查詢字符串我通過我的查詢字符串中_Layout.cshtml頁FormMethod.Post返回在MVC4
<li>@Html.ActionLink("Shopping", "Index1", new { controller = "Shopping", UserID = "Admin1" })</li>
我有一個更新視圖更新從文本框
@using (Html.BeginForm("Update", "Shopping", new { id = Request.QueryString["UserID"] }, FormMethod.Post, new { id = "myForm" }))
{
@Html.Hidden("id", @Request.QueryString["UserID"] as string)
@Html.Hidden("productid", item.ProductID as string)
@Html.TextBox("qty", item.Quantity)
@Html.Hidden("unitrate", item.Rate)
<input type="submit" value="Update" />
}
值在第一次發佈,我得到這樣的網址
http://localhost:61110/Shopping/Index1?UserID=Admin1
但第二次,後後,我拿到它時的形式張貼這樣
http://localhost:61110/Shopping/Index1
的URL如何在任何時候都得到查詢字符串值。
我也試過這個mvc3: html.beginform search returning empty querystring
但不可能得到第二次交
任何建議的查詢字符串。
編輯:更新操作代碼
[HttpPost]
public ActionResult Update(string id, string productid, int qty, decimal unitrate)
{
if (ModelState.IsValid)
{
int _records = UpdatePrice(id,productid,qty,unitrate);
if (_records > 0)
{
return RedirectToAction("Index1", "Shopping",new { id = Request.QueryString["UserID"] });
}
else
{
ModelState.AddModelError("","Can Not Update");
}
}
return View("Index1");
}
public int UpdatePrice(string id,string productid,int qty,decimal unitrate)
{
con.Open();
var total = qty * unitrate;
SqlCommand cmd = new SqlCommand("Update [Table_name] Set Quantity='" + qty + "',Price='" + total + "' where [User ID]='" + id + "' and [Product ID]='" + productid + "'", con);
cmd.Parameters.AddWithValue("@total", total);
return cmd.ExecuteNonQuery();
}
你可以發佈你的'更新'行動代碼?該帖子後的網址應該如何?像'http:// localhost:61110/Shopping/Index1?UserID = Admin1'?那麼你想保留'UserID = Admin1'部分嗎? – nemesv
我需要的網址發佈querystring http:// localhost:61110/Shopping/Index1?UserID = Admin1 – kk1076
