JavaScript - Loop around properties of a textbox

var allprops="";
 var count = 0;
 for (var prop in RangeFromTextbox)
 {
     allprops += prop + "=" + RangeFrom[prop] + " \n" ;
     if (count > 20)
     {
         alert(allprops);
         allprops = "";
         count = 0;
     }
     count++;
 }
 alert(allprops);

Ajax Page Methods / Update Panels

Here is a blog post suggesting that UpdatePanels are often used in places where an Ajax Page Method would be better suited, it goes on to give an example of how to use Ajax Page Methods.

ASP.NET AJAX Page Methods

Heres another article with the same idea - Page Methods good, UpdatePanel bad.

Why ASP.NET AJAX UpdatePanels are dangerous

Recursive function through controls

        /// 

        /// Recursive loop through form controls.
        /// 
        private void SetFormDisabled (Control control)
        {
            foreach (Control ctrl in control.Controls)
            {
                if (ctrl is TextBox) 
                {
                    ((TextBox)(ctrl)).Enabled = false;
                }
                else if (ctrl is Telerik.WebControls.RadNumericTextBox)
                {
                    ((Telerik.WebControls.RadNumericTextBox)(ctrl)).Enabled = false;
                }
                else if (ctrl is CheckBox)
                {
                    ((CheckBox)(ctrl)).Enabled = false;
                }
                else
                {
                    if (ctrl.Controls.Count > 0)
                    {
                        SetFormDisabled (ctrl);
                    }
                }
            }
        }
