[Solved] Setting an image Url for a listitem

[Oded]

Hello,

I have a two listboxes that I use to transfer items from one to another. On my destination listbox I want to set one item as a default item.
I have decided to add a button that will take the selected item and set an image to it to indicate that this item is the default one.

I have done so using javascript:

function setDefaultReport() {
                selectedReportsList.trackChanges();
                var selectedItem = selectedReportsList.get_selectedItem();
                if (selectedItem) {
                    if (defaultReport) {
                        defaultReport.set_imageUrl("");
                        }
                    }
                    selectedItem.set_imageUrl("/images/icon.gif");
                    defaultReport = selectedItem;
                }
                selectedReportsList.commitChanges();
            }

When I push the button to run this function I get an invalid argument error during runtime of the script. It happens in the insertBefore function of the current list item.

Any ideas?

Thanks,
Oded

Have you tried doing this server-side as in this demo? Since you're clicking on a button already that could be viable option.

Server side solution is not relevant in this situation. Any way, I have decided to use checkboxes instead.

Thank you.
