MVC 4 - How to conditionally disable this button?
提问by Hosea146
I would like to conditionally disable this button, or hide it, if Model.BicycleSellerListingIdis not greater than 0. Not sure how to do it.
如果该按钮Model.BicycleSellerListingId不大于 0 ，我想有条件地禁用或隐藏它。不知道该怎么做。
<div style="position:absolute; left:300px; top:633px;">
@using (Html.BeginForm("Delete", null, new { id = Model.BicycleSellerListingId }, FormMethod.Post))
{
<button type="submit">Delete Listing</button>
}
</div>
