Deleting nodes programmatically
Hi all,

I'm deleting a node in my codefile (Umbraco 4.7.1) with the following code
```
Dim documentNode As New Document(Node.Id)
documentNode.delete(True)
```
If I after this point execute the code
```
New Document(Node.Id); -- throws an exception - No Node exists with id 'xxx'
```
This is what I expected because I deleted the node, but if I use
```
New umbraco.NodeFactory.Node(Node.Id); -- returns the node (that I just deleted)
```
This is not what I hoped for. Do I have to update the cache in anyway? I only know the statement
```
umbraco.library.UpdateDocumentCache(Node.Id) 
```
to update the cache, but this node.id does not exist any longer.

I hope someone has an answer,

Jeffrey

Hi Jeffrey,

Yes, you'll need to update the cache after you delete the document.

You can store the node's ID in a variable before you delete it, then use that variable when calling UpdateDocumentCache(). If that doesn't work you can try using the node's parent ID, ex:
```
int parentId = documentNode.ParentId;
documentNode.delete(True);
umbraco.library.UpdateDocumentCache(parentId);
```
HTH,
Tom

You might also need to add a call to umbraco.library.RefreshContent() if the above doesn't do the trick.

Hi Tom,

thanks for your replies. The umbraco.library.RefreshContent() seems to be necessary and now it works

Thanks a lot!

Jeffrey
