About DataGridView

Hello Everybody,

I am a person who has never used DataGridView
Now I am Learning something about it

I want to have some equivalent code and its understanding

First of all I have a textbox and a listbox
I am able to search every Item in a listbox using textbox
Now I want to have more columns in a listbox which is impossible for a newbie kind of guy like me.
So I took the advice from some Master Programmers and decided to use DataGridView

Lets say I have some code as below

If not listbox1.selectedIndex = -1 then
   If not listbox1.selectedIndex = 0 then
      listbox1.selectedindex = listbox1.selectedindex + 1
   end if
end if

Can any help me for the equivalent code for the datagridview

Thanks in advance.
