    <p>I think you have <strike>three</strike> four options. First when you are building your SelectList or enumerable of SelectItemList, prepend the selection with your option label and default value. Putting it at the top will make it the default if some other value isn't already chosen in the model. Second, you could build the select (and options) "by hand" in the view using a loop to create the options. Again, prepending your default selection if one isn't supplied in the model. Third, use the DropDownList extension, but modify the value of the first option using javascript after the page is loaded.</p> <p>It doesn't seem to be possible to use the DropDownList extension to assign a value to an optionLabel as it is hard-coded to use <code>string.Empty</code>. Below is the relevant code snippet from <a href="http://www.codeplex.com/aspnet" rel="nofollow noreferrer">http://www.codeplex.com/aspnet</a>.</p> <pre><code> // Make optionLabel the first item that gets rendered. if (optionLabel != null) { listItemBuilder.AppendLine(ListItemToOption(new SelectListItem() { Text = optionLabel, Value = String.Empty, Selected = false })); } </code></pre> <p><strong>EDIT</strong>: Finally, the best way is to have your model take a Nullable value and mark it as required using the RequiredAttribute. I would recommend using a view-specific model rather than an entity model for the view. Since the value is Nullable, the empty string will work fine if posted back without choosing a value. Setting it as a required value will cause the model validation to fail with an appropriate message that the value is required. This will allow you to use the DropdownList helper as is.</p> <pre><code>public AreaViewModel { [Required] public int? AreaId { get; set; } public IEnumerable&lt;SelectListItem&gt; Areas { get; set; } ... } @Html.DropDownListFor( model =&gt; model.AreaId, Model.Areas, "Select Area Id" ) </code></pre>

    1. COThank you. I now create a List<SelectListItem> object, insert a default option with value 0 at index 0 and pass that to Html.DropDownList. It works a treat.

    2. COThanks that helped me as well! It's sad that even with MVC 3 it isn't possible to add the default value :/

    3. CO@LanFeusT - this was answered long before MVC3. I've updated it for a better method of dealing with it from a model perspective, esp. with MVC3.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
