How to programatically update the dynamic layer name in TOC

[RickeyTom]

This is probably been asked before, but using the search criteria of TOC update label (and others), did not
reveal the answer for me.

When creating a dynamic layer, and adding it to the map, the initial name is "Dynamic Layer".

After initialization or loading of data, I get the real name so I rename that layer programmatically.

However, the name is not updated in the TOC. It is not a repainting issue since I can force a repaint and the new
name does not appear.

When I look at the layer properties, the Layer Name is correct, but not the label on the TOC. When apply is clicked,
the TOC label is updated correctly.

How can I programmatically update the layer name in the TOC

Are you calling IMxDocument.UpdateContents after changing the layer name?

That worked.

Thanks a lot.
