MVC data annotations range validation not working

I have a RangeValidator on a property in my model to only allow Integers that are between 0 and 100. I have a partial view that displays a form to update the property via a jQuery UI dialog. I have looked at the source and can confirm that the data annotation attributes are being generated properly. However, the validatation isn't working properly. It does perform some kind of validation, but it isn't using the range I'm setting. The values 1, 10, and 100 do not produce the error. Any other single or two digit value produces the error. However, if I pad with zeros, all values less than one hundred are fine.

Model:

public class MyModel
{
  ...
  [Required(ErrorMessage = "{0} is required")]
  [Range(typeof(int), "0", "100", 
         ErrorMessage = "{0} can only be between {1} and {2}")]
  public int Percentage { get; set; }
  ...
}

Partial View:

@model MyApp.Models.Partials.MyModel

<div id="myDialog" class="editModal" title="Update Percentage">
  @using (Ajax.BeginForm("UpdatePercentage", "MyController", 
                         new AjaxOptions() { HttpMethod = "Post", 
                                             OnSuccess = "onUpdateSuccess" }, 
                         new { name = "myForm" }))
  {
    @Html.ValidationSummary(null, new { style = "width:auto;max-width:22em;               
                                                 float:left;clear:both;" })    
    <div style="width:auto;float:left;clear:both;">
      <div style="width:10em;float: left;text-align:right;clear:left;">
        @Html.Label("Percentage:")
      </div>
      <div style="width:12em;margin-left:1em;float:left;clear:right;">
        @Html.TextBoxFor(m => m.Percentage)
      </div>
    </div>
    <div style="width:23em;clear:both;text-align:center;">
      <hr />
      <input type="button" value="Cancel" class="cancelModalButton" 
             data-modal="myDialog" />
      <input type="submit" value="Submit" class="submitModalButton" 
             data-modal="myDialog" data-form="myForm" />
    </div>
  }
</div>

Markup produced:

<div id="myDialog" class="editModal" title="Update Percentage">
  <form action="/Web/MyController/UpdatePercentage?Length=3" 
        data-ajax="true" data-ajax-method="Post" data-ajax-success="onUpdateSuccess" 
        id="form2" method="post" name="myForm">
    <div class="validation-summary-valid" data-valmsg-summary="true" 
         style="width:auto;max-width:22em;float:left;clear:both;">
      <ul>
        <li style="display:none"></li>
     </ul>
    </div>
    <div style="width:auto;float:left;clear:both;margin-bottom:.75em;">
      <div style="width:10em;float: left;text-align:right;clear:left;">
        <label for="Percentage:">Percentage:</label>
      </div>
      <div style="width:12em;margin-left:1em;float:left;clear:right;">
        <input data-val="true" data-val-number="The field Percentage must be a number." 
               data-val-range="Percentage can only be between 0 and 100" 
               data-val-range-max="100" data-val-range-min="0" 
               data-val-required="Percentage is required" id="Percentage" 
               name="Percentage" type="text" value="10" />
      </div>
    </div>
    <div style="width:23em;clear:both;text-align:center;">
      <hr />
      <input type="button" value="Cancel" class="cancelModalButton" data-modal="myDialog" />
      <input type="submit" value="Submit" class="submitModalButton" data-modal="myDialog" data-form="myForm" />
    </div>
  </form>
</div>

I see that the type is set to text, and if I change my TextBoxFor to EditorFor it chnages to number but I still see the same behavior.

回答1:

I had this exact problem and found the solution here. You need to upgrade the following:

jQuery Validation (at least 1.11.1)
Microsoft jQuery Unobtrusive Validation (at least 2.0.30116.0)
Microsoft jQuery Unobtrusive Ajax (at least 2.0.30116.0)

The problem was introduced by breaking changes in jQuery 1.9.1

回答2:

Try [Range(0, 100)]. Remove ErrorMessage completely to see that you not breaking anything with wrong formatting and curly brackets.

If pure range doesn't work properly let force (MS) be with you! :)
