Setting a node's image on select

[Eric-Paul]

Having a treeview with images for each node, I tried changing the image for the node upon selection using the following event handler:

function onSelectNode( e )

{

    var dataItem = this.dataItem( e.node );

    dataItem.imageUrl = "someImage.png";

]

While stepping it appears that dataItem.imageUrl has been changed, however the treeview does not show the new image.
How can I get the new image to show?

Hello Eric,

Use the set method of the dataItem:

dataItem.set("imageUrl", "someImage.png");

The above code may require an upgrade to the Q1 service pack in order to function properly.

My code example:
noCustomDataItem.set("imageUrl", "/Administration/Content/images/active-true.gif");
Work!

Hello Alex,

Installed the Q1 service pack and it works like a charm.

Thanks!!
