Problems with CommandButton in DataGrid and DataList

This problem I encountered today is very depressing! Is it an improvement of FrameWork 1.1 over 1.0?

In DataGrid or DataList, there are ItemCommands, such as Edit, Select, etc.
But it can only run normally when using <asp:LinkButton>, but not when using <asp:Button>!
For example, <asp:LinkButton CommandName="Edit" Text="Edit" Runat="server" /> can be used normally.
