If I open a spreadsheet in Excel containing a multi-select ListBox, remove a selection by clicking on a selected item, then save and open the same worksheet from Aspose, the ListBox.IsSelected() method thinks the item is still selected. Please see attached example program. BTW, I am using the latest release of Cells.
Unzip the solution
Open C:\Aspose Issue\ExcelListBoxIssue\ListBoxIssue.xlsx in Excel
Click on the J2 item to deselect it and save the file.
Run the example
Note the value of lst.IsSelected(1) is still selected
