Hide property in PropertyGrid

[Guest]

I have a situation where I want to show a property when one object is selected in a PropertyGrid, but I want to hide that property when more than one object is selected. For example, lets say I have an object with a Name property that must be unique. If one of these objects is selected by a PropertyGrid, then I want to show the Name property in the PropertyGrid so the user can change the object's name. But, if more than one of these objects are selected, then I don't want to show the Name property in the PropertyGrid because setting the value would set all of the selected objects' names to the same value which is not allowed

Any ideas

Thank you
Lance

Hi Lance,

You may take a look at the System.ComponentModel.MergablePropertyAttribute
class,
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/
frlrfsystemcomponentmodelmergablepropertyattributeclasstopic.asp

As the docuement describes propertyies marked with MergableProperty(false)
must be displayed seperately, the default value for properties is true.

Does it resolve your problem?
