Add Event handler to grid filters

Please help me…

I need to set empty text for every filter component. I could not find any methods in in dhtmlXGridObject to set empty text.
So, after the grid columns gets created, I have to get each filter and set empty text add some style.

when the filter gets focused i should able to remove these empty text and style.
when the filter gets empty i should able reset the empty text and style.

And i want to prevent the events when the empty text being set.

How to do this…?

Thanks,

Unfortunately the only solution is to customize the current filter changing the inner dhtmlx code or create your own custom filter.
