We all know that CommandArgument Property can remember value or index, but sometimes, there's nothing in it, do you know why?
Today, i study for a while, and i find the following two ways.
  • Use <asp:ButtonField CommandName="CMD" />, the CommandArgument will memory the RowIndex of the GridView automatically.
  • Use <asp:TemplateField><ItemTemplate><asp:Button CommandName="MCMD" CommandArgument="Value"  /></ItemTemplate></asp:TemplateField>, the Argument value is Value
