If i can get the current index of layer A, I think I add one to the int to move layer B directly beneath it.
I need to get layer A's index in the Contents pane.
Help is appreciated.
Hi Mike
Here is some code snippet that recursively checks through all the layers (including group layers) to move the layer.
In this example the layer I want to move is the "US Cities layer". I want to move this layer to be below US Counties layer.
Thanks
Uma

This is good enough for now. However, If the user moves layer_A inside a group layer different from that specified, its index will default to -1 and place layer_B relative to its placement in the active map and not to the unspecified group layer. Further investigating Layer.Parent to identify the unspecified group layer in this scenario.
Thanks, Uma.
Uma,
I'm feeling pretty good about this approach. I was able to implement your footprint into my add-in tool.
I really appreciate your help.
