MVC5使用单选按钮与下拉框【转】

某人认为下拉列表的呈现形式不如单选按钮漂亮,我只好去测试一下单选按钮与下拉框了。测试代码如下:

1.model类Blog.cs(类型使用枚举类型,自动生成的视图会以下拉列表形式显示):

using System.ComponentModel;
using System.ComponentModel.DataAnnotations; namespace WebTest.Models
{
public enum B_Type
{

}
public class Blog
{
[Key]
public int B_Id { get; set; } [DisplayName("标题")]
public string B_Title { get; set; } [DisplayName("内容")]
public string B_Content { get; set; } [DisplayName("类型")]
public B_Type B_Type { get; set; } [DisplayName("标签")]
public string B_Tag { get; set; }
}
}

2.在web.config添加连接数据库的字符串(推荐使用sql server数据库,或者使用vs自带的localdb。这一步不会就乖乖去看入门教程,懒得写步骤),然后快捷键ctrl+shift+B 生成解决方案,然后新建带视图的控制器。

3.修改自动生成的Create.cshtml视图代码如下(仔细看一下更改部分):

<div class="form-group">
@Html.LabelFor(model => model.B_Type, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EnumDropDownListFor(model => model.B_Type, htmlAttributes: new { @class = "form-control" })</span>
@Html.ValidationMessageFor(model => model.B_Type, "", new { @class = "text-danger" })
</div>
</div> <div class="form-group">
@Html.LabelFor(model => model.B_Tag, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@*@Html.EditorFor(model => model.B_Tag, new { htmlAttributes = new { @class = "form-control" } })*@
@Html.RadioButtonFor(model=>model.B_Tag, "c#",new { htmlAttributes = new { @class = "form-control" } })C#
@Html.RadioButtonFor(model => model.B_Tag, "java", new { htmlAttributes = new { @class = "form-control" } })Java
@Html.RadioButtonFor(model => model.B_Tag, "python", new { htmlAttributes = new { @class = "form-control" } })Python</span>
@Html.ValidationMessageFor(model => model.B_Tag, "", new { @class = "text-danger" })
</div>
</div>

4.在浏览器打开Create.cshtml视图,新建一条数据,系统在自动创建数据库时会往数据库添加你新建的数据内容

5.修改Edit.cshtml视图代码如下(注意观察不同,视图呈现时会自动选中数据库存储的内容的):

<div class="form-group">
@Html.LabelFor(model => model.B_Tag, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@*@Html.EditorFor(model => model.B_Tag, new { htmlAttributes = new { @class = "form-control" } })*@
@Html.RadioButtonFor(model => model.B_Tag, "c#", new { htmlAttributes = new { @class = "form-control" } })C#
@Html.RadioButtonFor(model => model.B_Tag, "java", new { htmlAttributes = new { @class = "form-control" } })Java</span>
@Html.RadioButtonFor(model => model.B_Tag, "python", new { htmlAttributes = new { @class = "form-control" } })Python
@Html.ValidationMessageFor(model => model.B_Tag, "", new { @class = "text-danger" })
</div>
</div>

6.如果你做了一遍,就会对流程比较清楚了,对应着改自己的项目即可。现在我还是分不清哪个漂亮,不过从实现上讲,下拉列表更易实现,只需将model类中的某一字段定义为枚举类型,就不必你改代码了呀。
