Hello,&nbsp;&nbsp;I&nbsp;am&nbsp;using&nbsp;the&nbsp;code&nbsp;below&nbsp;the&nbsp;line&nbsp;to&nbsp;draw&nbsp;an&nbsp;ellipse&nbsp;&nbsp;when&nbsp;the&nbsp;user&nbsp;clicks&nbsp;a&nbsp;point.&nbsp;It&nbsp;seems&nbsp;that&nbsp;using&nbsp;"ReturningColumnsType.AllColumns"&nbsp;is&nbsp;what&nbsp;is&nbsp;needed&nbsp;to&nbsp;draw&nbsp;the&nbsp;ellipse.&nbsp;&nbsp;The&nbsp;ellipse&nbsp;has&nbsp;a&nbsp;radius&nbsp;of&nbsp;10&nbsp;miles.&nbsp;&nbsp;All&nbsp;I&nbsp;am&nbsp;doing&nbsp;is&nbsp;adding&nbsp;the&nbsp;"selectedFeatures&nbsp;in&nbsp;the&nbsp;selectedFeaturesCollection&nbsp;to&nbsp;the&nbsp;new&nbsp;Collection&nbsp;efc&nbsp;and&nbsp;using&nbsp;&nbsp;GetFeaturesIntersecting(selectedExtent)&nbsp;to&nbsp;find&nbsp;itself.&nbsp;&nbsp;It&nbsp;seems&nbsp;that&nbsp;I&nbsp;should&nbsp;be&nbsp;able&nbsp;to&nbsp;do&nbsp;the&nbsp;following,&nbsp;but&nbsp;this&nbsp;doesn't&nbsp;show&nbsp;the&nbsp;ellipse.

Thanks,&nbsp;sckeels...

Hi&nbsp;Steven,&nbsp;  
&nbsp;&nbsp;  
&nbsp;Could&nbsp;you&nbsp;check&nbsp;whether&nbsp;the&nbsp;count&nbsp;of&nbsp;the&nbsp;InternalFeatures&nbsp;at&nbsp;the&nbsp;end&nbsp;of&nbsp;the&nbsp;loop&nbsp;equals&nbsp;zero?&nbsp;If&nbsp;not,&nbsp;I&nbsp;guess&nbsp;that&nbsp;you&nbsp;missed&nbsp;refreshing&nbsp;the&nbsp;Overlay&nbsp;which&nbsp;contains&nbsp;the&nbsp;highlightEllipseLayer.&nbsp;If&nbsp;it&nbsp;doesn’t&nbsp;fix&nbsp;your&nbsp;issue,&nbsp;please&nbsp;send&nbsp;us&nbsp;a&nbsp;quick&nbsp;sample.&nbsp;  
&nbsp;&nbsp;  
&nbsp;Any&nbsp;questions&nbsp;please&nbsp;let&nbsp;me&nbsp;know.&nbsp;  
&nbsp;&nbsp;  
&nbsp;Thanks,&nbsp;
