Bind a TextBlock to the Map's Resolution

Question

Does anyone know why this: produces "NaN" instead of the map's resolution? I tried the same thing with the map's Extent.Width property and it works fine.

When it becomes available, there should be a link from here: http://help.arcgis.com/en/webapi/silverlight/index.html

I think you have it correctly if your map control is named "MapMain". However, v2.1 and earlier do not support Binding for "Resolution", this is new to v2.2

Where is v2.2 available?

Thanks,
David

I think you have it correctly if your map control is named "MapMain". However, v2.1 and earlier do not support Binding for "Resolution", this is new to v2.2 The following code will only work for v2.2 and up: The following code will work for v2.1 and earlier: private void MyMap_ExtentChanged(object sender, ExtentEventArgs e) { double res = Convert.ToDouble(MyResolution.Text); if (res != (sender as Map).Resolution) { res = (sender as Map).Resolution; MyResolution.Text = res.ToString(); } }
