How do I display and check a Null value in MVC?

I have an Object, say Employee with the following: 

 Employee() {
    int id;
    string name;
 }

In my view,

I currently do 

<input type="text" name="employeeName" id="employeeName" readonly="true" value="@Model.Employee.name"/>

However, in certain cases the Employee value will be null and this will give me an error, null reference error. Should I do inline checks to return an empty string if it's null or is there a better way?

would the @HTML.TextboxFor() method work better in this case?

Using Html.TextBoxFor would handle this, yes:

@Html.TextBoxFor(i => i.Employee.Name)

This will not cause a null issue. You can also use your approach with null checks, so your assumption is correct:

<input type="text" name="employeeName" id="employeeName" readonly="true" 
  value="@(Model.Employee != null ? Model.Employee.name : "")"/>

This is because you are using the objects directly, whereas TextBoxFor evaluates the expression tree and handles nulls appropriately.
