datagridview data read

Question

Hi all, I have very silly question.

 

To read data from gridview:

string lsvalue1 = datagridview1[0 , 0].Value.ToString();

it reads column1, row1 data from gridview. What the syntax if i want column0,selectedrow  data? for example  string lsvalue1 = datagridview1[0 , currentrow????command].Value.ToString();
Cheers
