Hi,

 

I'm not able tp deregister a customk control.

This solution http://community.k2.com/t5/K2-blackpearl/Cannot-de-register-custom-control/m-p/70494#M20215 does not work for me.

 

The designer website appears the message: "Could not load file or assembly 'LHTabControl' or one of its dependencies. The system cannot find the file specified."

 

The deregister command does not work with this message:

DeregisterControlType Failed: ControlTypeHasInstances,MyCustomControlProjectAG
System.Data.SqlClient.SqlException (0x80131904): ControlTypeHasInstances,MyCusto

any ideas?

The error contains 'ControlTypeHasInstances'; perhaps it is being used in a View/Form somewhere.  Perhaps try:


 


"If the control is already used on Views and Forms, then use the replaceWith command to deregister it as it will not be deregistered unless it is being replaced with another:


controlutil deregister -control:{controltypename} [-replaceWith:{controlName}]


controlutil deregister -assembly:{assemblyname} [-replaceWith:{controlName}]"

with something like a data label control,


 


controlutil deregister -control:LHTabControl -replaceWith:DataLabel

    Hi tin,

     

    thank you very much - the replacement of the control with a DataLabel was successful. :-)

    First I tried to replace the control withan other control of the same assembly. This did not work. But the replacement with a DataLabel was successful - thank you!!
