How can I determine the layer name in an edit session?

Question

I have a problem with an editor extension in an Add-In for ArcGIS 10. The editor extension listens on different events occuring on shapefile layers via registering listeners:

mEditEvents.OnChangeFeature += OnChangeFeature;
mEditEvents.OnCreateFeature += OnCreateFeature;
mEditEvents.OnDeleteFeature += OnDeleteFeature;

All these callbacks get are a parameter of type IObject, which can be cast to IFeature. With this IFeature I can get the feature class and its alias name (IFeature.Class.AliasName) which seems to be the name of the shapefile associated with this feature, but I want the name of the layer associated with this feature which can be different from the shapefile's name.

Is there any way how to get this layer name?

Thanks in advance!

Update:

I found a solution (see my comment below) - thanks for the help!

Answer 1

You may need to get the dataset's name from the feature first. Then you can loop all the layers in TOC and check if their dataset name matches the one obtained earlier. It would look something like below.

IFeature feature = //get the feature..;
IDataset featureDs = (IDataset)feature.Class;
IMap map = //get the map...;

for (int i = 0; i < map.LayerCount; i++)
{
    ILayer layer = map.get_Layer(i);
    if (layer is IFeatureLayer)
    {
        IFeatureClass layerFc = ((IFeatureLayer)layer).FeatureClass;
        IDataset layerDs = (IDataset)layerFc;

        if (layerDs.Name == featureDs.Name)
        {
            //print the layer name in TOC..
            System.Diagnostics.Debug.Print(layer.Name);
        }
    }
}

I finally found a simple solution: Before starting the edit session I store the alias names for each of the layers (I can identify the layers by their names).

With this mapping I now can relate any single edit event to the right layer because I have the AliasName of the feature's FeatureClass.

IFeature:Table

[IDataset:Name

You can use the IFeature:Table property. Table implements IDataset so you can get the name from the IDataset:Name property. Here is an example:

Private Function GetPathFromFeature(ByVal pfeature As IFeature) As System.String

If pfeature Is Nothing Then Return Nothing

Dim ptable As ITable = CType(pfeature.Table, ITable)

If ptable Is Nothing OrElse Not (TypeOf ptable Is IDataset) Then
    Return Nothing
End If

Dim dataset As IDataset = CType(ptable, IDataset) ' Explicit Cast

Return (dataset.Workspace.PathName & "\" & dataset.Name)

End Function
