Apply ColorRamp from stylx file to FeatureLayer

RichardReinicke

Hello,

I`m currently in trouble with searching a StyleProjectItem for a specific ColorRamp / ColorRampStyleItem.

First I have to say, I want to ship my style-file (*.stylx) with my addin project. So I created a *.stylx file and saved it under my addin project root folder.

I`m also shipping the config.json with my project and for that I added both existing items into my VS project and set "always copy" for both files.

That all seems to work fine. I can load the style into the project and I can get it from project by style-name but when I search for ColorRamps in the style by searchString I always get null.

string stylePath = Path.Combine(JsonReader.addinAssemblyLocation(), "max_honsell_styles.stylx");

var styleLoaded = Project.Current.AddStyleAsync(stylePath);
StyleProjectItem style = Project.Current.GetItems<StyleProjectItem>().First(x => x.Name == "max_honsell_styles");

IList<ColorRampStyleItem> colorRamps = style.SearchColorRampsAsync(MY SEARCH STRING AS PART OF COLOR RAMP NAME) as IList<ColorRampStyleItem>;

I have no idea what could be wrong here. 

I also looked into the Assembly Cache, the stylx file is there! If I copy it and load it into ArcGIS pro manually, I see the colorScheme in it with the right name.

Any idea would be very appreciated.

Hi Richard

 You have to "Await" the AddStyleAsync call. When you do that, your custom style is loaded into Pro and then you can work with it.  The following code worked for me:

<SPAN class="keyword token">string</SPAN> stylePath <SPAN class="operator token">=</SPAN> Path<SPAN class="punctuation token">.</SPAN><SPAN class="token function">Combine</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="string token">@"C:\Users\user\Documents\StyleGeoNetTest\max_honsell_styles.stylx"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="keyword token">await</SPAN> Project<SPAN class="punctuation token">.</SPAN>Current<SPAN class="punctuation token">.</SPAN><SPAN class="token function">AddStyleAsync</SPAN><SPAN class="punctuation token">(</SPAN>stylePath<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>
StyleProjectItem style <SPAN class="operator token">=</SPAN> Project<SPAN class="punctuation token">.</SPAN>Current<SPAN class="punctuation token">.</SPAN>GetItems<SPAN class="operator token"><</SPAN>StyleProjectItem<SPAN class="operator token">></SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">.</SPAN><SPAN class="token function">First</SPAN><SPAN class="punctuation token">(</SPAN>x <SPAN class="operator token">=</SPAN><SPAN class="operator token">></SPAN> x<SPAN class="punctuation token">.</SPAN>Name <SPAN class="operator token">==</SPAN> <SPAN class="string token">"max_honsell_styles"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>
