Hi,
I have read on many posts about the error message that it is there because we try to write to a collection when it is in ReadOnly mode.
In my case I am setting a property and after that using PropertyHasChanged(string item) method
where the error comes.
The class in which we have used the validation is inheritted from BusinessBAse.
I would like to know where is the best place to set ReadOnlyP propert to False and
which method shoul I implement and if you can let me know how.
I would appreciate,
Thanks in advance.
