Hello,

I have the following errors mentioned in the deboug-output window when i run my application:

Remark: I only get this error when i run on Vista Businnes (Dutch), and I don't get it when running same on Windows XP SP3 (Dutch)...

System.Windows.Data Error: 22 : Cannot convert '32' from type 'Double' to type 'Infragistics.Windows.DataPresenter.FieldLength' for 'en-US' culture with default conversions; consider using Converter property of Binding.

I setup the binding in code (purpose is a dynamic column-with) depending on dynamic-value in model.

Remark: the solution itself works, but I was wondering why i get "errors" when running on Vista

   //Setup Binding: tmpBindingThumbnailSize
   Binding tmpBindingThumbnailSize = new Binding("ThumbnailSize");
   tmpBindingThumbnailSize.Source = this.XAML_iLibrary_Geometry_ViewModel;

   //Set binding: tmpBindingThumbnailSize
   BindingOperations.SetBinding(tmpFieldThumbnail, Infragistics.Windows.DataPresenter.Field.WidthProperty, tmpBindingThumbnailSize);

   Infragistics.Windows.DataPresenter.FieldSettings tmpFieldThumbnailSettings = null;
   tmpFieldThumbnailSettings = tmpFieldThumbnail.Settings;

   //Set binding: tmpBindingThumbnailSize

BindingOperations.SetBinding(tmpFieldThumbnailSettings, Infragistics.Windows.DataPresenter.FieldSettings.CellWidthProperty, tmpBindingThumbnailSize);

BindingOperations.SetBinding(tmpFieldThumbnailSettings, Infragistics.Windows.DataPresenter.FieldSettings.LabelWidthProperty, tmpBindingThumbnailSize);

 BindingOperations.SetBinding(tmpFieldThumbnailSettings, Infragistics.Windows.DataPresenter.FieldSettings.WidthProperty, tmpBindingThumbnailSize);
