If auto hide is set for a control, then it is hidden as:
dockingManager.SetDockVisibility(control, false);
and unhidden as:
dockingManager.SetDockVisibility(control, true);

a null reference exception is thrown. What are the workarounds for this?

Hi Anthony,

Thank you for using Syncfusion products.
I have created a simple sample that shows how to test the "nullReferenceException" issue.
Please refer to the below link.
http://websamples.syncfusion.com/samples/Tools.Windows/F70639/main.htm

Kindly have a look at the above sample and if still the exception exists, could you please try reproducing it in the above sample or send us reproducing steps so that we could sort out the cause of the issue and provide you a solution? Also, Could you please specify your version, so that we will provide you the exact solution?

Regards,
Subhasheela R

Here is the version information:

Version 4.102.0.999
Runtime Version v2.0.50727

Would you be able to tell me if there was a problem of the type I have described in that version?

I realize it may be fixed in the newer versions but are there any work-arounds if this really is a bug?
