I'm trying to create a calendar report in VB using Visual Studio 2010

This is my design so far:


This is the datatable i'm sending in:


But this is the result I'm getting:


As you can see, the columns are only displaying the first row, even though I have set every single one of them to CAN GROW. I also tried moving them to details section but it sparates the days from the values I need to display. Any idea why this is happening?
