    <p>I have the following view which returns some text if the POnumber is null. What I think I need to have instead of the if(Model.Invoice.PONumber == null) is a check mechanism ( maybe multiple if statements ) that will check the fields LineNumber, Description, UnitOfMeasure, QtyOrdered and if any of them is null it will replace it with N/A or empty space but it will still allow the user to see the rest of information available. Do you have any sugestions? I am new to MVC and any help will be apreciated.</p> <p>Thank you in advance for your time and help,Bobby</p> <pre><code>&lt;div class="contentWrapper2"&gt; &lt;div class="content2"&gt; &lt;div class="clr lfl w100"&gt; &lt;h1&gt;Invoice Detail&lt;/h1&gt; &lt;div class="return-btn"&gt; &lt;a class="btn btnStyleC btn-back-invoice" href="@Url.Action("InvoiceHistory", "Account")"&gt; Back to Invoice List&lt;/a&gt; &lt;/div&gt; &lt;/div&gt; @if (Model.ErpError.Length &gt; 0) { &lt;div class="clr lfl w100 error"&gt; @Html.Raw(Model.ErpError) &lt;/div&gt; } else { if(Model.Invoice.PONumber == null) { &lt;div class="lfl w100 clr messaging"&gt; &lt;p&gt;No information available at the moment for current invoice.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
