vb.net - how to get data from selected row from datagridview -

i have new problem, have datagridview, try see picture, want when cells exist in datagridview on click, click on data entered textbox1, know how how? helping me

i tried below, not work

private sub datagridview1_cellcontentclick(byval sender system.object, byval e system.windows.forms.datagridviewcelleventargs) handles datagridview1.cellcontentclick         if me.datagridview1.rowcount > 0              textbox1.text = convert.tostring(me.datagridview1.selectedrows)               'textbox1.text = me.datagridview1.rows(me.datagridview1.row).cells(1).value         end if     end sub 

to cell value, need read directly datagridview1 using e.rowindex , e.columnindex properties.

eg:

private sub datagridview1_cellcontentclick(byval sender system.object, byval e system.windows.forms.datagridviewcelleventargs) handles datagridview1.cellcontentclick    dim value object = datagridview1.rows(e.rowindex).cells(e.columnindex).value     if isdbnull(value)        textbox1.text = "" ' blank if dbnull values    else       textbox1.text = ctype(value, string)    end if end sub
