I need to add a widget in Configurable Map Viewer (CMV), which will return me the nearest facility of parcel number entered in the box. Which is to be done by Network Analyst in ArcMap and i have created that layer.Here is the code, which actually return me the nearest facility when i click a point any where. I need to do this in a widget of CMV. Please help me regarding how can i create a widget for network analyst.
