How can I check if my model is valid from inside t

问题:

I need to do a check if my model is valid from inside my Razor view. If it's valid then I want to be able to show some HTML.

How can I do this. I want something like

@if ( Model.IsValid ) {

}

but the above does not work

You can check whether or not the ModelState is valid, but keep in mind that you're only checking the validity of the ModelState at the time the web request was made:

@if (ViewData.ModelState.IsValid) {
    ...
}

Additionally, you can check validatity of a property on the model in the view:

@if (ViewData.ModelState.IsValidField("FIELD_NAME")) {
    ...
}
