Question

I am having trouble with Crystal Reports when using charts and images which use CrystalImageHandler.aspx. The image cannot display and I suspect this is due to a problem with MVC routing.

The path image path is similar to this:

src=”/CrystalImageHandler.aspx?dynamicimage=cr_tmp_image_a8301f51-26de-4869-be9f-c3c9ad9cc85e.png”

With the URL similar to this:

localhost:01234/ViewCrystalReports.aspx?id=50

The image cannot be found prumably because it’s looking in a non-existant directory. How can I change the path CrystalImageHandler.aspx is located at? I think if I were to reference from the root the problem would be solved but anything I change in Web.Config fails to work.

I should mention this is on a conventional aspx page, not a view etc

Figured it out. The routing was interfering with the CrystalImageHandler.aspx link that was being generated. Global.aspx has the following line to tell the routing engine to ignore resource files:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

but this isn’t a conventional resource file, it’s an aspx file for some reason (anyone know why?)

adding this fixed it:

  routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");
