If I have a gridview with a default mode set as (Edit).

I don't want to use the Edit,Update,Cancel buttons in the gridview , I simply want to add a button somewhere in the page , and once that button is clicked the gridview contents should be updated as if I clicked on the (update) button which belongs to the gridview.

I thought I can call the UpdateCommand !! because I simply want to execute this command and that's it.
