Thanks for the answer, i will wait for the update.
I have another problem with rdbgrid, tested the demo you provided as well, and has the same problem.
When you have an active filter on a column, with empty value for example, and you change the value of a row in the filtered column, post it on the change, and move to the next row using the down arrow, the grid jumps two rows instead of one.
