Hi:

I have implemented a class taken from msdn website that inserts a combobox
into a grid cell and binds the value property to a column. It works except
that when changing rows using arrow keys it will bomb when a combobox is in
edit mode. I get error saying current row number doesn't match currency
manager, but when inspecting in debugger it does. Has anyone come accross
this?

Thanks,
Charlie

Before calling SetColumnValueAtRow in your SetColumnValueAtRow override,
check whether your cached row number equals the CurrencyManager's position.
If not, don't call SetColumnValueAtRow.

Hope this helps,

Thanks! I just forced currency manager = row number where error occurred.
It worked, but will try your idea too. Looking forward to switching to new
grid in 2.0.
