How can I check ModelState.IsValid from inside my Razor view
提问by Samantha J T Star
I have the following in my action method:
我的操作方法中有以下内容：
if (!ModelState.IsValid)
return View(vm);
In the view I want to not present a submit key to allow deletion if the model state is not valid. Is there a way that I can do this? Is model state available in the view?
在视图中，如果模型状态无效，我不想提供提交键以允许删除。有没有办法做到这一点？模型状态在视图中可用吗？
Update: I have implemented this based on the answers I was given:
更新：我已经根据我给出的答案实现了这一点：
<div class="adm_td0" style=" padding: 0;">
@if (ViewData.ModelState.IsValid) {
<input type='submit' value='Delete' name='SubmitAction' />
}
<input type='submit' value='Cancel' name='SubmitAction' />
</div>

模型状态在视图中可用吗？
Of course:
当然：
@if (!ViewData.ModelState.IsValid)
{
<div>There are some errors</div>
}

It's not common to need this in the view itself, but you can access it like so:
在视图本身中需要它并不常见，但您可以像这样访问它：
@ViewData.ModelState.IsValid
