jquery - ASP.NET MVC 4 routing corrupting a decimal json value -


i have method in controller:

    [httppost]     public virtual jsonresult add(additemmodel request)

this receives ajax call. json request sends serialized version of "additemmodel" class , mvc routing creates additemmodel expected properties (which include datatypes such strings, integers , decimals).

i deploy our qa server , behaviour different. json request identical (checked fiddler) additemmodel has properties populated except decimal 1 - has value of 0 default value.

i can't find differences between our dev environment , qa server, i'm not looking @ right thing.

can suggest causing difference?

dev win7, qa win2003 server, running latest patches.

thanks in advance

update #1

we added custom model binder both decimal , nullable decimal types , added tracing ascertain happening.

when value came in, picked attempted value:

var attvalue = modelbindingcontext.valueprovider     .getvalue(modelbindingcontext.modelname).attemptedvalue;

and converted decimal value. tested base's bindmodel(controller, context) return.

for us, when attempted value '5', our conversion gave decimal value of 5. mvc code couldn't handle - returned '' object, arrives in our controller method zero.

however, when attempted value '5.1', both our , mvc code correctly gave decimal of 5.1.

so, appears when:

  • json has value of : 5
  • mvc attempts bind poco's property datatype decimal , fails

but when:

  • json has value of : 5.1
  • mvc attempts bind poco's property datatype decimal , works

as mentioned, happens on our qa server, not in dev. suggest microsoft may have fixed this? mentioned, appears both our dev , qa environs patched.

any suggestions here?

see this answer. in short, default model binder uses .net's type converter, cannot convert integers decimals.
