I have grid that contains a column value that is supposed to be readonly.

I have tried to set a breakpoint to tell me when this value changes erroneously to .f.

I can access the column in the watch window as follows.

_screen.Activeform.Itemgrid.Unitcolumn.Unit.readonly

However when I try to set a break point using this , the breakpoint dialog strips off the _screen part so the expression is not evaluated.

Can anybody tell me a way of doing this.

I have tried setting asserts at various points in my code to trap this elusive event but to no avail.

I realise that I can step through the code a line at a time whilst checking the watch window but this will be a long process
