In the OnChangeFeature event is there a way to determine which field was just edited causing the event to fire? I'm doing several tasks in OnChangeFeature that only need to happen when certain fields are edited, so being able to determine which field just changed would be helpful. Any suggestions?

5Did you try IRowChanges and loop through each field to see if ValueChanged is true?– Kirk KuykendallCommented Jul 8, 2011 at 17:39

That is the way to go. I was going to answer but Kirk is like Skeet from SO. :P.– George SilvaCommented Jul 8, 2011 at 18:13

Not sure why everyone is commenting instead of answering but here's an example with both an IRowChanges and an IFeatureChanges (in case you are interested in the geometry). I did have to strip out some lines of code, but this should be close:
IRowChanges: http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#//0025000007vw000000
IRowChanges rowChanges = obj as IRowChanges;
for (int i = 0; i < obj.Fields.FieldCount; i++)
{
if (rowChanges.ValueChanged[i])
{
object oldValue = rowChanges.get_OriginalValue(i);
object newValue = obj.get_Value(i);
}
}
}
IFeatureChanges: http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#//0025000002qp000000
IFeatureChanges featureChanges = obj as IFeatureChanges;
if (featureChanges != null && featureChanges.ShapeChanged)
{
// Do something
// featureChanges.OriginalShape
}

1You can use IRow for the geometry field as well. All you have to do is to pass up the index of the geometry field. Commented Jul 8, 2011 at 19:01

IRowChanges is exactly what I was looking for. I'd give Kirk answer points as well if I could. Thanks to all. Commented Jul 8, 2011 at 20:23
