  Hi

  We are facing a very “big” problem with C1DbNavigator and memory leak.
  
  The problem is that the GC does not clean up all GDI objects after closing the Form that contains the C1DbNavigator control.

  Here you have an attached example with two forms.
  
  C1DbNavigator MemoryLeak.zip

  The first form (start-up) has a button that starts the second form (with Using statement and ShowDialog) in which there is a C1DbNavigator control.
  
  After closing the second form GDI objects remain in the Task Manager.

  Here is an example.

  1. Start of the application
     
     
  2. First time start of the form with C1DBNavigator
     
     
  3. First time to close the form with C1DBNavigator
     
     
  4. Second time to start the form with C1DBNavigator
     
     
  5. Second time to close the form with C1DBNavigator
     
     

  Do you have any suggestions on this topic?

  Thanks in advance.

  Hi,

  I see that this issue is solved in v3 version only for .NET version
  
  NuGet → C1.Win.Input.DbNavigator → version 8.0.20233.636
  
  But not in the:
  
  NuGet → C1.Win.C1Input.C1DbNavigator → version 4.8.20233.636

  Is it possible in the future to solve this issue also in the Framework versions.

  Best regards.
