 {
           
    foreach (Control c in Page.Controls)
        foreach (Control ctrl in c.Controls)

          if (ctrl is TextBox)
 
            ((TextBox)ctrl).Enabled = status;

          else if (ctrl is Button)
    
            ((Button)ctrl).Enabled = status;

          else if (ctrl is RadioButton)

            ((RadioButton)ctrl).Enabled = status;

          else if (ctrl is ImageButton)

            ((ImageButton)ctrl).Enabled = status;

          else if (ctrl is CheckBox)

            ((CheckBox)ctrl).Enabled = status;

          else if (ctrl is DropDownList)

            ((DropDownList)ctrl).Enabled = status; 
 
       else if (ctrl is HyperLink)

        ((HyperLink)ctrl).Enabled = status; 

 }
 private void ClearControls()
    {
        foreach(Control c in Page.Controls)
        {
            foreach (Control ctrl in c.Controls)
            {
                if (ctrl is TextBox)
                {
                    ((TextBox)ctrl).Text = string.Empty;
                }

List<WebControl> wcs = new List<WebControl>(); GetControlList<WebControl>(Page.Controls, wcs) foreach (WebControl childControl in wcs) { if(childControl.CssClass == "required") { // do the } } private void GetControlList<T>(ControlCollection controlCollection, ref List<T> resultCollection) where T : Control { foreach (Control control in controlCollection) { //if (control.GetType() == typeof(T)) if (control is T) // This is cleaner resultCollection.Add((T)control); if (control.HasControls()) GetControlList(control.Controls, ref resultCollection); } }

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
