How to delete only selected items from listview?
<p>Hi i want to check all items of a listview.For that I am using menu.<br>
If select all menu is choosed then all the data have to got selected. Again if I choose delete from menu all the values of the listview have to be deleted.<br>
I am selecting the listview items correctly. But if I unchecked any of the checkbox and chose delete it say "Please select an item". It is a bug.<br>
That means if i select all items and then uncheck any only one item of the listview, the checked values have to be deleted.<br>
I dont know how to do it.</p>

<p>Please help me if anybody knows.</p>

<p>Code:</p>

<pre><code>private void CreateMenu(Menu menu) {
        menu.setQwertyMode(true);
        MenuItem mnu1 = menu.add(0, 0, 0, "Delete");
        {
            mnu1.setAlphabeticShortcut('a');
        }
        MenuItem mnu2 = menu.add(1, 1, 1, "Select All");
        {
            mnu2.setAlphabeticShortcut('s');
        }
    }
