c# - Add editing to MVVM in a hierarchical data structure -

-

This question is a follow-up to one, and it is more about confirmation than the open question.

The example of my visual model is a personal example of the model, _modelInst .
During modeling, there is a unique use of visual modal on model data (hence the model does not need to implement INOTifyPropertyChanged.) <

< / P>

/ strong>
Example Simple Price Field
Back _modelInst.fieldname;
_modelInst.fieldname = value;
It is easy to implement ...

  • Create and manage a view model example on parental data structure
    Example for more complex object types like Streets :

    • Creating a new view model for that type.
      Music knows her parents and her field name.
    • Display in a ContentControl + DataTemplate
    • Receive / Setting: Through Parental Methods with Field Name as Parameters

      Overwrite Entire Original Object Only a field is changed while doing

    This means that a new interface implemented by parents for each of these structures ( _modelInst With update routines working on).

  • Create a ViewModel instance with no direct knowledge of parental data structure
    Example

    • < Li>

    sending update instructions for parents

  • Message
  • reflection (the guardian knows that Which child is called the Festival by comparing it with the example of all the stored children in the ceremony)

    • All of these are implementing a big mess, which are the areas of the model Fan for Make Shn who is editing.
    There are lots of models that mean all areas ..

    (4.) Anyone can create a normal void that works through a single reflection, where each sub-object is used by your parents and Knows its area name (+ index, if in a list).
    The argument of the root will only interfere with the model.
    But that solution will also require an instrument to store the path of a field within _modelInst . .

    Is there any other (more simple) way to achieve this? Did I misunderstood the principles of MVVM? (again)?
    Is MVVM suitable for the manipulation of large hierarchical data structures?

    Hope this resource will help; They helped me a lot, as I have learned about how to represent the object graph / hierarchy with the MVVM and the visual model:

    Obfuscating Python code? -

    -
    I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
