Determine if another document has child nodes
How would I used NodeChildNodesCount to count the nodes of another document?

I need to change the visibility of a web part based on whether or not another document has children.

Hello Jerreck,

You can access all the documents via the Documents collection.
Example for the document "News":
Documents.WHERE("DocumentName='News'")[0].NodeChildNodesCount

RE:Determine if another document has child nodes
Awesome, thank you :)

So if I also wanted to access the NodeID from the CMS_Tree table for a given DocumentID from the CMS_Document table, could I just use:

Documents.WHERE("NodeID=00000")[0].NodeChildNodesCount


Also, what is the 0 in the square brackets for? Is it expecting an argument?

Hello,

The zero is just index number - it indicates the first position in given collection.
