I have just migrated from syncfusion 2.1.0.9 to 4.2, I have couple of problems in docking since migration.
mDockingManager.SetAutoHideMode( form, true );
throws an exception showing object set to null.
Also there is another problem find in attached screenshot before & after migration. There are 2 windows in summary tab. when I close the application the docksettings for the windows are saved in attached main.xml when I load it the windows are labelled same as you will be able to differentiate between screenshots before migration & after migration. Also in the similar way when the windows are pinned I have the problem as can be visible in the screenshots for pinned. Since I am saving the settings, the problem happens only when the settings are loaded. I have spent two days investigating myself but could succeed. please let me know if some changes I need to make to make it work.
Thanks,
Sachin
