AdvGridFindDialog Controls.Disabled???

I have a table with about 140 columns (Yes, it's normalized!) displayed in a DBAdvGrid and I need to look for a word in all rows and columns.

The AdvGridFindDialog looks in every row and column and stops when finds it. So far so good, but it runs like crazy showing each cell it's examining and without a way to stop it!
Is it possible to use a property or a event like Dataset.ControlsDisabled for the grid to prevent the user to see what cell is being examining and enabling the grid again when a cell matches the word that we are looking for?
Best Regards
