Hi,

Just wondering is there an easier way of highlighting a particular vertex of a polygon? I need the first vertex of a polygon to be highlighted so that user knows that's the 1st index.

Do I have the only choice of having to add an additional point symbol on the first vertex to mimic a highlight? Doing this will also mean if I want to edit the polygon, my point symbol will also need to be constantly checked to "move" along with the polygon = additional checking codes.

Thanks

You may use a GraphicsLayer on top of your layer with only one graphic with MapPoint geometry that follows the polygon's first vertex.

Hi,

Thanks for the suggestion. But adding a point on the 2nd layer will also mean that when if i try to move any points of my polygon on the 1st layer during edit, I have to manually keep track of the point on the 2nd layer and manually move it right?
Wouldnt it be very troublesome?

Thanks!

Hi,

It's ok, I managed to find a workaround. I'll just display an arrow symbol to point to the 1st index whenever on mouse over the polygon.
Thanks for suggestions.
