Answer 1

in order to get a certain column when selecting a row you need to fill the property datakeynames with the property of your choice.

msdn

getting the value of the property:

void lstvwShopItems_SelectedIndexChanged(Object sender, EventArgs e)
  {
      string value = lstvwShopItems.SelectedValue;
  }

don’t forget to set the OnSelectedIndexChanged on your listview to this method in the codebehind..
