Describe the bug
A radzen DataGrid who's template type is one that overrides Equals and GetHashCode will throw a KeyNotFound exception when trying to add a new object to the datagrid

To Reproduce
Steps to reproduce the behavior:

Create Class that an int public property.
override the equals and gethashcode methods
create datagrid following example on demo site
in the edit template, the radzen numeric should bind-value to the int property
attempt to insert new value. ensure you change the value of the int property to anything other than default (0)
try to save the new object
See error

example source posted in the community at: https://forum.radzen.com/t/radzen-datagrid-and-overridden-equals-hashcode/17663

Expected behavior
I should be able to override the GetHashCode method and be able to use same object in a radzen data grid

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

OS: Windows
Browser: Edge
Version: 4.32.8

Additional context
removing the GetHashCode and the Equals method overrides from my class solves the issue, but this isn't a satisfactory work around as i need to use override the Equals method, which also calls for override the GetHashCode method.
