InvalidCastException is thrown when binding PropertyGrid.Item to collection. The exception is thrown in \\Core\Data\Extensions\FuncExtensions.cs. 

Unable to cast object of type 'System.Collections.Generic.List`1[System.Windows.Window]' to type 'Telerik.Windows.Controls.Data.PropertyGrid.PropertySet'.

Resolved with LIB version 2014.1.317

 SelectedPropertyDefinitions are not cleared when RadPropertyGrid.Item being changed.

 

This issue has been reopen as the fix for it turned out to cause other problems. 

Should be resolved with lib version 2014.3.1124.

Nested properties are not loaded when the ComponenetType does not match the DeclarationType. The same setup is correctly presented when using the UI for WinForms' PropertyGrid.

If you have a data validation, and there is an invalid field with the red border around it, if you hide this field via the filtering feature or the collapsing its group, the validation red border (and the tooltip) disappears.

To resolve this, you will need to update the ErrorTemplate of the input field (the TextBox). You can do this in the FieldLoaded event handler.

Available in the 2017 R2 Release.

RadPropertyGrid exposes PropertySetsValidationFunc property that validates the new value of a property. However, it is executed after the property is set. PropertyGrid should validate them before the setter is invoked.
