RadTimePicker TimeView incorrect after setting StartTime and EndTime

[Jackie]

A pair of RadTimePickers I have for selecting the beginning and end of a shift are displaying the timeview incorrectly after being enabled and having the starttime and endtime values set. They both show every slot from 12AM to 11:45PM, but starting with 12AM selecting a slot displays the value that SHOULD be seen, 8:30AM in this case, and continues for each subsequent slot in the same manner until the endtime slot, whose correct value is 5:15PM at the 8:45AM slot on the selection view. When the binding event is called a second time, the timeviews for both RTPs are correctly shown, going from 8:30AM to 5:15PM. HTML markup of the RTPs in question as follows, as well as the code-behind for the binding event.

//HTML//
<telerik:RadTimePicker ID="tpStartTime" runat="server" EnableTyping="false" TimeView-Columns="4" TimeView-Interval="00:15:00" Enabled="false"></telerik:RadTimePicker>
<telerik:RadTimePicker ID="tpEndTime" runat="server" EnableTyping="false" TimeView-Columns="4" TimeView-Interval="00:15:00" Enabled="false"></telerik:RadTimePicker>

//C#//
protected void dpOriginalDate_SelectedDateChanged(object sender, Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs e)
    {
        DateTime[] shift = getShift((DateTime)dpOriginalDate.SelectedDate);
        tpStartTime.Enabled = tpEndTime.Enabled = true;
        tpStartTime.TimeView.StartTime = shift[0].TimeOfDay;
        tpStartTime.TimeView.EndTime = shift[1].TimeOfDay;
        tpEndTime.TimeView.StartTime = shift[0].AddMinutes(15).TimeOfDay;
        tpEndTime.TimeView.EndTime = shift[1].AddMinutes(15).TimeOfDay;
    }

 

Page_Load contains Page.DataBind(); which appears to be the cause. Do I have to do without it or is there a workaround?

Hello Jackie,

Calling some general binding commands like Page.DataBind() or Panel1.DataBind() is not a good practice. You could call that these methods to individual controls like RadComboBox or RadListBox. Complex data vizualization controls like RadGrid, RadListView and RadPivotGrid should be bound using their built-in NeedDataSource event handler.

The purpose of the Page.DataBind() was to make the MinDate set in the HTML front end actually work. I have moved it to the code behind to get around the problem.

Hello Jackie,

Some properties require to be set earlier in the page life cycle. You can do that during Page_Init event handler.
