Question: how can i disable the list box 

```
Html.ListBox("Organization", Model.OrgListbox as MultiSelectList)

```

Answer: 
You use the htmlAttributes parameter:

```
Html.ListBox("Organization", Model.OrgListbox as MultiSelectList, new { disabled = "disabled" })

```
If you want to add the disabled attribute to the HTML then you would do this:

```
Html.ListBox("Organization", Model.OrgListbox as MultiSelectList, new { disabled = "disabled" })

```

This calls the overload of Html.ListBox where you can specify htmlAttributes that are added to the rendered HTML.

Alternatively you could use jQuery, doing something like this:

```
$("#controlId).attr("disabled","disabled");

```
