Hi,

How&nbsp;do&nbsp;I&nbsp;add&nbsp;feature&nbsp;to&nbsp;FeatureLayer&nbsp;from&nbsp;another&nbsp;FeatureLayer&nbsp;with&nbsp;all&nbsp;column&nbsp;values?  
  
I&nbsp;try&nbsp;like&nbsp;this:

`//Works, but seems that doesn't add column valuesmyLayer.FeatureSource.AddFeature(feature);//Doesn't work like this at all (invalid arguments). What should be the second variable?myLayer.FeatureSource.AddFeature(feature, feature.ColumnValues);`

</div>

I&nbsp;find&nbsp;out&nbsp;that&nbsp;I&nbsp;needed&nbsp;to&nbsp;add&nbsp;all&nbsp;columns&nbsp;manually&nbsp;like&nbsp;this:

&nbsp;

`myLayer.Open();oldLayer.Open();Collection<FeatureSourceColumn> fsc = oldLayer.QueryTools.GetColumns();foreach(FeatureSourceColumn fsctmp in fsc)	myLayer.Columns.Add(fsctmp);oldLayer.Close();myLayer.Close();`
