Textboxfor不显示字符串格式 [英] Textboxfor not showing the string format

问题描述

嗨朋友们，



我已经为它进行了以下初始投资代码

型号代码

 [DataType（DataType.Currency）] 
 [必需（ErrorMessage =  < span class =code-string>需要初始投资）] 
 [DisplayFormat（ApplyFormatInEditMode =  true ，DataFormatString =   {0：C}）] 
 [显示（名称=  初始投资）] 
 [RegularExpression（ < span class =code-string> ^ [1-9] + [0-9] * $，ErrorMessage =  初始投资是数字）] 
  public   string  InitialInvestment { get ;  set ; } 
 

Aspx代码

<％：Html.TextBoxFor（InitialInvestment => Model.InitialInvestment。，new {@class =textbox，style =width：105px，maxlength =15}）％> 
 

但这不是以货币格式显示



请帮我解决问题



谢谢

解决方案

，ErrorMessage = 初始投资为数字）]
public string InitialInvestment { get ; set ;}

Aspx代码

<％：Html.TextBoxFor（InitialInvestment => Model.InitialInvestment。，new {@class =textbox，style =width：105px，maxlength =15}）％> 
 

但这不是以货币格式显示



请帮我解决问题



谢谢

你错误地使用了Lambda表达式在文本框中



替换

<％：Html.TextBoxFor（InitialInvestment => Model.InitialInvestment。，new {@class =textbox，style =width：105px，maxlength =15}）％> 

with

<％：Html.TextBoxFor（m => m.InitialInvestment，new {@class = textbox，style =width：105px，maxlength =15}）％> 

现在尝试以上格式，你应该让它运行。



或



你甚至不需要使用注释。删除

 DisplayFormat（ApplyFormatInEditMode =  true ，DataFormatString =   {0：C}）] 

并写下以下内容

 @ Html.TextBoxFor（model => model.InitialInvestment，new {@class =textbox，id =InitialInvestment，Value = String.Format（{0：C}，Model.InitialInvestment）}）

Hi Friends,

I have put it the following code for the initial investment
Model code

[DataType(DataType.Currency)]
[Required(ErrorMessage = "Initial investment is required")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:C}")]
[Display(Name = "Initial Investment")]
[RegularExpression("^[1-9]+[0-9]*$", ErrorMessage = "Initial investment is numeric")]
public string InitialInvestment { get; set; }

Aspx code

<%: Html.TextBoxFor(InitialInvestment => Model.InitialInvestment., new { @class = "textbox", style = "width:105px", maxlength = "15"})%>

but this is not displaying in currency format

Please help me to solve the issue

Thanks

解决方案

", ErrorMessage = "Initial investment is numeric")] public string InitialInvestment { get; set; }

Aspx code

<%: Html.TextBoxFor(InitialInvestment => Model.InitialInvestment., new { @class = "textbox", style = "width:105px", maxlength = "15"})%>

but this is not displaying in currency format

Please help me to solve the issue

Thanks

You have the wrong usage of Lambda Expressions in Textbox

Replace

<%: Html.TextBoxFor(InitialInvestment => Model.InitialInvestment., new { @class = "textbox", style = "width:105px", maxlength = "15"})%>

with

<%: Html.TextBoxFor(m=>m.InitialInvestment , new { @class = "textbox", style = "width:105px", maxlength = "15"})%>

Now try the above format, you should get it running.

OR

You even dont need to use annotations for that. Remove

DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:C}")]

and write the following

@Html.TextBoxFor(model => model.InitialInvestment, new { @class = "textbox", id = "InitialInvestment", Value=String.Format("{0:C}",Model.InitialInvestment) })
