Sure, here are a few ways to check if a model property is null in a Razor view:

Using the if statement:

Razor CSHTML

if (Model.Property != null)
{
    // Do something with the property
}
else
{
    // The property is null
}

Using the is operator:

Razor CSHTML

if (Model.Property is string)
{
    // The property is a string
}
else
{
    // The property is null or not a string
}

Using the IsNullOrEmpty method:

Razor CSHTML

if (string.IsNullOrEmpty(Model.Property))
{
    // The property is null or empty
}
else
{
    // The property is not null or empty
}

Which method you use will depend on your specific needs. For example, if you only need to check if the property is null, then the if statement or the is operator will suffice. However, if you also need to check if the property is empty, then you should use the IsNullOrEmpty method.

Here is an example of how to use the IsNullOrEmpty method to check if a model property is null or empty:

Razor CSHTML

@if (string.IsNullOrEmpty(Model.Name))
{
    // The name property is null or empty
}
else
{
    // The name property is not null or empty
}

Try this 


<div id="divLoading">
       @if (Model != null && !String.IsNullOrEmpty(Model.Record))
{
    <label for="record">add record</label>
}
else
{ 
    <label for="remove">remove</label>
}
 
    </div>

 hope it helps you
