Hi,

I've created feature layer from featureservice. I've almost 73 predefined edit templates and want to add couple of attributes to each template after layer is getting added on map.

I got all templates using below code but not sure how to get predefined attributes and set values.

 

  IEnumerable<FeatureLayer> featLayers = theMap.GetLayersAsFlattenedList().OfType<FeatureLayer>();

foreach (FeatureLayer item in featLayers)
{
   foreach (var template in MappingExtensions.GetTemplates(item))
    {
      //Define attribute for each template.
    }
}

Any help would be appreciated.

This works for me:

private async Task UpdateTemplates(FeatureLayer fLayer)
{
    // set the default value for the DisplayName field 
    // to whatever the name of the template is
    await QueuedTask.Run(() =>
    {
        var layerDef = fLayer.GetDefinition() as CIMFeatureLayer;
        var featTemplates = layerDef.FeatureTemplates?.ToList();
        if (featTemplates == null)
            featTemplates = new List<CIMEditingTemplate>();

        foreach (var t in featTemplates.OfType<CIMFeatureTemplate>())
        {
            if (t.DefaultValues == null)
                t.DefaultValues = new Dictionary<string, object>();
            Debug.Print(t.Name);
            foreach (var kvp in t.DefaultValues)
                Debug.Print($"\t {kvp.Key} : {kvp.Value}");
            t.DefaultValues["DisplayName"] = t.Name;
        }
        layerDef.FeatureTemplates = featTemplates.ToArray();
        fLayer.SetDefinition(layerDef);
    });
}

Did you try template.GetDefinition() to and then loop through each key value pair in CIMFeatureTemplate.DefaultValues , edit the definition, then call template.SetDefinition?

I'm able to assign values for CIMFeatureTemplate but when I call SetDefinition, values are resetting again and showing empty.

Here is my code:

 

 IEnumerable<FeatureLayer> featLayers = theMap.GetLayersAsFlattenedList().OfType<FeatureLayer>();
foreach (FeatureLayer item in featLayers)
{
 foreach (var template in MappingExtensions.GetTemplates(item))
  {
   CIMFeatureTemplate featTemplate = (CIMFeatureTemplate)template.GetDefinition();
   featTemplate.DefaultValues["fieldname"] = "SomeValue"; //Values are updated
   template.SetDefinition(featTemplate); //template.Defaultvlaues are empty here
  }
}

Thank you KirkKuykendall1,

Perfectly working.. used t.Defaultvalues["FieldName"] = "SomeValue" to update attributes in collection.

Really appreciate your help,

Prashant
