Hi all,
I created a decorator for DataGridColumn that change the behavior of the InitializeCell method.

In a method that response to SortComando event I remove the columns of the DataGrid and decorate then with my decorator.

Well, my InitializeCell method works fine like I want, but I have one little problemn: if I change the state of the column then the change is lost.

Without the decorator, all changes in the columns of the DataGrid are preserved, but if I decorate the columns the changes are lost.

I look for the documentation and the BoundColumn, for example, don't override the SaveViewState, LoadViewState or TrackViewState methods from DataGridColumn Type. So, I think that this isn't the problemn. (I use the default implementation for this methods because they are protected and I can't delegate then to the decorated column).

I think that the problemn is change the DataGrid structure (I change the columns by decorated columns).

Can somebody help-me?

Thank you for pay attention,
