How to add a button to Visual Studio Intellisense

Question

I would like to add a button to the top of the list of options returned by Visual Studio's IntelliSense. When the button is clicked, my custom code will be executed (which will, among other things, cause a popup to appear).

I call it 'button' because when the user click the item, I want a popup window to appear, as opposed to the normal IntelliSense action of completing the user's input.

Eg When we input a class name into the text editor, normally the static properties and static methods will appear in IntelliSense. But I want to add another item to the top of that list.

This item should appear at the top of the IntelliSense list, no matter what input/content caused IntelliSense to appear. The item will never change.

Is this possible, and if so, can you provide some direction as to how I should achieve this?

@SimonMourier not duplicate, in that thread, op wants to add an item in the intellisense list, but in my thread, I want to add a button, not a plain text. – Excoriate

Don't think it's possible using the official API, as the Completion class msdn.microsoft.com/library/… only supports text or icon info. – Litigant

@SimonMourier thanks for your reply, I have checked the document, is there any 3rd party API can achieve this? – Excoriate

Possibly with the help of Resharper. That would be a Resharper plugin. Check this out: #9134387 – Litigant

This link will provide good guidance to you... I used it when doing the same. http://editorsamples.codeplex.com/ – Invocate

If this could be done with a button, maybe it could also be done with any control. I like a colorpicker instead. – Adversative

Answer 1

1) In a C# or VB project, open a code file and put the cursor where you want to insert the code snippet.

2) Bring up the code snippet menu in one of three ways:

    Press CTRL+K, CTRL+X.

    On the Edit menu, point to IntelliSense, and then click Insert Snippet.

    Right-click the mouse and then select the Insert Snippet command on the shortcut menu.

3) Select the code snippet from the code snippet inserter and then press TAB or ENTER, or double-click the snippet.

In the IntelliSense property page, clear text box options or check box options for IntelliSense features that you do not want:

Show completion list after a character is typed
