Hi,

I cant test on it because my project no longer working after I compile SF source code. I got to reinstall SF.

Hi,

I am able to "hijack" the value of TopMostValue to change it from "-1" to "00000000-0000-0000-0000-000000000000" and it would work.

I would wait for your next update.

Thank you

We would have to test this on the GUID as this was not designed with this in mind.  You can just create your own top most item instead of using the property.

Hi,

Which event should I place the code to create my own topmostitem?

Do you meant to modify SF source code?

Thank you

No, do not modify the SF source code.  I was referring to adding an item to the data source that is shown within combo.  Just another another item.

Sorry, I am lost.

Why to add another item to my datasource? My PL field is GUID. How to assign "-1" ? hmm... didn't get you.. sorry.

To add your own item, you would need to handle the DataSource changed event on the ComboBox.  Within the event, you can add a new record to the top of the data table (.Insert() it rather than .Add() it).  You can check the structure of the table for the field names, but it should only have two columns... a "display" column and a "value" column.  Then, just set the values in the new record and insert it into the table.

Hi,

May I know if this issue been handled natively in upcoming update?

Thank you

Hi

Sorry, I still don't know how to solve this problem.

Where should I put my code? How to set Browsedialog combobox.topmost to Guid.Empty instead if '-1'?



Thank you

Hi,

Since the combobox in browsedialog is created at runtime while ShowDialog() method been called, how could I handle its DtaaSourceChanged event?



Also, FYI, the error is occured at ListControl.PopulateComboFromBusinessObject().
