GridView row delete

I have defined Edit and Delete function for each row of a GridView as below -

<asp:GridView ID="PGridView" runat="server"  
          ... ...
<asp:CommandField HeaderText="Edit" SelectText="Edit" ShowSelectButton="True" />
<asp:BoundField DataField="id" HeaderText="ID" />
... ...
<asp:TemplateField HeaderText="Delete">
              <asp:LinkButton ID="LinkButton1" CommandArgument='<%# Eval("id") %>'
                CommandName="Delete" runat="server">Delete</asp:LinkButton>

My question is -
When I click the Delete LinkButton, it seems functions for both OnRowCommand and OnRowDeleting are executed. If I removed OnRowCommand, I got error. Should both functions always be present? If yes, what should usually be there in both functions? I just need to delete the row.

OnRowCommand means that a row command has happened.  (You can even have your own custom commands).

the OnRowDeleting event occurs when the row is being deleted.  This one isn't necessary, but you can do different things here (eg: kill children rows if you have a nested table) or reload your source, etc.
