用于bindingExpression的Silverlight UpdateTarget()解决方案

试试这个。将imageblobmember替换为XAML控件的x:name/name,并将image.sourceproperty替换为适当的值,具体取决于控件的类型。

BindingExpression bindExp =
 ImageBlobMember.GetBindingExpression(System.Windows.Controls.Image.SourceProperty);
Binding bind = bindExp.ParentBinding;
ImageBlobMember.SetBinding(System.Windows.Controls.Image.SourceProperty, bind);
