How does BuildSiteMap() Method work?

Question

I am working on CustomSiteMapProvider that i have Derived from StaticSiteMapProvider. I have override BuildSiteMap() Method to Build Sitemap.It is working properly, But Can anyone tell me How it is works internally? I have found that It is getting called more than one time. Why is this executing more than one?

How many times does this method get executed?

I have read many artical, But I didnot find any discussion about internal working of BuildSiteMap() Or why it gets executed more than once?

Any idea? Any artical Or link will be appreciated...

Answer 1

Please read MSDN

It says

The BuildSiteMap method is called by the default implementation of the FindSiteMapNode, GetChildNodes, and GetParentNode methods.

If you override the BuildSiteMap method in a derived class, ensure that it loads site map data only once and returns on subsequent calls.

So at some point, system calls FindSiteMapNode, GetChildNodes, and GetParentNode methods. And then BuildSiteMap will be called as well.

Here is another MS engineer's post
