Graphics layer: element placement

helenchu

Hi

I'm trying to have an element placed at the bottom left corner of the selected feature but can't figure out how to do it.  I can place it at the center of the polygon fine but not at any other positions.  Your help is much appreciated.

while (foundCursor.MoveNext())
{
using (var row = foundCursor.Current)
{
var shape = row as Feature;
var poly = shape.GetShape() as Polygon;
myLabelGraphic.Shape = poly.Extent;
myLabelGraphic.Placement = Anchor.BottomLeftCorner;

}

Hi Helen,

You have almost all the logic in  

Once you get the polygon of your feature, you need to get its lower left corner coordinates. Use that for the graphic's shape property.  So like this:

<SPAN class="keyword token">var</SPAN> poly <SPAN class="operator token">=</SPAN> currentRow<SPAN class="punctuation token">.</SPAN><SPAN class="token function">GetShape</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="keyword token">as</SPAN> Polygon<SPAN class="punctuation token">;</SPAN>
<SPAN class="keyword token">var</SPAN> lowerLeftX <SPAN class="operator token">=</SPAN> poly<SPAN class="punctuation token">.</SPAN>Extent<SPAN class="punctuation token">.</SPAN>XMin<SPAN class="punctuation token">;</SPAN>
<SPAN class="keyword token">var</SPAN> lowerLeftY <SPAN class="operator token">=</SPAN> poly<SPAN class="punctuation token">.</SPAN>Extent<SPAN class="punctuation token">.</SPAN>YMin<SPAN class="punctuation token">;</SPAN>‍‍‍
myLabelGraphic<SPAN class="punctuation token">.</SPAN>Shape <SPAN class="operator token">=</SPAN> <SPAN class="comment token">//Create MapPoint using these coordinates.</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Thanks
