I'm having a problem with the RadPropertyGrid when bound to an indexed property. Getting the property works fine, but after changing the field, the setter never gets called.

 Attached is a simple test program. This program has a RadPropertyGrid bound to a simple string property and an indexed property. These same two properties are also bound to a TextBox.

 Notice that when the values in the TextBoxes are changed, the debug output shows that the setters are called and the values displayed in the RadPropertyGrid are properly updated.

 When the simple string is changed in the RadPropertyGrid, the debug output shows that the setter is called and the value displayed in the TextBox is properly updated.

 But, when the indexed property is changed in the RadPropertyGrid, the debug output does not show the setter getting called and the value displayed in the TextBox does not get updated.

*** The support for collection indexer binding will be available with R2 2016.

Provide support for Editor Attribute.

Three separate modes for RadPropertyGrid's ordering according to its states. OrderIndex should be respected in Sorted state/Grouped state/Both states (default value).

RadPropertyGrid's Description Panel Resizing/Visual Studio like behavior

Expose an event  corresponding to AutogeneratingPropertyDefinition so that the user can customize the property definitions.

Research the opportunity to add support for TypeConverter on class.

Available in the 2017 R1 Release (2017.1.117).

Currently, if you change the value of a property in the object bound to the property grid control, the control's UI won't reflect this change.

So far only IDataErrorInfo and exception based validation is supported. RadGridView already supports INotifyDataErrorInfo, it's time for RadPropertyGrid.

Currently, the control allows you to search only for fields that have been expanded already. If a parent field was never expanded, the search won't look for its children.

Allow searching in not expanded fields.

Available in the 2017 R1 Release (2017.1.117).

Behind the scene we need to update any changes made in the property grid, in a SQL Server database, too. With our current implementation we fire a database request if a property is edited in the property grid. This is fine if only one entity has been selected. If more than one entity has been selected (ProperytSetMode “Intersection”) a database request is fired for each entity if a property is edited. This is not very performant for us.
We need an event like “EditEnded” to figure out when the PropertySetViewModel has updated all ViewModels. Then we are able to updated the necessary changes in the database in a single call. 

It should be a themable editor which allows users to select a file or a directory from the file system using OpenFileDialog, FolderBrowserDialog or directly to type the full path to the file.

As a user I want be able to use FlagEnumEditor when RadPropertyGrid is bound to collection

An non edit mode is enabled in the control when the EditMode is set to Single. In this case, only one field can enter edit mode and the rest are read only. 

Currently, there is no API that allows you to customize the content (that shows the property value) of the read only fields.

Add an API that allows you to customize the read only content. Similar to the EditorTemplate of the PropertyDefinition.

 

Currently the AutomationID of the PropertyGridField is set to "{0}_FieldEditor", where {0} is the DisplayName of the property definition. We can introduce an option to prevent this.
