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 开发者_如何学JAVAclick and vice versa... is it possible to do so...

You can resolve this even easier by simply using 2 methods.

listView.clearChoices();
listView.requestLayout();

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.

The object ListView has a method called clearChoices().
