asp.net mvc - c# custom model binder for specific model and specific variable type -

I have a problem with myself in vain ints and validation text.

Actually I want to change the validation message when a null integer is not provided which is shown

from then

  "value ' Xxxxxxxxxxxxxxxxxxxx "Invalid"  

  "Please provide a valid number"  

I have a custom model the binder, such as

  public class IntModelBinder: IModelBinder {public object BindModel (controllerContext controllerContext, ModelBindingContext bindingContext) {var integerValue = bindingContext.ValueProvider.GetValue (bindingContext.ModelName); If (integer value == tap = integer value. Used value == "") empty return; Var integer = integer value. Used value; Bindingkntestkmodelstteksetmodelvlua (Bindingkntestkmodelnme, Bindingkntestkvluaproviderkjtwlua (Bindingkntestkmodelnme)); Try {return int.Parse (integer); } Catch (exception) {bindingContext.ModelState.AddModelError (bindingContext.ModelName, String.Format ( "\" {0} \ bindingContext.ModelName "is invalid, enter a valid number.")); Return tap; }}}  

At this time I have updated my global.asax.cs, so all tap inbelt uses this model binder, although I have all these tapable inputs I just do not want to use it, I just want a specific model to use it and only use my model binder on Nullible Ents in that model. Is there any way that I can tie this model bander in my model and collaborate only with faucetable variable variables?

I've tried to use his Modbandr on its models like

  [ModelBinder (typeof (IntModelBinder))] public class CreateQuoteModel {....} < / Code> 

but it does not check on inert ints, I want to avoid the third party addon

If you are returning empty on nullable ints are

  if (integerValue == null || integer value. Try the value == "") empty return made;  

So that you are not adding that error to your inability to the nullible ints.
Apart from this, I recommend you to

  int result = 0; If (! (Integer, out result)). (Baiding Contaks. Modelstet. Ademodel Arrr (binding Kantboks. Madelnam, Stringkformet ( "\" {0} \ "is invalid, please enter a valid number." Binding Kantboks. Modelnam)); return null;} return Results;
