AutoSize the LastColumn of Datagridview

Hi

I want to know that how can i make the last column of the datagridview

to adjust the width so that it covers all the space as datagridview

It means it gets fits to control canvas

I don't want to hardcode as the other columns can expand & shrink

So according to the space left

the last column gets autosize to cover the whole remaining space

(So,NO SIlver background of datagridview should be there)

thanks in advance
