ASP.NET MVC4 Validation

Question

I have a View model

public class TrainingProgramScheduledDateVM
  {

public bool IsTuesday { get; set; }

    [DataType(DataType.Time)]
    public string TueStartTime { get; set; }
    [DataType(DataType.Time)]
    public string TueEndTime { get; set; }

    public bool IsWednesday { get; set; }

    [DataType(DataType.Time)]
    public string WedStartTime { get; set; }
    [DataType(DataType.Time)]
    public string WedEndTime { get; set; }

    public bool IsThursday { get; set; }

    [DataType(DataType.Time)]
    public string ThuStartTime { get; set; }
    [DataType(DataType.Time)]
    public string ThuEndTime { get; set; }

  }

I want to put the validation i a way that. 1- If IsTuesday = true Then TueStartTime and TueEndTime should Requires. and so on for other

2- At least one boolean value should be true and relevant time should be required.

please suggest me any easy way.

Thanks

Use remote validation. For example, Here

        [Remote(
        "doesProductNameExistUnderCategory", 
        "Northwind", 
        AdditionalFields = "Category_ID",
        ErrorMessage = "Product name already exists under the chosen category. Please enter a different product name.",
        HttpMethod = "POST"
    )]
    [Required]
    public string Product_Name { get; set; }

How is that going to help with posting and validating a new model?

Can you please send the proper example.

@CodeCaster: remote validation can help you to implement very sophisticated validation: by two, three fields. It also allows to validate data by additional data from database. This is not only way, but I like this approach.

sounds good. but not suits on my case, i dont want to be post back for just validation.

I see repetition. This block:

public bool IsTuesday { get; set; }

[DataType(DataType.Time)]
public string TueStartTime { get; set; }
[DataType(DataType.Time)]
public string TueEndTime { get; set; }

Can better be abstracted into its own type, like:

public class ScheduleDate
{
    public DayOfWeek DayOfWeek { get; set; }

    public bool IsSelected { get; set; }

    [DataType(DataType.Time)]
    [RequiredIf(IsSelected)]
    public string StartTime { get; set; }

    [DataType(DataType.Time)]
    [RequiredIf(IsSelected)]
    public string EndTime { get; set; }
}

Then your TrainingProgramScheduledDateVM can contain a list of ScheduleDate objects.

I think it will not make sense. can you please send the example ?

CodeCaster Over a year ago

@SirajHussain I cannot send an example, you will have to implement this in your code.

In what assembly is defined RequiredIfAttribute? I can't find it.
