Filter out list of code snippets visible on the list view

Question

Following this link I have a set of code snippets.

But the snippet insertion has to be w.r.t the context, viz. if I do 'Insert Snippet' before declaring a class, it shouldn't show 'method declaration' snippet. Also required is to filter snippets as per managed or unmanaged code.

In short I am looking for a mechanism as follows:

if <condition>
{
 modify list of snippets visible in the menu
}

Do we have such a mechanism or something similar? Ideas welcome.

I found a solution to my question. Hope it helps someone.

I followed the instructions on the links: Video on Code Snippets & Code Element

Got the snippet.xml file to contain the following:

<Code Language="Language"
    Kind="method decl">
        Code to insert
</Code>

Then called the expansionProvider.DisplayExpansionBrowser in the FilterView class (refer to the video):

string[] kind = new string[1];                            
kind[0] = "method decl";
return expansionProvider.DisplayExpansionBrowser(TextView, 
                                                 snippets, 
                                                 null, false, kind, false);

Thus the specific snippet will appear in 'method declaration' context. Thus other snippets can be done. The xml has to hold the context information.
