有人可以帮助我如何将我的参数从组合框绑定到我的控制器中我的一个动作的参数。我正在使用 DevExpress 控制套件，这是我的代码：

 [HttpPost]
 public ActionResult Filter(string filterCriteria)
 {
     ViewData.Model = Repository.GetReports(filterCriteria);
     return RedirectToAction("Index");
 }

这是我的观点：

<div style="float:right;padding-bottom:20px;" >
@using (Html.BeginForm())
{
<table><tr><td>
Filter by Keyword:</td>
<td>
@Html.DevExpress().DropDownEdit(
    settings =>
    {
        settings.Name = "checkComboBox";
        settings.Width = 210;
        settings.Theme = Utils.CurrentTheme;
        settings.Properties.DropDownWindowStyle.BackColor = System.Drawing.Color.FromArgb(0xEDEDED);
        settings.Properties.ClientSideEvents.ValueChanged = "function(s, e) {e.customArgs[\"filterCriteria\"] = checkComboBox.Name.toString();}";

        settings.SetDropDownWindowTemplateContent(c =>
        {
            @Html.DevExpress().ListBox(
                listBoxSettings =>
                {
                    listBoxSettings.Name = "checkListBox";
                    listBoxSettings.SkinID = "CheckComboBoxListBox";
                    listBoxSettings.CallbackRouteValues = new { Controller = "Report", Action = "Filter" };
                    listBoxSettings.Theme = Utils.CurrentTheme;
                    listBoxSettings.ControlStyle.Border.BorderWidth = 2;
                    listBoxSettings.ControlStyle.BorderBottom.BorderWidth = 1;
                    listBoxSettings.ControlStyle.BorderBottom.BorderColor = System.Drawing.Color.FromArgb(0xDCDCDC);
                    listBoxSettings.Width = System.Web.UI.WebControls.Unit.Percentage(100);
                    listBoxSettings.Height = 100;

                    listBoxSettings.Properties.SelectionMode = ListEditSelectionMode.CheckColumn;

                    listBoxSettings.Properties.ClientSideEvents.SelectedIndexChanged = "OnListBoxSelectionChanged";
                }
            ).BindList(Repository.GetKeywords())
            .Render();
            ViewContext.Writer.Write("<table style=\"width:100%\"><tr><td align=\"right\">");
            @Html.DevExpress().Button(
                buttonSettings =>
                {
                    buttonSettings.Name = "buttonClose";
                    buttonSettings.Text = "Close";
                    buttonSettings.Style.Add("float", "right");
                    buttonSettings.Theme = Utils.CurrentTheme;
                    buttonSettings.ClientSideEvents.Click = "function(s, e){ checkComboBox.HideDropDown(); }";
                }
            )
            .Render();
            ViewContext.Writer.Write("</td></tr></table>");
        });
        settings.Properties.EnableAnimation = true;
        settings.Properties.ClientSideEvents.TextChanged = "SynchronizeListBoxValues";
        settings.Properties.ClientSideEvents.DropDown = "SynchronizeListBoxValues";
    }
).GetHtml()
</td><td>
@Html.DevExpress().Button(
    settings =>
    {
        settings.Name = "btnApply";
        settings.ControlStyle.CssClass = "button";
        settings.Text = "Apply";
        settings.UseSubmitBehavior = true;
        settings.Theme = Utils.CurrentTheme;
        settings.Width = 80;
        settings.RouteValues = new { Controller = "Report", Action = "Filter" };
    }
).GetHtml()
</td><td>
@Html.DevExpress().Button(
    settings =>
    {
        settings.Name = "btnClear";
        settings.ControlStyle.CssClass = "button";
        settings.Text = "Clear";
        settings.ClientSideEvents.Click = "function(s, e){ ASPxClientEdit.ClearEditorsInContainer(); }";
        settings.Theme = Utils.CurrentTheme;
        settings.Width = 80;
    }
).GetHtml()
</td></tr></table>
}
</div>

我基本上在底部有一个网格视图，我想用它上面的下拉列表进行过滤。我通过使用一个按钮来调用该操作来过滤我的收藏。在这个例子中，我只是试图传回控件的名称，即

settings.Properties.ClientSideEvents.ValueChanged = "function(s, e) {e.customArgs[\"filterCriteria\"] = checkComboBox.Name.toString();}";

只是想看看我是否能够传回任何值，但这失败了。有人可以详细说明一下这样做的方法吗？谢谢，

根据我收集的信息，您想要检索在控制器端的“checkListBox”列表框中选择的多个项目。如果是这样，请按以下方式使用ListBoxExtension.GetSelectedValues方法：

[HttpPost]
public ActionResult Filter(string filterCriteria)
{
    //listBoxSettings.Name = "checkListBox";

    string[] values = ListBoxExtension.GetSelectedValues<string>("checkListBox");
    filterCriteria = values...

    ViewData.Model = Repository.GetReports(filterCriteria);
    return RedirectToAction("Index");
}

我知道这是一个较老的问题，但我想我可能只是添加使用viewbagwhich 允许您将数据从控制器发送到视图，反之亦然。这是mdsn的一个示例。

控制器

public ActionResult Index()
{
    ViewBag.MyMessageToUsers = "Hello from me.";
    ViewBag.AnswerText = "Your answer goes here.";

    return View();
}

看法

@ViewBag.MyMessageToUsers
@Html.TextBox("AnswerText")
