MVC 4 - このボタンを条件付きで無効にするにはどうすればいいですか？

Question

Model.BicycleSellerListingIdが0より大きくない場合、条件付きでこのボタンを無効にするか、非表示にしたいと思います。

<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> 

Answer 1

<div style="position:absolute; left:300px; top:633px;"> 
@using (Html.BeginForm("Delete", null, new { id = Model.BicycleSellerListingId }, FormMethod.Post)) 
{ 
    if(Model.BicycleSellerListingId < 0){ 
     <button type="submit">Delete Listing</button> 
    } 
} 
</div> 

OR

@if(Model.BicycleSellerListingId < 0){ 
    <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> 
} 

OR

<div style="position:absolute; left:300px; top:633px;"> 
@using (Html.BeginForm("Delete", null, new { id = Model.BicycleSellerListingId }, FormMethod.Post)) 
{ 
    <button type="submit" @((Model.BicycleSellerListingId < 0) ? "disabled" : "")>Delete Listing</button> 
} 
</div>
