I have these objects:

txtb1 top: 150px left:450px
txtb2 top: 270px left:450px
txtb3 top: 390px left:450px

I want to align these objects vertically and that it is inside the lPaneln Panel.

C#

Myglobal.txtb1.Attributes.Add("style", "position: absolute;");
Myglobal.txtb1.Attributes.Add("style", "top: 150px;");
Myglobal.txtb1.Attributes.Add("style", "left:450px;");

        var tbutton1 = new System.Web.UI.WebControls.Button();

        this.Boton1.Controls.Add(tbutton1);

        tbutton1.Click += new EventHandler(tbutton1_Click);


        tbutton1.Width = 80;
        tbutton1.Height = 30;
        tbutton1.Text = "BUTTON";
        tbutton1.Visible = true;

        _Default.bLabel ltitle = new _Default.bLabel();


        ltitle.ID = "Label1";
        ltitle.Text = "MY  PROJECT";


        iLabel.Controls.Add(ltitle);

static variables and ASP.NET don't mix. Storing a control or page instance in a static variable is always the wrong thing to do.
