Hi,

I have a DataGridView on my form which is binded to a collection of custom
business objects. The collection inherits from BindingList<T>. The objects
implement INotifyPropertyChanged for updating the DataGridView when the
object properties change. I also have a custom column which hosts a custom
control that is used to edit the cells in the bound objects.  The custom
column also overrides the pain method which enables me to paint the cell the
way I need (change the background of the cell for 0.5 secs whenever a certain
property in the bound object changes)

Everything works fine initially, but the application eats up memory all the
time and it does not release it, and after 5-6 hours it becomes almost
unusable.

Has anyone expirience anything like this and if yes is there a solution.

Thanks in Advance
