Hi,

    I have a Class A which implements bindinglist<B>  and ITypedList and am using it as a datasource for grid. Internally i use propertydescriptors which allows user's to add new columns dynamically to the grid.If user'  decides to rename the newly added customproperty, how can i do that? 

I am trying to implement by renaming the property in my underlying object which in turn shoud reflect in the grid when it queries property descriptor collection. It partly works when there is no data for that column and i can rename as manay times i want. But when i type some value on the column and then i try to rename the property, It throws me a runtime exception where grid can't load

"Message:   Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index

I really appreciate ur help.
