load data on the data grid which is on ctrlBeta by the buttonclick event of the button in ctrlAlpha

Hi,

I have 2 User controls say ctrlAlpha and ctrlBeta. ctrlAlpha has a button on it and ctrlBeta has a datagrid on it. I want to load data on the data grid which is on ctrlBeta by the buttonclick event of the button in ctrlAlpha.

How can I do this?

Thanks
