Application/QTP - Java Applet/9.5

In my application there is a facility of changing the format of the Cell.

for e.g if the data in the cell is say "1000". If that cell is selected and '%' toolbar button is pressed, it will display "1000%" in the cell, similarly if user clicks '$' toolbar button, it will display "1000$".

Now when i'm fetching the value from that Java Object grid table cell after the format button is pressed using GetCellValue, it fetches only "1000".

How can i test the above scenario to check whether '%' or '$' symbol is displayed inside the cell?

Any help is really appreciated.
