Apply LayerX Files from Portal

Vidar

I can store a layerX file in Portal and access from my Pro Client with it's item ID:

Item testLayerLryx = ItemFactory.Instance.Create(lyrxId, ItemFactory.ItemType.PortalItem);

Great. However - can I use this object to apply symbology from the layerX entity to an existing layer already loaded into Pro. It looks tricky as the constructor only seems to accept a filepath and a CimLayerDocument.

LayerDocument layerDoc = new LayerDocument();

- but I may going down the wrong path in any case.

Also, the LayerFactory only makes layers, but I can't see anything similar for layer files.

Anyway, any help - much appreciated.

Hi Simon,

You can create a layer from an item using this overload of the CreateLayer method: 

<SPAN class="keyword token">public</SPAN> Layer <SPAN class="token function">CreateLayer</SPAN><SPAN class="punctuation token">(</SPAN> 
   Item item<SPAN class="punctuation token">,</SPAN>
   ILayerContainerEdit mapOrGroupLayer<SPAN class="punctuation token">,</SPAN>
   <SPAN class="keyword token">int</SPAN> index<SPAN class="punctuation token">,</SPAN>
   <SPAN class="keyword token">string</SPAN> layerName
<SPAN class="punctuation token">)</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

You can apply your lyrX file's symbology to a layer in the active map using code similar to the snippet below:

QueuedTask<SPAN class="punctuation token">.</SPAN><SPAN class="token function">Run</SPAN><SPAN class="punctuation token">(</SPAN> <SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="operator token">=</SPAN><SPAN class="operator token">></SPAN> <SPAN class="punctuation token">{</SPAN>
