Is it flickering during update only?

yes it only gives the problem when update. i have binded the values in following manner

Server side code on checkBox click
protected void chkClinicList_SelectedIndexChanged(object sender, EventArgs e)
{
DayPilotCalendar1.DataSource = fnGetRecordsBasedOnCritria(strDoctorId, strClinicListId);
DayPilotCalendar1.DataBind();

DayPilotCalendar2.DataSource = fnGetWaitingRecordsBasedOnCritria(strDoctorId, strClinicListId);
DayPilotCalendar2.DataBind();

UpdatePanel1.Update();
UpdatePanel2.Update();
}

If you place the Calendar inside an UpdatePanel it gets redrawn completely during update. Different browsers may be able to handle it differently (IE is not very good at smooth redrawing). The page layout may also have some influence (you can try it with a plain page).

I would recommend switching to CallBack updates. Even full update doesn't redraw everything so it will be faster and smoother.

See also here (this doc page is for Scheduler but you can use the same mechanism with Calendar):

I have to filter the data in the calender based on the check boxes clicked.
Can you tell me how to do that using commandcallback. based on the check on the checkbox.

Thanks in advance
