Select all rows and deselect all rows option in listview

Question

I have a list view with a check box in each row to select that row... And i have a select all check box above the listview to select all the rows at a click and vice versa... is it possible to do so...

Answer 1

ListItem item = default(ListItem);
foreach ( item in MyListView.ListItems) {
    item.Selected = true;
}

you can use checkbox id instead of item and set it checked or vice versa.
