Create DetailsView from codebehind

I'm new to Asp.net and have looked around for how to do this, but haven't been able to find it.

I would like to create a detailsview entirely from codebehind. This is because I need certain fields to load based on the user's permissions. Also, I would like the ability to edit the detailsview to be only accessible to certain users. Is there a way to do this?

To complete R.C. answer: In dataBinding method, if datasource is not a DataRowView, you may use:

lblID.Text = DataBinder.Eval(dv.DataItem,"CustomerID").ToString();

It works for me. I found it several times on this forum.

This is a very basic implementatation of DetailsView programmatically. This will get you started.

 protected void Page_Load(object sender, EventArgs e)
    {
        DetailsView dv = new DetailsView();
        dv.ID = "MyDv";
        dv.DataSource = GetDataSet(); // returns a dataset filled using Select Query

        TemplateField tf = new TemplateField();
        tf.ItemTemplate = new AddTemplateToDetailsView(ListItemType.Item);

        dv.Fields.Add(tf);

        dv.DataBind();
        placeholder1.Controls.Add(dv);

    }

Class file code to add TemlplateField. <asp:TemplateField>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI.WebControls;
using System.Web.UI;
using System.Data;

public class AddTemplateToDetailsView : ITemplate
{
   private ListItemType _ListItemType;

    public AddTemplateToDetailsView(ListItemType listItemType)
    {
       _ListItemType = listItemType;
    }
    public void InstantiateIn(System.Web.UI.Control container)
    {
        if (_ListItemType == ListItemType.Item)
        {
            Label lblID = new Label();
            lblID.DataBinding += new EventHandler(lblID_DataBinding);
            container.Controls.Add(lblID);    
        }    
    }    
    void lblID_DataBinding(object sender, EventArgs e)
    {    
        Label lblID = (Label)sender;
        DetailsView container = (DetailsView)lblID.NamingContainer;
        lblID.Text = ((DataRowView)container.DataItem)["CustomerID"].ToString();
    }

}

In case you also need to add InsertItemTemplate OR EditItemTemplate, You can create UserControls for the same and add those in Page_Init() as below. The UserControl must Inherit ITemplate .

protected void Page_Init(object sender, EventArgs e)
{
this.DetailsView1.EditItemTemplate = Page.LoadTemplate("UserControlEdit.ascx");
this.DetailsView1.InsertItemTemplate = Page.LoadTemplate("UserControlInsert.ascx");
}
