Hi,
Tks for your reply
I will describe more details about what I want to do
In GGC, I have column "Value", fill value from 1001 to 1026
When
I CheckBoxClick, or CellClick, or KeyDown on cell "Select", I want
value on current cell "Select" changing and updating on interface, and
on rows that have value match first 3 characters of current cell, value
on "Select" cell changing too
Problem occurs when 1st time I
do, value on current cell updating in BindingSource but not interface,
2nd time I do, in same cell, it works normal. When I move to another
cell and repeat selecting, problem occurs again
When running my/your sample, you will notice that if you
CheckBoxClick, or CellClick, or KeyDown on row has value 1001, value
cell "Select" from row 1002 to 1009 will update, but not row 1001;
repeat again and it working
Regards
