Override Tree - MNTP/DAMP Issue

General
Hi all,

I am trying to override the basetree (media) which is written out in various places in the back office (media section, image pickers etc...) and I am doing it through the ApplicationEventHandler:
```
BaseTree.BeforeTreeRender += BaseTree_BeforeTreeRender;
```
```
private void BaseTree_BeforeTreeRender(object sender, TreeEventArgs e)
        {
            //do stuff here to filter tree...
        }
```
This is all working great as expected - however the trees within the multinode tree picker and digibiz advanced media picker are not filtering - i'm guessing they are not using the basetree? Is there any way to do somethign similar for the multinode tree picker - i read somewhere DAMP uses the same method?

Thanks,

Kenny

Hi All -

Solved it - here it is, in case anyone else needs it - and so I can remember it in future! This allows you to filter all trees, showing only the nodes you want.

BaseTree.AfterTreeRender += BaseTree_AfterTreeRender;

private void BaseTree_AfterTreeRender(object sender, TreeEventArgs e)

{

var nodesToRemoveFromTree = new List<XmlTreeNode>();
var ms = ApplicationContext.Current.Services.MediaService;

foreach (var node in e.Tree.treeCollection)

{
if (node.NodeType == "media" || node.NodeType == "DigibizMediaTree")

{

var content = ms.GetById(Convert.ToInt32(node.NodeID));

if (//do your logic)

{
nodesToRemoveFromTree.Add(node);

}

}

}

foreach (var treeItem in nodesToRemoveFromTree)
{
e.Tree.Remove(treeItem);
}

}
