您如何在Visual Studio中查看c＃控件的自动生成的设计器代码？

Question

Right now for my User Controls I right click the control in the Solution Explorer and then choose 'View Code'. Then, in the top right corner where all the class's elements are enumerated in a dropdown box, I choose the grey'd out constructor and this brings me to the auto generated .designer.cs file that I'm looking for.

I feel like this is a really round-about way of doing it and it doesn't sit well with me. Am I supposed to be doing a better job of avoiding editing these files? Are they hard to get to on purpose or did I just clearly miss something simple in Visual Studio?

Answer 1

You should quite simply be able to use the treeview of the Solution Explorer to expand the user control items and see the code-behind and designer files.

This is curious, so I wonder what kind of user control (any particular project type)?

As for avoidance of editing these auto-generated files: yes, you should be weary in doing so, and avoid it wherever possible. Your changes are going to disappear if the code is ever regenerated (not that likely for user controls, I suppose), and the developers of the tool that generated it can't vouch for it working as it should if edited.

There are times when you do want to edit these kinds of files, however. So use your own judgement to evaluate the value of doing so. I find myself dipping into the DBML designer files often enough to delete the default constructor which conflicts with my own in the partial definition, haven't found another way to do what I want. Such is the situation.

Answer 2

Editing autogenerated code is never a good idea. The reason being that the code can be generated at any time and your changes will be lost. If you really, REALLY need to edit the code, you should be doing so using partial classes. But 95% of the time you shouldn't need to edit autogenerated code in the first place. What exactly is it that you're trying to accomplish?

Answer 3

An easy way to do it: Let's say you have a Label control called Label1 .

If it is never actually used in your code, place some code that uses it somewhere in one of your methods:

private void Test() {
  Label1.Text = null;
}

Now, put your Cursor over the Label1 control and press F12 . This will take you to the definition of Label1

Hope that helps!
