checkboxes on list

how do i check all the boxes avaliable on a listview or uncheck all at 1 time? is there a simple function for it or i have to use a for loop a check all 1 by 1?

I think you have to use a loop and check all of them manually. :(

Check/uncheck all items in a listview:

VB Code:

For i = 1 To ListView1.ListItems.Count
    ListView1.ListItems(i).Checked = Not ListView1.ListItems(i).Checked
Next

can you explain the codes please......
i dont understand the logic

thanks alot it works

    ListView1.ListItems(i).Checked = Not ListView1.ListItems (i).Checked 'if the checkbox on listitem(i) 
                                                                         'is checked, it will uncheck it, 
                                                                         'if it is unchecked, it will check it
                                                                         'Using Not is like saying set the value
                                                                         'to the opposite of the current state
Next 'start the loop over...
