Visual studio 2010 showing available events from c

问题:

In work and in home I have VS2010 installed. But in work I have this one cool feature. On the code behind file I have two drop downs. When I select some object in the left one lets say a testButton or Default2 (a page class), on the right one I get all available events for that object and when I select an event Visual Studio autogenerates it in my code-behind file. In my home VS I actually have does 2 drop downs but they work different. I have available objects on the right one but when I select for example the testButton it shows me the aspx page and points this button :/ Should I set sommething in the VS configuration or maybe in work I have some addon which I'm not aware of? Any ideas?

回答1:

This is not a VB-exclusive feature.

What you're looking for is called a navigation bar. In Visual Studio options, open Text Editor → C# → General, and you'll see an option called Navigation Bar. Enable it and click OK.

However, I believe this bar works a bit differently in VB and in C#. In C#, it only lists the existing classes and their methods; in VB, it will list all your controls and their events even if those don't exist yet.

Ok I think I've found the answer. It seems that this feature is only available when the current file is in VB.Net. In my opinion this suks :/

回答3:

You need to go the design view, in the Properties box, click on Events (lighting bolt) and double click on the events you want to code behind:

@shin is correct, this is a VB.NET only feature; Microsoft only had feedback reports dating back to 2004 mentioning this feature, so I have opened a new bug request with Microsoft regarding this; and also added feedback to Visual Studios account on UserVoice...

I encourage everyone who this issue effects to go and vote up & confirm this issue with them.

I dislike that C# doesn't provide such a useful time-saving function.

回答5:

It is most certainly is a VB only feature and has been reported on numerous occassions to Microsoft.

回答6:

It is possible to see all the available Events in C# & Asp.net too, but not inside code window as possible in VB. But you can see all Events of any selected Control in its Property Window. Open Properties, then Click Events.

1. Up to Visual Studio 2010, only Vb.net has this feature: on code-behind page, the code panel upper-left drop down shows a control's name, and the right drop down shows this control's available events. When clicking this event we can get the code-block for this event. This feature is not available in C#.

2. Without above feature, we can still get a control's available events for both C# and Vb.net: We must select the control on the aspx page and choose the design view at the lower left corner, then on the Properties panel click the Event button (the lighting sign), then available actions will be shown, double-click the name of the event you want, the event code will be generated in code-behind.

回答8:

This and the feature to generate event handlers without having to switch to Design view for C# is finally coming in Visual Studio 2012. It was about time.

回答9:

Even the 2012 feature is not enough. You still have to guess for Page level events (Init, PreRender, etc) and also files that haven't already been filled out for you like Global.asax, which depending on the template you started with may or may not have all the event handlers already specified.

Agreed that Event Handlers is one of the things VB has for years and years and years handled way better than C#. I can't count the number of times I've had to remind a fellow C# developer that some events do, in fact, exist.
