In the designer you go to the events tab for the control in question, select the event that has the unwanted handler; and delete the name of the handler. Then save the form again.

This doesn't delete the method itself I think, (possibly unless it's empty or just been added).

Update

I dare say the reason for why it nearly always doesn't delete the method is because it could be used as a handler on another control's event. After all, in the UI you only asked to remove one event's handler; not every handler bound to that method. Then there's the question of whether the back-end code is dirty (i.e. unsaved) - checking whether the method is empty or not isn't reliable in that case. Yes, all of these could be worked around, but having to delete the method manually isn't exactly a hardship :) and at least this way VS doesn't end up deleting methods you actually want to keep.

Look at the properties window when you select the Control. Click on the little flash and you'll see the Events listed, along with your event (Click or whatever), and your event will have the name of the assigned method behind it. Just delete that method. 

That deletes the method, only if it's empty and otherwise unused though, which is quite reasonable. After all you might have put a lot of work into that event handler. (note: Just tried it again and apparently it doesn't always delete empty methods even though it did a few minutes ago. weird.)

blocks|key|2441179|text|您应该再次使用events网格并右键单击插入的事件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2441180|选择“重置”菜单选项。这将删除在InitializeComponent中分配的事件处理程序和代码设计器中的emtpy事件的代码。|offset|length|style|BOLD|2441181|注意，如果在事件中添加代码，不会删除新代码。|2441182|entityMap^0|0|1H|5|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

You should use again the events grid and right click on the event you have inserted. 
Select the Reset Menu option. This will remove the event handler assigned in the InitializeComponent and the code of the emtpy event in the code designer.

Note, that if you add code at the event, Visual Studio doesn't remove the new code.

Go back to the form and hit CTRL+Z.

blocks|key|1594089|text|最好的方法是通过设计器中的Properties网格。您可以单击Reset按钮或只删除文本，它将删除InitializeComponent()方法中的事件挂钩。如果您的方法在后面的代码中为空，它也会在那里删除它：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1594090|​|1594091|📷|atomic|offset|length|1594092|1594093|如果方法主体包含的代码在设计器中意外地被重置，或者如果您的方法是从代码的其他部分引用，则必须手动删除它是有意义的。Visual在谨慎方面是错误的。|1594094|如果首先删除方法主体，那么它不删除对它的引用的原因可能在一定程度上与剪切和粘贴代码有关。如果您想将该方法移到代码中的不同位置，则裁剪它的操作将切断对它的引用。在你贴上它之后，你会想知道为什么你的活动不再被称为。同样，请注意错误，因为对于开发人员来说，追踪无关代码并不那么困难。|1594095|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://developer.qcloudimg.com/http-save/yehe-900000/2c1959eb4a80967eccff2222de00d7fb.jpg|imageAlt^0|0|0|0|1|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Y|8|@]|9|@$G|Z|H|10|1|11]]|A|$]]|$1|I|3|C|5|6|7|12|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|13|8|@]|9|@]|A|$]]|$1|L|3|M|5|6|7|14|8|@]|9|@]|A|$]]|$1|N|3|-4|5|6|7|15|8|@]|9|@]|A|$]]]|O|$P|$5|Q|R|S|A|$T|U|V|-4]]]]

The best way to do this is through the Properties grid in the Designer. You can click the Reset button or just delete the text and it will remove the event hook-up in the InitializeComponent() method. If your method is empty in your code behind, it will also delete it there:

<img src="https://i.stack.imgur.com/2g8HH.jpg" alt="enter image description here">

It makes sense that you would have to manually delete the method body if it contains code in case it accidentally got Reset in the designer or if your method is referenced from some other part of your code. Visual Studio is gong to err on the side of caution.

If you delete the method body first, the reason it is not deleting the references to it probably in part has to do with cutting-and-pasting code. If you wanted to move the method to a different place in your code, the acting of cutting it would sever the references to it. After you pasted it, then you would wonder why your event was no longer be called. Again, error on the side of caution since it's not that difficult for the developer to track down extraneous code.

This pertains to C# 2017. So hopefully it would help others.

I'm new to C# (or at least back to code it) and ran with the same issue.

I commented out the event that I did by mistake. Then in the Error list, you will find an error there because that event is missing. Double click on it. It'll take you to the Designer code that "wires" the event. Once there, find the unwanted event and comment it out/delete it. Take care!

This is a simple scenario:

I add an event to a control on the form by double clicking on its field (in Events part). But, then I decide that it was unnecessary and delete the automatically generated method. I'll run the program and it gives an error telling me that the event still exists in the <code>InitializeComponent()</code> and I must delete it from there.

So, is there anyway to avoid deleting the event "manually"? Is there anyway to fully delete it without leaving any trace (specially in <code>InitializeComponent()</code>)?

Update: Also, another question arose:

When I delete the method from the code, the method name in the event field will disappear. So, if the <code>InitializeComponent()</code> is linked to these events, why isn't it updated with the empty event field?

这是一个简单的场景：我通过双击窗体上的字段(在Events部分)将事件添加到窗体上的控件中。但是，我认为这是不必要的，并删除了自动生成的方法。我将运行这个程序，它会给出一个错误，告诉我这个事件仍然存在于InitializeComponent()中，我必须从那里删除它。那么，是否可以避免删除“手动”事件？是否可以完全删除...
