Devexpress 在asp.net mvc中选择的DevXPress组合框已更改索引

控制器：

public ActionResult ComboBox()
{

List<ComboBoxClass> Products = new List<ComboBoxClass>();
Products.Add(new ComboBoxClass { ProductName = "Masa" });
Products.Add(new ComboBoxClass { ProductName = "Sandalye" });
Products.Add(new ComboBoxClass { ProductName = "Bilgisayar" });
Products.Add(new ComboBoxClass { ProductName = "Laptop" });
Products.Add(new ComboBoxClass { ProductName = "Kulaklık" });
Products.Add(new ComboBoxClass { ProductName = "Bardak" });
Products.Add(new ComboBoxClass { ProductName = "Kalem" });
Products.Add(new ComboBoxClass { ProductName = "Seramik" });
Products.Add(new ComboBoxClass { ProductName = "Telefon" });

ViewData["Products"] = Products;

return View(Products);
}

public ActionResult SelectedItemHere(string SelectedItem)
{
// Processes..
return View();
}

我有产品。我在ComboBox上列出了所有产品。如何将我的SelectedIndexChanged值传递给ActionResult

我想在“string SelectedItem”下面看到所选值

您需要在组合框中添加以下代码

settings.Properties.ClientSideEvents.SelectedIndexChanged = "SelectedId";

之后

布局中的Javascript代码

function SelectedId() {
var data= {
SelectedItem: BenimComboBox.GetValue(),
};

$.ajax({
url: "/YOUR CONTROLLER/YOUR ACTİONRESULT",
type: "POST",
dataType: "json",
contentType: 'application/json',
data: JSON.stringify(data),

最后,

控制器：

public ActionResult ComboBox()
{

List<ComboBoxClass> Products = new List<ComboBoxClass>();
Products.Add(new ComboBoxClass { ProductName = "Masa" });
Products.Add(new ComboBoxClass { ProductName = "Sandalye" });
Products.Add(new ComboBoxClass { ProductName = "Bilgisayar" });
Products.Add(new ComboBoxClass { ProductName = "Laptop" });
Products.Add(new ComboBoxClass { ProductName = "Kulaklık" });
Products.Add(new ComboBoxClass { ProductName = "Bardak" });
Products.Add(new ComboBoxClass { ProductName = "Kalem" });
Products.Add(new ComboBoxClass { ProductName = "Seramik" });
Products.Add(new ComboBoxClass { ProductName = "Telefon" });

ViewData["Products"] = Products;

return View(Products);
}

public ActionResult SelectedItemHere(string SelectedItem)
{
// Processes..
return View();
}

按客户端访问DevExpress组合框所选索引

ComboxSelectedIndexChanged（e，s）上的函数{ //检查所选索引 var selected_index=e.lastSuccessValue； 警报（选定的索引）； }

工作非常完美，只是我需要做一点小改动。发布它只是为了防止其他用户无法运行该函数。settings.Properties.ClientSideEvents.SelectedIndexChanged=“函数（s，e）{getData（）}”；工作做得很好，只是我得做点小改动。发布它只是为了防止其他用户无法运行该函数。settings.Properties.ClientSideEvents.SelectedIndexChanged=“函数（s，e）{getData（）}”；
