用于基本类型的 ASP.NET MVC 4 编辑器模板 [英] ASP.NET MVC 4 Editor Template for basic types
问题描述
我已经为数字输入创建了一个模板，如果我这样做了
I've created a template for Number input and if I do
@Html.EditorFor(model => model.SomeValue, "Number")
它工作正常并且使用了模板.
it works fine and the template is used.
但是这不起作用:
@Html.EditorFor(model => model.SomeValue)
为什么我需要为基本类型指定编辑器模板的名称?
Why do I need to specify the name of the Editor Template for basic types ?
推荐答案
编辑器模板按惯例工作.模板名称必须与类型名称匹配.例如，如果 SomeValue 是 int 类型，您可以在 ~/Views/Shared/EditorTemplates/Int32.cshtml 编写自定义编辑器模板，其中将会被使用.在这种情况下，当您编写 @Html.EditorFor(model => model.SomeValue) 时，所有整数类型都将使用此自定义模板.
Editor templates work by convention. The name of the template must match the name of the type. So for example if SomeValue is an int type you could write a custom editor template at ~/Views/Shared/EditorTemplates/Int32.cshtml which will be used. In this case all integer types will use this custom template when you write @Html.EditorFor(model => model.SomeValue).
如果您不想覆盖整数类型的所有模板，您可以编写一个特定的命名模板 ~/Views/Shared/EditorTemplates/Number.cshtml，您只能将其用于某些属性将此模板名称指定为 EditorFor 助手的第二个参数:@Html.EditorFor(model => model.SomeValue, "Number") 或通过装饰您的视图模型属性使用 [UIHint] 属性:
If you don't want to override all templates for integer types you could write a specific named template ~/Views/Shared/EditorTemplates/Number.cshtml that you could use only for some properties by specifying this template name as second argument to the EditorFor helper: @Html.EditorFor(model => model.SomeValue, "Number") or by decorating your view model property with the [UIHint] attribute:
[UIHint("Number")]
public int SomeValue { get; set; }
然后简单地使用 @Html.EditorFor(model => model.SomeValue) 将呈现 Number.cshtml 自定义模板.
and then simply using @Html.EditorFor(model => model.SomeValue) will render the Number.cshtml custom template.
我还建议您阅读 Brad Wilson 的 blog post 关于 ASP.NET MVC 中的默认模板.
