[Solved] Data Error: BindingExpression path error

[Alessandro]

We are using the grid version: 2010.3.1110.1040
We are Autogenerating columns

When the grid is bound we get numerous errors along these lines:

System.Windows.Data Error: BindingExpression path error: 'Selected' property not found on '<Person[11234134]> MICKY MOUSE' 'CO.OM.Person' (HashCode=15422169). BindingExpression: Path='Selected' DataItem='<Person[362811]> AARON MURPHY
123  E 1ST ST BLANKETTOWN NY 12345' (HashCode=3031234); target element is 'Telerik.Windows.Controls.GridView.GridViewCell' (Name=''); target property is 'Value' (type 'System.Object')..

I think this is causing performance issues on the grid. Any ideas?

Hello,

 You have binding to an invalid property for some of the grid columns.

All the best,

Vlad,
 How can that be? We're auto-generating columns?
