Dropdown issue in mac os

In one of our functionality we have provided export to excel features using aspose.cell. we can successfully completed the implementation but we are facing issue when we open the exported excel file into MAC OS.

Issue is related to drop down controls when we click on the drop down, The control is opening up and closing automatically like flashing on the screen. Its should be remain open until user click on other area within the excel.

Please find the attached video for more clarification.

Thanks for using Aspose APIs.

Please unhide the worksheet i.e. Sheet1


and then check if it works fine at your end.

Please also share the code with which you are creating the combo boxes. It will help us look into this issue further.

Below is code that we have implemented in C# for creating the combo box.

                       ComboBox cb = worksheet.Shapes.AddComboBox(7, 0, 1, 1, 18, 180);
                        cb.InputRange = "Sheet1!A1:A2";                            
                        cb.Shadow = true;


Thanks for the sample code and using Aspose APIs.

We will look into this issue and update you asap.


Please try the following code and let us know if its output is valid or not at your end. I have also attached its output Excel file as well as screenshot for a reference.

Please make sure you are using the most recent version. The version number will also show up in the name of output Excel file. i.e. output-17.10.3.xlsx.
