Select/deselect all items

[spt]

I want to add an icons to select/desect all items in the ListBox on the client side. Can you provide an example how to do this?

Hello spt,

What do you mean by Icons? Do you want custom buttons that look like the Transfer/Reorder buttons? Or just a button placed anywhere on the page that should select/deselect? I will prepare example as soon as you clarify your requirements. As for the implementation, here is sample code:

function selectAll() {
            var listBox = $find("RadListBox1");        
            var count = listBox.get_items().get_count();
           
            for (var i = 0; i < count; i++) {
                listBox.getItem(i).select();
            }
        }

I meant buttons looks like the Transfer/Reorder.
I think you can include this feature in the next releases, it is very useful.

Hi spt,

I have prepared sample project demonstrating how to add additinoal buttons for select/deselect all. I will log your suggestion and if there are more customers that require it, we will consider implementing it. You can find the sample as an attachment.
