Hi, I'm trying to update the layers of a map by running the ApplySymbologyFromLayer GeoProcessing tool through some .NET code. For a while, there was a reported BUG-000106281 about this, but it is apparently fixed in 2.3. But.....I still cannot get it to work. Is there something wrong with my code? All of my .lyr files are located on a network drive. I get a NULL Reference Exception at the .ExecuteToolAsync line. Thanks, Map map = MapView . Active . Map ; pBar . Minimum = 0 ; pBar . Maximum = map . Layers . Count ; this . Cursor = Cursors . Wait ; GPExecuteToolFlags flags = GPExecuteToolFlags . GPThread ; foreach ( Layer layer in map . GetLayersAsFlattenedList ( ) . OfType FeatureLayer > ( ) ) { var gpresult = await Geoprocessing . ExecuteToolAsync ( "ApplySymbologyFromLayer_management" , new string [ ] { layer . Name . ToString ( ) , @"K:\DSM Shared\ArcMap Symbology\10.2 Schema\Editing Symbols\" + layer.Name.ToString() + " . lyr" } , null , null , flags ) ; pBar . Value = pBar . Value + 1 ; }

Hi Brian Pro 2.4 allows you to apply symbology from a layer file using the Pro .NET API. A new LayerDocument class at 2.4 provides this functionality. Pro 2.4 will be released this week. Using Pro 2.4, the snippet below will apply symbology from a lyr file to a feature layer in the TOC. private static async Task ModifyLayerSymbologyFromLyrFileAsync ( IEnumerable FeatureLayer > featureLayers , string layerFile ) { await QueuedTask . Run ( ( ) = > { foreach ( var featureLayer in featureLayers ) { //Get the Layer Document from the lyrx file var lyrDocFromLyrxFile = new LayerDocument ( layerFile ) ; var cimLyrDoc = lyrDocFromLyrxFile . GetCIMLayerDocument ( ) ; //Get the renderer from the layer file //This lyr file has a unique value renderer. var rendererFromLayerFile = ( ( CIMFeatureLayer ) cimLyrDoc . LayerDefinitions [ 0 ] ) . Renderer as CIMUniqueValueRenderer ; //Apply the renderer to the feature layer featureLayer ? . SetRenderer ( rendererFromLayerFile ) ; } } ) ; } Thanks Uma

Ah, ok. I see. I guess I will need to check the lyrx file first to determine what renderer to use and then assign the proper one to it. Obvious now that I think about it.

Thanks for the help!

GKmieliauskas

Hi Brian,

Do you use SetColorizer as in code sample of Uma? You need to use SetRenderer for CIMSimpleRenderer. I had the same problem.

UmaHarano

Hi Brian

The Lyrx file you attached has a CIMSimpleRenderer. Just to confirm - when you get the renderer from your LayerDefinition, are you casting it to CIMSimpleRenderer?

The code snippet above was using UniqueValueRenderer.

Thanks

Hi Uma Harano‌,

Sorry to come back to this, but I'm running across a weird issue where a newly created layer file will not work with the code you provided from last summer. This is the first time I've come across this, and not really sure what might be going on.

The code does still update for the .lyrx that have always been there, but will not work for this new one I just created (Watermain_Breaks.lyrx). I've attached a sample of it. Is there anything in it that might be causing issues??

Thanks,

GISWRKS1.WORKS.Watermain_Breaks.lyrx.zip

GKmieliauskas

Hi Uma,

I attached data for testing

ApplySymbology.zip

UmaHarano

Yes, please do send it - I can check it out to see what is happening.

Thanks

Uma

GKmieliauskas

Hi Uma,

I have tried your snippet on grid rasters.

I can send you grid and lyrx if you need.

I see the same issue with the old lyr file - I have informed the developer about this. I will let you know when this gets addressed.

With lyrx files, I was able to apply the symbology with the "Classify" colorizer - I did not load the lyrx file. Can you please explain the issues you are having?

Thanks

Uma

GKmieliauskas

Hi Uma,

Thanks for reply.

Your snippet doesn’t work with old lyr files (crashes with HResult=0x80004005 Message=Could not determine encoding).

It does not work with “Classify“ colorizer in lyrx file too.

The only way what works is loading lyr(x) file and updating data source. But there are other problems with locking as I mentioned earlier.

Here is a code snippet for using this pattern with Raster layers. Raster use the Colorizer - Get/SetColorizer.

Hi Uma,

What about the same functionality for raster layers? I have installed 2.4 and found that RasterLayer does not have SetRenderer method.

My workarounds some how lock my data and I can't run calculations on the same database on ArcMap.

The place that locks my database is creating raster layer with symbology.

Uma Harano‌,

You are your team at esri are genius'!! This works really well and is way faster than using the GP tool Thanks so much for the sample code. I only had to make a slight modification to it, and it works perfectly.

Sounds good. I will keep an eye out for the 2.4 update. Thanks for letting me know. I've been working with Nobbir to get the GP Tool code to work, but I'll check out this new class once it's available.

Hi Brian

Pro 2.4 allows you to apply symbology from a layer file using the Pro .NET API. A new LayerDocument class at 2.4 provides this functionality.

Pro 2.4 will be released this week. Using Pro 2.4, the snippet below will apply symbology from a lyr file to a feature layer in the TOC.

Hi Nobbir Ahmed‌,

Another thing I am noticing is that when the symbology does take, it doesn't always show up right. After manually doing some testing, it seems like it's the optionsal "Update Symbology Ranges by Data" field that needs to be modified to "MAINTAIN" in order for the symbology to show up properly.

I've added it to my Value Array, but when doing that it still only works once in a while.

<SPAN class="keyword token">var</SPAN> mva <SPAN class="operator token">=</SPAN> Geoprocessing<SPAN class="punctuation token">.</SPAN><SPAN class="token function">MakeValueArray</SPAN><SPAN class="punctuation token">(</SPAN>layer<SPAN class="punctuation token">.</SPAN>Name<SPAN class="punctuation token">.</SPAN><SPAN class="token function">ToString</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">@"K:\DSM Shared\ArcMap Symbology\TEST\Editing Symbols\" + layer.Name.ToString() + "</SPAN><SPAN class="punctuation token">.</SPAN>lyrx<SPAN class="string token">", null, "</SPAN>MAINTAIN"<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

Not sure if that helps or just makes things more confusing.

Is there another way to accomplish updating the symbology without using the GP Tool?? In my ArcObjects code for ArcMap I do this same thing using the following code. Is there an equivalent method to this I should look at??

Do Until pLayer Is Nothing 'loop through all the layers
                
                'create an object to refence GxLayer, an ArcCatalog layer
                Dim gxLayer As IGxLayer = New GxLayerClass
                Dim gxFile As IGxFile = CType(gxLayer, IGxFile)

                If btnMapBooks.Checked = True Then
                    gxFile.Path = "K:\DSM Shared\ArcMap Symbology\10.2 Schema\Mapbook Symbols\" & pLayer.Name & ".lyr"
                ElseIf btnEditing.Checked = True Then
                    gxFile.Path = "K:\DSM Shared\ArcMap Symbology\10.2 Schema\Editing Symbols\" & pLayer.Name & ".lyr"
                ElseIf btnVLS.Checked = True Then
                    gxFile.Path = "K:\DSM Shared\ArcMap Symbology\10.2 Schema\VLS_Layers\" & pLayer.Name & ".lyr"
                End If


                If Dir$(gxFile.Path) <> "" Then
                    'if the .lyr file exists continue, else skip
                    Dim pGeoLayer As IGeoFeatureLayer
                    pGeoLayer = gxLayer.Layer
                    Dim pAnnoLayerPropsColl As IAnnotateLayerPropertiesCollection
                    pAnnoLayerPropsColl = pGeoLayer.AnnotationProperties

                    pLayer.Renderer = pGeoLayer.Renderer
                End If

                bCanceled = Not pTC.Continue

                'show a message box if the user hits ESC
                If bCanceled Then
                    MsgBox("Operation Cancelled.  Some layers may have been changed.", MsgBoxStyle.Critical, "User Interrupt")
                    Me.Cursor = Windows.Forms.Cursors.Arrow
                    Me.Close()
                    Exit Sub
                End If

                'go to the next layer
                pLayer = pEnumLayer.Next

                'increase the Progress Bar after each layer is processed
                pBar.Value = pBar.Value + 1

Hi Gintautas Kmieliauskas‌,

Yes, I remember seeing that before, but removing and re-adding layers doesn't seem like a solution. More of a work-around to fix something that isn't working.

Sean Jones‌: Is there a bug with ApplySymbologyFromLayer in .NET?? I just want to figure out what I need to do moving forward.

Thanks,

GKmieliauskas

Hi Brian,

I have had refreshing problems with symbolizing when using more complicated symbolization (symbol rotation, few different fields and etc.)

Have you tried refresh unsuccessful symbolized layers from layer property in TOC?

1. In opened layer properties select Cache page.

2. In Cache page press "Clear Cache".

3. After that choose "Don't cache any data locally". Press OK.

If it helps then you need to change your way and do not use ApplySymbologyFromLayer_management.

1. Remove existing layer

2. Create layer from lyr file

3. Update data source to removed layer path.

4.Clear cache

It sounds strange but I use that workaround from the beginning.

Hi Gintautas Kmieliauskas‌,

Great, thanks! Things are working even better now. I can apply symbology through the code now, but it only works some of the time. If I only have one layer in my map, it works. But with multiple layers I run into problems. See example screenshots below, and the code is at the very bottom.

1. I add layers. They get the default symbology.

2. I want to apply custom symbology, so I click on my "Map Symbology" tool, pick a symbology ("Edit" in this case), and then click 'Symbolize'. The code runs, but only some of the layers get symbolized.

3. Only 2 of the 4 layers get the symbology applied. In the window I can see the name of each layer as it loops through them, and all 4 are hit, but only 2 get changed. The required 4 .lyr files are located in the network path in the code.

4. I then manually use the Apply Symbology from Layer GP Tool, to update the other layers. Basically doing the same thing that my the code should be doing. Manually it works.

Any ideas as to why this only works sometimes and not all the time??

Here is the code. It's a very simple loop.

Hi Brian,

Have you tried to set GPExecuteToolFlags flags = GPExecuteToolFlags.GPThread;

More info here: https://community.esri.com/thread/198403-pro-20-bug-apply-symbology-from-layer-geoprocessing-tool

BrianBulla

Hi Sean Jones‌,

That is definitely helping and now I can get through the code with no errors, but....the symbology (from the layer file) still does not get applied.

I've tested using some hard coded values. When I use the Apply Symbology tool in ArcPro and use the same layer/layer file combination, it works. But when doing it through code it doesn't. No errors.....just no results. The original symbology is still there.

I've tried with both .lyr and .lyrx files.

Any ideas??

If I didn't need to specify the GP flags i would just have the tool name and the value array like so:

mva <SPAN class="operator token">=</SPAN> Geoprocessing<SPAN class="punctuation token">.</SPAN><SPAN class="token function">MakeValueArray</SPAN><SPAN class="punctuation token">(</SPAN>tablePath<SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"Layer"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"STRING"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="keyword token">await</SPAN> Geoprocessing<SPAN class="punctuation token">.</SPAN><SPAN class="token function">ExecuteToolAsync</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="string token">"AddField_management"</SPAN><SPAN class="punctuation token">,</SPAN> mva<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Maybe somebody in the ArcGIS Pro SDK‌ space could look since the question is about the code.
