MVC data annotations range validation not working properly
提问by stopher
I have a RangeValidatoron 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.
我的模型中有一个RangeValidator属性，只允许 0 到 100 之间的整数。我有一个局部视图，显示一个表单以通过 jQuery UI 对话框更新属性。我查看了源代码，可以确认数据注释属性正在正确生成。但是，验证工作不正常。它确实执行了某种验证，但它没有使用我设置的范围。值 1、10 和 100 不会产生错误。任何其他一位或两位数字值都会产生错误。但是，如果我用零填充，则所有小于 100 的值都可以。
Model:
模型：
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:
部分视图：
@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:
标记产生：
<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 TextBoxForto EditorForit chnages to numberbut I still see the same behavior.
我看到类型设置为text，如果我TextBoxFor将EditorFor它更改为 ，number但我仍然看到相同的行为。

Try [Range(0, 100)]. Remove ErrorMessagecompletely to see that you not breaking anything with wrong formatting and curly brackets.
试试[Range(0, 100)]。ErrorMessage完全删除以查看您没有用错误的格式和大括号破坏任何内容。
If pure range doesn't work properly let force (MS) be with you! :)
如果纯范围不能正常工作，让力 (MS) 与您同在！:)
