You can make it a region by:

#Region "Here is an if statement"

' some code here

#End Region

Keep your '+' & '-' as image button in your application. On clicks events of that expand-collapse it using the code similar to what you wrote here.

UPDATE: That was for your UI in application. After reading another answer given, looks like it fits more to what you are asking. Use #Regions to collapse and expand.

Thanks all Support
#Region can't use any code block
it use only to function or sub
example
#Region "My Function"
public Function Myfunction()
end function
#End region
it OK but now I use to my block code ( for or if or while)
ex:
#region "My If block"
if Test=1 then
end if
#end region
it will return error
Can you tell me how to use it
Thanks !

Solution 4

It seems that it's only possible with C# but not with VB.NET :sigh:
