In a model of my ASP.NET MVC application I would like validate a textbox as required only if a specific checkbox is checked.
Something like
public bool retired {get, set};
[RequiredIf("retired",true)]
public string retirementAge {get, set};
How can I do that?
Thank you.
Using NuGet Package Manager I intstalled this: https://github.com/jwaliszko/ExpressiveAnnotations
And this is my Model:
using ExpressiveAnnotations.Attributes;
public bool HasReferenceToNotIncludedFile { get; set; }
[RequiredIf("HasReferenceToNotIncludedFile == true", ErrorMessage = "RelevantAuditOpinionNumbers are required.")]
public string RelevantAuditOpinionNumbers { get; set; }
I guarantee you this will work!
Try my custom validation attribute:
[ConditionalRequired("retired==true")]
public string retirementAge {get, set};
It supports multiple conditions.
