     <input type="submit" value="delete" /> 

    } 
</body> 
</html> 
<h2>displayingrid</h2>

我得到低於錯誤必須綁定數據源才能對mv執行此操作C5。在同一頁上，我想顯示一個表單和一個webgrid。所以我創建了一個局部視圖，並在一個視圖內渲染，但是當我運行受到錯誤的時候就到了。請建議我解決這個錯誤。

您沒有將模型發送到視圖和局部視圖。

編輯：

首先，你不能有兩款車型在同一視圖像你這樣用：

@model C3CardKYC.Models.intermediate @Model C3CardKYC.Models.detailslistmodel

您可以創建一個包含這兩個容器的容器，然後在視圖中放置該容器。

其次，您需要在控制器操作中獲取/生成模型，然後傳遞該模型以查看。

我想在主要的Crate視圖中，您想使用C3CardKYC.Models.intermediate，然後將C3CardKYC.Models.detailslistmodel傳遞給局部視圖。

如果是這樣的話，你可以通過定義一個類來完成：

public class ContainerClass { 

    public C3CardKYC.Models.detailslistmodel model1 { get; set; } 
    public C3CardKYC.Models.detailslistmodel model2 { get; set; } 
}

將在您的視圖中使用的模型：

@model namespace.ContainerClass

然後在你的控制器動作，您需要生成此類的一個對象（ContainerClass），設置model1和model2屬性並將生成的對象傳遞給視圖：

return View(modelObject);

完成所有工作後，在您的視圖中，您可以使用Model.model1訪問intermediate和Model.model2以訪問detailslistmodel。

最後，你必須通過模型的局部視圖太：

@Html.Partial("path", Model.model2)

請建議我如何回報模型。 –
