Getting Error in using user control(.ascx) on asp.net mvc layout page

Question

I am integrating Asp.net User control(.ascx) in my Mvc Layout page i.e is master page and i am using razor engine.

Error:Error executing child request for handler

'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerWrapper ascx.
                  Control '1_hdfData' of type 'HiddenField' must be placed inside a form tag with runat=server.

This is my code:

_Layout.cshtml:

@Html.Partial("~/UserControls/Data.ascx")

Data.ascx:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Data.ascx.cs" Inherits="MyNameSpace.Data" %>
                 <asp:HiddenField ID="hdfData" runat="server" />
                --Rest all other asp.net server side controls---.

Data.ascx.cs:

namespace MyNameSpace.Data
                {
                     public partial class Data : ViewUserControl
                     {
                         //Page_Load events and other code
                     }
                }

Is it like if i am inheriting User Control(.ascx) from ViewUserControl so i cant use asp.net control?

Can anybody help me with this?

just need to add form tag in usercontrol

Give different id to all form tag and use it.

I am sharing one idea, but it's not good practice.

@Html.Partial("_ASCX_FILE")

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<dynamic>" %>
<%@ Register Assembly="SomeAssembly" Namespace="SomeNs" TagName="ASCX_FILE" %>

<ASCX_FILE:SomeControl runat="server" ID="fooControl" />

Possibly above solution can sort out your issue.

Suggesting again, try using pure MVC flavor. :)
