Partial Trust Support
Updated on Jul 3, 2025
This topic will give you an overview of the Partial Trust support across all the Telerik WPF controls.
All controls in the suite require the following permissions due to the license mechanism that is used:
-
System.Security.Permissions.FileIOPermission
-
System.Security.Permissions.SecurityPermission
-
System.Security.Permissions.ReflectionPermission
Increasing the permissions of a partially trusted application could usually be achieved by changing the permission set in the application manifest.
The below table lists all controls in Telerik UI for WPF suite and the additional permissions they require.
