I have a report control in my project which has some rows / records with child rows / records .  if any parent row has childs , then a plus / minus sign is displayed on the parent row . we can expand / collapse child rows clicking that plus / minus sign .

 

Everything is working fine if my computer regional settings are set to English / United States . But if i change my regional and language options ( in contol panel ) to Franch / France , then plus / minus sign is not getting displayed on the parent row , Although child rows are getting displayed and i can still collapse / expand child rows using arrow keys on keyboard . But Plus / Minus sign is missing .

I tested report control sample projects with French settings and it works fine and plus / minus symbol is displaying for parent rows . Not able to figure out why this is happening with my project , that too only when regional settings are set to French .

 

Does anyone has any info on what is causing this and how to fix this issue ?

 

Thank you
