The Html.Hidden helper renders a hidden input. For example, the following code:
@Html.Hidden("wizardStep", "1")
results in:
<input id="wizardStep" name="wizardStep" type="hidden" value="1" />
The strongly typed version of this helper is Html.HiddenFor. Assuming your model had a WizardStep property, you would use it as follows:
@Html.HiddenFor(m => m.WizardStep)
