Hi everybody,

I have a grid and I placed Valid method for several columns (in their textbox control - I use default textbox). Today I noticed, that this Valid method fires each time, I tab between columns or navigate in a grid. Most of the time my column are readonly, only under cirtain conditions I allow to edit text content in a column. I'd like to fire Valid method only in cases, when something was actually changed in a grid textbox, how can I achieve this functionality?

Thanks a lot in advance.
