Easy GIS .NET Web Edition


I am using the EGIS.Web.Controls.SFMap control, but when the page loads in a web-browser I receive a "no map found" error message. What is the problem?

- This problem ocurrs if you forget to add a reference in the web.config <httpHandlers> section for the map control.

<httpHandlers>
    <add path="egismap.axd" verb="*"
    type="EGIS.Web.Controls.SFMapImageProvider,
    EGIS.Web.Controls, Culture=neutral,
    PublicKeyToken=05b98c869b5ffe6a"
    validate="true" />
    <add path="egismaptiled.axd" verb="*"
    type="EGIS.Web.Controls.TiledSFMapImageProvider,
    EGIS.Web.Controls, Culture=neutral,
    PublicKeyToken=05b98c869b5ffe6a" validate="true"/>
</httpHandlers>
