[CLOSED] [#433] Loop through changed PropertyGridParameters
I would like to save only those new values in my gridpanel property.
Having the example bellow, I tried to check param.IsChanged property, but if one parameter of data source is changed, all parameters return this property as true, even if it was not changed.
Thanks!
