Hi Steve,
Sorry for the delay in getting back to you.
Query: Where does syncfusion store the persistence data
The data will be stored in the isolated storage in the below storage location.
<SYSTEMDRIVE>\Users\<user>\AppData\Local\IsolatedStorage
Search "SyncfusionToolsStateInfo" in this loaction and delete all the files, which will clear the serialized data of DockingManager layout stored in Isolated storage for all applications
You can also avoid loading from isolated storage, by avoiding the LoadDockState method. So that docking manager loads in the default layout.
Could you please check and share the following details
1. Have you upgraded the syncfusion version? . If yes , is this issue occurs after upgrading the
syncfusion version?
2. Check whether the referenced assemblies are in the same version
Can we have a meeting if the issue occurs after clearing the serialized data from the isolated storage location?
Regards,
Gokul T.
