C# 클래스 Rock.Web.UI.Controls.GeoPicker

This control will create a Google map with drawring tools that allows the user to define a single point or a polygon which forms a geo-fence depending on the Rock.Web.UI.Controls.GeoPicker.ManagerDrawingMode.Point. To use on a page or usercontrol: ]]> To set an initial value: gpGeoPoint.SetValue( DbGeography.FromText("POINT(-122.335197 47.646711)") ); To access the value after it's been set use the SelectedValue property: DbGeography point = gpGeoPoint.SelectedValue; If you wish to set an appropriate, initial center point you can use the CenterPoint property.

메소드	설명
ConvertPolyToWellKnownText ( string latCommaLongPipe ) : string	Convert string from "lat1,long1\|lat2,long2\|..." to Well Known Text (WKT) http://en.wikipedia.org/wiki/Well-known_text format "POLYGON(( long1 lat1, long2 lat2, ...))". It is expected that the input is a single polygon (not a polygon with an inner polygon). It will also correct the orientation (clockwise-ness) of the points because DbGeography needs them to be in counter-clockwise order.
GeoPicker ( ) : System	Initializes a new instance of the GeoPicker class.
IsClockwisePolygon ( PointF polygon ) : bool	Attempt to determine if the polygon is clockwise or counter-clockwise. Thank you dominoc! http://dominoc925.blogspot.com/2012/03/c-code-to-determine-if-polygon-vertices.html
RenderBaseControl ( System.Web.UI.HtmlTextWriter writer ) : void	Renders the base control.
RenderControl ( System.Web.UI.HtmlTextWriter writer ) : void	Outputs server control content to a provided T:System.Web.UI.HtmlTextWriter object and stores tracing information about the control if tracing is enabled.
SetValue ( System.Data.Entity.Spatial.DbGeography dbGeography ) : void	Sets the value. Necessary to preload the geo fence or geo point.
