在部分視圖中過濾

我有一個PartialView，它顯示錶中的項目。我想用一些標準來過濾它們。我的觀點：在部分視圖中過濾

@model Bike_Store.Models.PartsViewModel 

<form method="get"> 
    <div> 
     <label>Category: </label> 
     @Html.DropDownList("categorie", Model.Categories as SelectList, 
     htmlAttributes: new { @class="form-control"}) 

     <label>Brand: </label> 
     @Html.DropDownList("brand", Model.Brands as SelectList, 
     htmlAttributes: new { @class="form-control" }) 
     <input type="submit" value="Filter" />   
    </div> 
</form> 

<table>...</table>

我的控制器：

[HttpGet] 
    public ActionResult PartsPartial(int? categorie, int? brand) 
    { 
     IQueryable<bs_parts> parts = _db.bs_parts.Include(p => p.bs_categories); 
     if (categorie != null && categorie != 0) 
     { 
      parts = parts.Where(p => p.parts_category_id == categorie); 
     } 
     if (brand != null && brand != 0) 
     { 
      parts = parts.Where(p => p.parts_brand_id == brand); 
     } 

     List<bs_categories> categoriesList = _db.bs_categories.ToList(); 
     List<bs_brands> brandsList = _db.bs_brands.ToList(); 

     PartsViewModel pvm = new PartsViewModel 
     { 
      Parts = parts.ToList(), 
      Categories = new SelectList(categoriesList, "categories_id", "categories_name"), 
      Brands = new SelectList(brandsList, "brands_id", "brands_name") 
     }; 
     return PartialView(pvm); 
    }

過濾這種方式正常工作與正常View。但是，當我嘗試與Partial View一樣做時，它不起作用，頁面只是重新加載。我把break point檢查，如果我的Get方法工作，當我按Filter按鈕，我注意到它不。問題是什麼？

我打電話Partial View從菜單中有：

@Ajax.ActionLink(
"Parts", 
"PartsPartial", 
new 
{ 
    value1 = 1 
}, 
new AjaxOptions 
{ 
    HttpMethod = "GET", 
    InsertionMode = InsertionMode.Replace, 
    UpdateTargetId = "content" 
}, new { @class = "button" } 
) 
<div class="content" id="content"> 

</div>

@ Html.Partial（）或@ Html.RenderPartial不做任何con troller調用，並且幾乎不能用你的模型呈現html視圖。考慮使用Html.RenderAction代替 – Igor
