I facing a problem with listview now, now I have data in the listview, when I click on the header of the column1, the search key will be point to column1. Mean that user will search what ever data in column1. When user click on the column2 then the search key will point to column2 no longer in column1 at all. For example, I have 3 column in my listview, 1) Employee No, 2) First Name 3) Second Name, when user click on the header of Employee No, user only can search for employee no not for first name and second name, by the way, user click on the header of first name, the user sure only can search for first name, and no more for employee no and also not for second name. Can anyone help me on this? Thanks.
