How to Bind to geometry in listbox

MattMiley — Mon, 20 Aug 2012 00:37:18 GMT

Is is possible to bind to a graphic's geometry in the xaml?

     <TextBlock  Text="Job # " FontSize="44" />                             <TextBlock  Text="{Binding Attributes[OBJECTID]}" FontSize="44" />                             <TextBlock  Text="XMax" FontSize="44" />  <!These two dont work!>                             <TextBlock  Text="{Binding Extent[XMax]}" FontSize="44" />                             <TextBlock  Text="{Binding Geography[Extent]}" FontSize="44" />

My overall goal is to have a listbox with icons of each point that are images that have image.sources of a bunch of Exported Map Images. something like this http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapServer/export?bbox=-127.8%2C15.4%2C-63.5%2C60.5&bboxSR=&layers=&layerdefs=&size=&imageSR=&format=png&transparent=false&dpi=&time=&layerTimeOptions=&f=image But obviously different for each one and each one being an image of that point. I just think data binding would be the best way to do this.

<!These two dont work!>
<TextBlock Text="{Binding Extent[XMax]}" FontSize="44" />
<TextBlock Text="{Binding Geography[Extent]}" FontSize="44" />

To get the geometry extent as text in your list box, you can use :
<TextBlock Text="{Binding Geometry.Extent}" FontSize="44" />

That being said I am not sure to understand what you need to do, so not sure that helps.
