it out myself.

 

I know there are licensed components which offer these things for windows forms.

But honestly that's a bit to expensive for me, and i rather code it then drag/drop it.
