ASPxGridView not works in my ASP.NET MVC solution - asp.net-mvc

Question

I'm using ASPxGridView and updating with data from DataTable which, works fine.
But when I'm trying to use edit, update, delete, paging, sorting functions I get in trouble.
The buttons are displayed but the function doesn't work when I click them.
Here is my Sample.aspx file:
[ASPx]
<dx:aspxgridview ID="grid" ClientInstanceName="grid" runat="server"
OnDataBinding="grid_DataBinding" Width="100%" EnableCallBacks="false">
<Settings ShowTitlePanel="True" />
<SettingsText Title="Tabla" />
<SettingsPager PageSize ="10" ShowSeparators="true" PageSizeItemSettings-Items="20" >
<PageSizeItemSettings Visible="true" />
</SettingsPager>
</dx:aspxgridview>
The code behind Sample.aspx.cs :
[C#]
using System;
using System.Data;
using System.Web.Mvc;
using DataConnector;
using DevExpress.Web.ASPxGridView;
using DevExpress.Web.Data;
namespace Sample.Views.Actions
{
public partial class Sample: ViewPage
{
private DataTable dt;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
grid.DataBind();
grid.RowValidating += new ASPxDataValidationEventHandler(grid_RowValidating);
if (!this.IsPostBack)
{
GridViewCommandColumn c = new GridViewCommandColumn();
grid.Columns.Add(c);
c.Caption = "Operations";
c.EditButton.Visible = true;
c.UpdateButton.Visible = true;
c.NewButton.Visible = true;
c.DeleteButton.Visible = true;
c.CancelButton.Visible = true;
}
}
DataTable BindGrid()
{
DataConnection DM = new DataConnection();
if (DM.login("ADMIN", "PASS"))
dt = DM.getDataSet("SELECT * FROM Table_Name");
grid.DataSource = dt;
dt.PrimaryKey = new DataColumn[] { dt.Columns[0] };
return dt;
}
protected void grid_DataBinding(object sender, EventArgs e)
{
// Assign the data source in grid_DataBinding
BindGrid();
}
protected void grid_RowUpdating(object sender, ASPxDataUpdatingEventArgs e)
{
int id = (int)e.OldValues["id"];
DataRow dr = dt.Rows.Find(id);
dr[0] = e.NewValues[""];
dr[1] = e.NewValues[""];
dr[2] = e.NewValues[""];
dr[3] = e.NewValues[""];
dr[4] = e.NewValues[""];
ASPxGridView g = sender as ASPxGridView;
UpdateData(g);
g.CancelEdit();
e.Cancel = true;
}
void grid_RowValidating(object sender, ASPxDataValidationEventArgs e)
{
int id = (int)e.NewValues["id"];
if ((!e.OldValues.Contains("id") || ((int)e.OldValues["id"] != id))
&& (dt.Rows.Find(id) != null))
{
ASPxGridView grid = sender as ASPxGridView;
e.Errors[grid.Columns["id"]] = String.Format("Column 'Id' is constrained to be unique. Value '{0}' is already present.", id);
}
}
private void UpdateData(ASPxGridView g)
{
g.DataBind();
}
}}
The Sample is called on the controller page:
[C#]
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Data;
using DataConnector;
namespace Sample.Controllers
{
public class ActionsController : Controller
{
public ActionResult Sample()
{
return View();
}
}
}
The data displayed on the Grid.
I created a new solution where is only the Sample.aspx and Sample.aspx.cs and I'm using without MVC and the functions are working. The difference is "public partial class Sample: System.Web.UI.Page ".
If I try without System.Web.UI.Page on my mentioned code it gives me the following error:
The view must derive from ViewPage, ViewPage<TModel>, ViewuserControl,or ViewuserControl<TModel>.
What am I doing wrong? Why does not the function of the ASPxGridView working?
I'm sorry in advance if it is poorly drafted but not my mother tongue is English, and I am a new programmer :)

The ASPxGridView is a WebForms control and cannot be used within ASP.NET MVC. Instead you should use the DevExpress MVC extensions. Specifically, the DevExpress MVC GridView extension
