更新來自UserControl的模型 - mvc

我有一個問題：我已經創建了一個UserControl A，A有它自己的控制器，以便在每個視圖中重新使用Usercontrol actions添加，UserControl A期望一個模型UserControlModel，我想要做的是更新包含用戶控件A的視圖的模型。更新來自UserControl的模型 - mvc

如何將UserControl的值傳遞到主視圖或包含用戶控件的任何視圖以保持該值？

一些代碼：

用戶控件控制器

public class ColorBlockUserControlController : Controller 
    { 
     /// <summary> 
     /// Callback method for ColorBlockUserControl's AJAX form. 
     /// </summary> 
     /// <param name="model">ColorModel</param> 
     /// <returns>HTML string to be dispalyed within target DIV tag.</returns> 
     [HttpPost] 
     public ActionResult DrawColor(ColorModel model) 
     { 
      if (ModelState.IsValid) 
      { 
       return Content(ColorManager.GetGradientDiv(model.RGBColor, model.Width, model.Height)); 
      } 
      else 
      { 
       return Redirect("/"); 
      } 
     } 


     [AcceptVerbs(HttpVerbs.Post)] 
     public JsonResult Sumar(int Height, int Width) 
     { 
      return Json(true); 
     } 
    }

用戶控件的HTML：

<script type="text/javascript"> 
    $(document).ready(function() { 
     var Valores = { 
      'Height': 30, 
      'Width': 30 
     }; 

     $("#btnSumar").click(function() { 
      var targetDiv = "#TargetResult"; 

      $.post(
      '/ColorBlockUserControl/Sumar', 
      Valores, 
      function (data) { 
       if (data === true) { 
        debugger; 
        $(targetDiv).html('Sumado'); 
       } 
       else { 

        alert('Failed to save the user'); 

       } 
      }, 
      'json' 
     ); 
     }); 

    }); 

</script> 

@using (Ajax.BeginForm("DrawColor", "ColorBlockUserControl", new AjaxOptions { UpdateTargetId = "color-" + Model.Id })) 
{ 
    <div>RGB (example: FFAA00)</div> 
    <div class="formLine"> 
     @Html.EditorFor(x => x.RGBColor) 
    </div> 

    @Html.ValidationMessageFor(x => x.RGBColor) 

    <div>Width</div> 
    <div class="formLine"> 
     @Html.EditorFor(x => x.Width) 
    </div> 

    <div>Height</div> 
    <div class="formLine"> 
     @Html.EditorFor(x => x.Height) 
    </div> 

    <div id="btnSumar" style="cursor:pointer;">This is a Test</div> 


    <p><input type="submit" value="Color Me!" /></p> 

    <div id="[email protected]"><!-- Will be populated by AJAX method --></div> 
}

查看與用戶控件：

@model MVCColorUserControl.Models.HomeModel 
@using MVCColorUserControl.Models 

@{ 
    ViewBag.Title = "Color Demo"; 
} 
<h2>@Model.WelcomeText</h2> 
<p> 
    A Partial Control</p> 
    @Html.Partial("UserControls/ColorBlockUserControl", new ColorModel()) 
<hr /> 
@*<p> 
    A Partial Control that is initialized on Server-Side</p> 
@{ 
    Html.RenderAction("InitializeUserControl"); 
}*@ 

@Html.ActionLink("Ir a Test View", "Test") 


@Html.ActionLink("Usando otro controller", "InNewController")

你可以使用'FormCollection'或使用強類型的意見，再加上請在這裏發表相關的代碼＃2 – Rafay

我該怎麼辦呢？ –

不能真正理解你在這裏試圖達到什麼目的，請張貼更詳細的代碼，指出你的問題（其確切地說是沒有垃圾代碼的地方）。 –

爲了回答你有關的問題的FormCollection：

在你的控制器，你可以這樣做：

[HttpPost] 
public ActionResult GetMeSomeValues(FormCollection formCollection) 
{ 
    string text = formCollection.Get("Name of the input or whatever you have in your form"); 

    //same goes for int values which you will need to convert from a string. 
    //Now if you want to pass the value to a Model simply create a new Model in here 
    //and add it. 

    var model = new Model(); 
    model.Value = text; 

    return View(model); 
}
