Yes it worked very well!

But in my case requirement was satisfied with simple manipulating SummaryDisplayArea property:

FieldSettings.SummaryDisplayArea = SummaryDisplayAreas.None

Thank you very much for your help!

Hello,

Did this approach work for you?  Please let me know if you have further questions.

Thanks,

Before attempting a custom dependency property, I just want to check with you whether a more simplistic approach might work; namely to store the collection of SummaryDefinitions in a variable so it can be cleared from and restored to the FieldLayout as needed.

The attached sample demonstrates this approach.  It works in this simple case with a single FieldLayout. 

if (xamDataGrid1.FieldLayouts[0].SummaryDefinitions.Count > 0)
      {
          this.xamDataGrid1.FieldLayouts[0].SummaryDefinitions.Clear();
       }
      else
       {
            foreach (SummaryDefinition def in SummColl)
            {
               this.xamDataGrid1.FieldLayouts[0].SummaryDefinitions.Add(def);
             }
        }

Hello,

I am not sure if you can create a custom DependencyProperty for the SummaryDefinitions property in order to bind to it....or if that indeed is the best route to pursue.  I will research this further and reply back here in the next couple of days when I have more information.

Thanks,

Hello cero,

Thank you for clarifying the situation.  I have forwarded your post on to Developer Support.  They should be able to provide you with the requested information.
