Chage TimeView by code

[Dario]

Hi to all,
I would:

1. select an item by dropbox
2. select a date, and by this auto-postback
3. Into selected-changed event I would change timeview (starttime, endtime and interval)

How can I do this?

Hi Dario,

I suppose you want to change the timeview (starttime, endtime and interval) in SelectedDateChanged Event. Here is the sample code that I tried.

C#:

protected void RadDateTimePicker1_SelectedDateChanged(object sender, Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs e)
{
 TimeSpan start = new TimeSpan(2, 0, 0);
 TimeSpan end = new TimeSpan(10, 0, 0);
 TimeSpan interval = new TimeSpan(2, 0, 0);
 RadDateTimePicker11.TimeView.StartTime = start;
 RadDateTimePicker11.TimeView.EndTime = end;
 RadDateTimePicker11.TimeView.Interval = interval;
}

Hope this helps.

Thanks,
Princy.

I explain my situation:

I have a RadCalendar controllo and RadDropBox.
I have to select an item of RadDropBox, this item gives me some information (starttime, endtime and interval).
After this I select a date on RadCalendar, this controlo has AutoPostBack = true.
Into RadCalendar_SelectDateChanged (I don't remember if this is the name of this event), I must change properties of a RadDateTimePicker.

I done this, but gives me a trange effect: I must click 2 times on RadCalendar because on first time I don't obtain a correctly configuration of RadDateTimePicker.

I don't undestand why this...

Hi Dario,

Unfortunately I couldn't replicate the issue you are facing. Here is the full code that I tried based own your scenario which works as expected.

ASPX:

<telerik:RadComboBox ID="RadComboBox1"  runat="server" >
     <Items>
      <telerik:RadComboBoxItem Text="one" Value="1" />
      <telerik:RadComboBoxItem Text="two" Value="2" />
      <telerik:RadComboBoxItem Text="three" Value="3" />
     </Items>
</telerik:RadComboBox>
<telerik:RadCalendar ID="RadCalendar1" runat="server" AutoPostBack="true" onselectionchanged="RadCalendar1_SelectionChanged" >
</telerik:RadCalendar>
<telerik:RadDateTimePicker ID="RadDateTimePicker1"  runat="server" >
</telerik:RadDateTimePicker>

Please  provide your code if this doesn't helps.

Thanks,
Princy.

Ok thank you for support:

RadCalendar_SelectionChanged(object sender, Telerik.Web.UI.Calendar.SelectedDatesEventArgs e)
{
//Set monday day relative to user selected date
            DateTime selezionato = e.SelectedDates.Count == 1 ? e.SelectedDates[0].Date : DateTime.Today;
            DayOfWeek giornoSettimanaleDiOggi = selezionato.DayOfWeek;
            DateTime lunedì = new DateTime();

            if (giornoSettimanaleDiOggi == DayOfWeek.Sunday)
                lunedì = selezionato.AddDays(-6);
            else
                lunedì = selezionato.AddDays((Convert.ToInt32(giornoSettimanaleDiOggi) - 1) * -1);

            RicercaRadCalendar.SelectedDate = lunedì;

//After Change TimeView of RadDateTimePicker
  CustomTimeView MyItemSelected = ConvertValueToMyItemSelected(FieldDropDownList.SelectedValue);

  RadDateTimePicker.TimeView.StartTime = MyItemSelected.StartTime;
  RadDateTimePicker.TimeView.EndTime = MyItemSelected.EndTime;
  RadDateTimePicker.TimeView.Interval = MyItemSelected.Interval;

}

public class CustomTimeView
{
  TimeSpan StartTime {get;set;}
  TimeSpan EndTime {get;set;}
  TimeSpan Interval {get;set;}
 [..]
}

Hi Dario,

Try the following code to achieve your scenario.

C#:

public CustomTimeView ConvertValueToMyItemSelected(string value)
{
    CustomTimeView data = new CustomTimeView();
    data.StartTime = new TimeSpan(2, 0, 0);
    data.EndTime = new TimeSpan(10, 0, 0);
    data.Interval = new TimeSpan(Convert.ToInt32(value), 0, 0);
    return data;
}
protected void  RadCalendar_SelectionChanged(object sender, Telerik.Web.UI.Calendar.SelectedDatesEventArgs e)
{
    //Set monday day relative to user selected date
     DateTime selezionato = e.SelectedDates.Count == 1 ? e.SelectedDates[0].Date : DateTime.Today;
     DayOfWeek giornoSettimanaleDiOggi = selezionato.DayOfWeek;
     DateTime lunedì = new DateTime();
     if (giornoSettimanaleDiOggi == DayOfWeek.Sunday)
     lunedì = selezionato.AddDays(-6);
     else
     lunedì = selezionato.AddDays((Convert.ToInt32(giornoSettimanaleDiOggi) - 1) * -1);
     RicercaRadCalendar.SelectedDate = lunedì;
     //After Change TimeView of RadDateTimePicker
     CustomTimeView MyItemSelected = ConvertValueToMyItemSelected(FieldDropDownList.SelectedValue);
     RadDateTimePicker1.TimeView.StartTime = MyItemSelected.StartTime;
     RadDateTimePicker1.TimeView.EndTime = MyItemSelected.EndTime;
     RadDateTimePicker1.TimeView.Interval = MyItemSelected.Interval;
}

Thanks,
Princy.

Thank you very much!
I understud that my problem was the "selecting date" and forcing date to relative monday day.

Infact, during this second select I'm creating strange environment.

Then, I set this code only when e.SelectedDates[0] is Monday

//After Change TimeView of RadDateTimePicker
     CustomTimeView MyItemSelected = ConvertValueToMyItemSelected(FieldDropDownList.SelectedValue);
     RadDateTimePicker1.TimeView.StartTime = MyItemSelected.StartTime;
     RadDateTimePicker1.TimeView.EndTime = MyItemSelected.EndTime;
     RadDateTimePicker1.TimeView.Interval = MyItemSelected.Interval;

By this way it's ok!
