asp.net - How can I identify which controls are updated in UpdatePanel? -

-

I have a UserControl (UC) that is in an UpdatePanel. When I UC loads, I am in this UC Run a recursive method to set tooltips for all buttons, link buttons, and dropdown lists. Sometimes the problem is that I update 1 control in UC as just a dropdown list, but I have to call the recursive method on all the controls of the UC. I was wondering if there is a way to know which controls are updated in UpdatePanel, I can update these controls properly.

Thank you very soon!

Many thanks.

You can increase every control, essentially have a custom control for each control, and The property is called, for example, IsDirty.

During the event of change of control, you can set this property to right, then set tooltips can run through your method, and all the controls of IsDirty property are incorrectly reset from the wrong After completion of your processing.

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).
