I have datepicker user control and run this on load.

In ie6 it loads the page for a couple seconds then it refreshes the page once it finishes loading the javascript.  The below script is run for each calendar.  I have tons of calendars on the page - over 25.

Is there a solution to the page refresh.  In ie7 it doesn't refresh - it just takes longer to load.

string
script = string.Format(@"

var {0}invalidInput = false;

var {0}errmessage = '';

function {0}_ShowDetails()

{{

var pnlName = '{0}_pnlDetails';

var myPanel = document.getElementById(pnlName);

if (myPanel != undefined)

{{

myPanel.style.display='block';

var rfvName = '{0}_rfv';

var ReqValidator = document.getElementById(rfvName);

ValidatorEnable(ReqValidator,true);

}}

}}

function {0}_HideDetails()

{{

var pnlName = '{0}_pnlDetails';

var myPanel = document.getElementById(pnlName);

if (myPanel != undefined)

{{

myPanel.style.display='none';

var rfvName = '{0}_rfv';

var ReqValidator = document.getElementById(rfvName);

ValidatorEnable(ReqValidator,false);

}}

}}

function {0}_OnDateSelected(sender, args)

{{

{0}invalidInput = false;

{0}_ShowDetails();

}}

function {0}_OnError(sender, args)

{{

if (args.get_reason() == Telerik.Web.UI.InputErrorReason.ParseError)

{{

{0}errmessage='Date must be in valid format (mm/dd/yyyy)';

{0}invalidInput = true;

}}

else if (args.get_reason() == Telerik.Web.UI.InputErrorReason.OutOfRange)

{{

{0}errmessage='Date out of range';

{0}invalidInput = true;

}}

alert({0}errmessage);

}}

function {0}_CustomValidate(sender, args)

{{

var customVal = document.all ? document.all['{1}'] : document.getElementById('{1}');

customVal.errormessage = {0}errmessage;

if ({0}invalidInput)

args.IsValid = false;

}}

function {0}_OnBlur(sender, args)

{{

if (sender.GetTextBoxValue() == '')

{{

{0}invalidInput = false;

}}

}}"

, this.ClientID, CustomValidator1.ClientID);

RadDatePicker picker = (RadDatePicker)RadDatePicker1;

RadDatePicker1.DateInput.ClientEvents.OnError =

string.Format("{0}_OnError", this.ClientID);

RadDatePicker1.DateInput.ClientEvents.OnBlur =

string.Format("{0}_OnBlur", this.ClientID);

RadDatePicker1.ClientEvents.OnDateSelected =

string.Format("{0}_OnDateSelected", this.ClientID);

CustomValidator1.ClientValidationFunction =

string.Format("{0}_CustomValidate", this.ClientID);

Hello Jomey,

We are not sure what is causing the behavior you are observing. It will be best if you open a support ticket and attach to it a small runnable sample which reproduces the issue. Thus we will examine it an get back to you with our findings.

Best wishes,
