posted July 10, 2006 4:43 PM Your code works fine with the latest (unreleased) code. We are planning on a LiveControls update within the next couple of weeks which should clear up your issue. |

posted July 19, 2006 8:59 AM I have just downloaded and installed the latest version of the live controls (1.5.2) and this does not work from me. Note that the first two buttons in the datagrid fire the item command event. It is only the button in the added row (3rd) that does not fire the event. If anyone could help please? |
