Asp.net MVC3验证 [英] Asp.net MVC3 validation

问题描述

我有asp.net MVC3应用验证的地方通过在模型添加验证属性来完成。
例如。

[必需（的ErrorMessage =必填字段）
        [显示（NAME =SurveyName）]
        [数据类型（DataType.Text）
        公共字符串SurveyName {获取;设置;}

然后，我创建鉴于文本框

@ Html.TextBoxFor（型号=＆GT; model.SurveyQuestions [I] .SurveyName）

和添加验证信息

  @ Html.ValidationMessageFor（型号=＆GT; model.SurveyQuestions [I] .SurveyName）
 

下面是场景创建文本框5与同样具有模型属性Surveyname循环，我想验证只有第一个文本框和文本框的其余部分没有验证。

这可能吗？

编辑：

我用低于code为文本框的其余部分，但它发生在这些领域也验证。

  @ Html.TextBox（SurveyQuestions [+ I +]。提问，@ Model.SurveyQuestions [I]。提问）
 

解决方案

所以最后我得到了解决，但我认为这是不正确的方法。但它解决了我的问题。
我的步骤做，以解决这个问题 -

1. 我观察到的HTML对此有一个验证错误输入字段。输入字段将有额外的属性，例如数据-VAL-要求和数据val的


2. 然后我说这些领域的文本框，需要进行验证。


3. 然后我说Html.Validation（）为文本框与验证消息。

我的最后code看起来像

  @if（我== 0）
                {
                    @ Html.TextBoxFor（型号=＆GT; model.SurveyQuestions [I]。提问，新的字典＆LT;字符串对象＆gt; {{数据-VAL-要求的，需要}，{数据-VAL，真 }，{称号，问题+（I + 1）}，{类，QuestionTextBox}}）
                    ＆LT; BR /＆GT;
                    @ Html.ValidationMessage（SurveyQuestions [0]。提问，至少需要一个问题。）
                }
                其他
                {
                    @ Html.TextBoxFor（型号=＆GT; model.SurveyQuestions [I]。提问，新{@class =QuestionTextBox@title =问题+（I + 1）}）
                }
 

I have asp.net MVC3 app where validations are done by adding validation attribute in model. e.g.

[Required(ErrorMessage = "Required field")] [Display(Name = "SurveyName")] [DataType(DataType.Text)] public string SurveyName {get;set;}

Then I create text box in view

@Html.TextBoxFor(model => model.SurveyQuestions[i].SurveyName)

and add validation message

@Html.ValidationMessageFor(model => model.SurveyQuestions[i].SurveyName)

Scenario here is I create 5 textbox with for loop with same model property Surveyname and I want to validate only first textbox and no validations for rest of the textbox.

Is this possible?

Edit:

I used below code for rest of the textboxes but it validation occurs on these fields also.

@Html.TextBox("SurveyQuestions[" + i + "].Question", @Model.SurveyQuestions[i].Question)

解决方案

So finally I got the solutions, though I think it's not the correct way. But it solved my issue. Steps I did to fix the issue -

1. I observed Html for input fields for which there is an validation error. The input field will have additional attributes such as "data-val-required" and "data-val"
2. Then I added these fields to textbox which needs to be validated.
3. Then I added Html.Validation() for textbox with validation message.

My final code looks like

             @if (i == 0)
                {
                    @Html.TextBoxFor(model => model.SurveyQuestions[i].Question, new Dictionary<string, object> { { "data-val-required", "required" }, { "data-val", "true" },  { "title", "Question " + (i + 1) }, {"class","QuestionTextBox"} })           
                    <br />
                    @Html.ValidationMessage("SurveyQuestions[0].Question", "At least one question is required.")
                }
                else
                { 
                    @Html.TextBoxFor(model => model.SurveyQuestions[i].Question, new { @class = "QuestionTextBox", @title = "Question " + (i + 1) })    
                }
