If value is null put an empty string on razor template?

I have a razor template like below. I want to check if the value in the input field is null, put a empty string, if the @UIManager.Member.EMail has a value, put its value. How can I do that?

Normal Input:

<!-- language: lang-html -->

<input name="EMail" id="SignUpEMail" type="text" class="Input" 
       value="@UIManager.Member.EMail" validate="RequiredField" />

Razor Syntax Attempt:

<!-- language: lang-html -->

<input name="EMail" id="SignUpEMail" type="text" class="Input" validate="RequiredField"
       value="@(UIManager.Member == null) ? string.Empty : UIManager.Member.EMail" />

The value is shown in the input field is:

True ? string.Empty : UIBusinessManager.MemberCandidate.EMail

This is exactly what the NullDisplayText property on [DisplayFormat] attribute is for.

Add this directly on your model:

<!-- language: lang-cs -->

[DisplayFormat(NullDisplayText="", ApplyFormatInEditMode=true)]
public string EMail { get; set; }
