DeleteChildCategory Method

Summary

Removes the first appearance of the specified category object from ChildCategories and deletes it from the local disk.

Syntax

C++

public void DeleteChildCategory( 
   IMasterFormsCategory category 
)

  
Public Sub DeleteChildCategory( _ 
   ByVal category As Leadtools.Forms.Auto.IMasterFormsCategory _ 
)

public: 
void DeleteChildCategory(  
   Leadtools.Forms.Auto.IMasterFormsCategory^ category 
)

Parameters

category
The category object to be deleted.

Remarks

The source code for this interface implementation class is available at <Install Directory>\Examples\DotNet\CS\AutoMasterFormsRepository.

The category directory will be deleted and cannot be restored. If the user wants to do different action he can inherit this class and override this method or do a custom implementation of IMasterFormsCategory. Be advised to have a back up copy of all Master Forms if this used this class, in case you have deleted the wrong Category.

There is no need to call DiskMasterFormsRepository.Refresh since the repository that this category belongs will be updated with this deletion.
