Add Style Exception (Bugg ??)
posted

 hi,

 i try to add style to my CellValuePresenterStyle with C# .

But when this run :

                 foreach (var _cellTab in _tabCell)
                {
              
                    Style _styleCellPresent = _cellTab.Field.Settings.CellValuePresenterStyle;
                    Style _styleSurligne = (Style)dcPnl.FindResource("Surligne");

                    for (int i = 0; i < _styleSurligne.Setters.Count; i++)
                    {
                        _styleCellPresent.Setters.Add(_styleSurligne.Setters[i]);

                    }
                }

 

I have an exception :

InvalidOperationEception 

"PresentationFramework" 

After a 'SetterBaseCollection is in use (sealed), it can not be changed.

 

I have the Add methode to the Setters why i don't add style ? 

what is the probleme and how to circumvent the problem ?

 

thanks,

Nathalie

    This exception has nothing to do with Infragistics controls.  Once WPF Styles are in use, you cannot modify them.  If you want to programmatically create Styles, you should create them from scratch, and not try to modify existing Style objects.
