I am declaring a WebGrid as follows:

@{
    WebGrid grid = null;
    if (Model.EmailAddressesOfChosenClient.Count<string>() != 0)
    {
        grid = new WebGrid(Model.EmailAddressesOfChosenClient, ajaxUpdateContainerId: "gridContent");
    }
}

Then I am trying to Render the WebGrid as follows without specifying any columns:

<div id="gridContent">
@{ if (grid != null)
   {
      @grid.GetHtml()
   }
}
</div>

My EmailAddressesOfChosenClient property of the Model is IEnumerable of strings where each string is an email address. I would like the WebGrid to contain a single column with title "Email Address" followed by rows of email address strings.

If I render it this way however, my WebGrid shows up with column heading "Length" and the rows contain the length of each email address string.

Why is that? How do I configure things so that I show the email addresses in the rows and with the right column heading? Many thanks

Why is that?

Because if you do not explicitly specify the columns, the helper uses reflection to inspect the public properties of the type and autogenerates a column for them. So the System.String has the .Length public property and thus you get a column for it.

You will need to use a custom column:

@grid.GetHtml(
    columns: grid.Columns(
        grid.Column("email", format: item => item)
    )
)

Alternatively you could define a view model and have your IEnumerable<T> use this view model instead of string.
