Handling FormCreated

RadScheduler's FormCreated event allows you to access elements on the advanced form. This is achieved using the FindControl method of e.Container and passing as an argumentthe last part of the renderedcontrol's ID. For example, to access the advanced controls' panel, you need to use e.Container.FindControl("AdvancedControlsPanel").

scheduler Advanced Panel

To find a resource RadCombobox, use the following convention - Res[NameOfResourceType]. For example -e.Container.FindControl("ResUser").

To find a custom attributes RadTextBox, use the following convention - Attr[CustomAttributeName].For example - e.Container.FindControl("AttrAnnotations").

Here are some examples:

Change the start time picker options

C#
protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
{
	if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))
	{
		RadTimePicker startTime = e.Container.FindControl("StartTime") as RadTimePicker;
		startTime.TimeView.StartTime = new TimeSpan(5, 0, 0);
		startTime.TimeView.Interval = new TimeSpan(0, 15, 0);
		startTime.TimeView.EndTime = new TimeSpan(22, 0, 0);
		startTime.TimeView.Columns = 4;
		startTime.TimeView.DataList.DataSource = null;
		startTime.DataBind();        
	}
}

Update the end date picker when the start date picker is changed

C#
protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
{
	if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))
	{
		RadDatePicker startDate = e.Container.FindControl("StartDate") as RadDatePicker;
		if (startDate != null)
		{
			startDate.ClientEvents.OnDateSelected = "changeEndDate";
		}
	}
}
JavaScript
<script type="text/javascript">    
	
	function changeEndDate(sender, e) {
		var endDatePickerID = sender.get_id().replace("StartDate", "EndDate");
		var endDatePicker = $find(endDatePickerID);
		endDatePicker.set_selectedDate(sender.get_selectedDate());
	}

</script>

UPDATE THE END TIME PICKER WHEN THE START TIME PICKER IS CHANGED

C#
protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
{
	if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))
	{
		RadTimePicker startTimePicker = e.Container.FindControl("StartTime") as RadTimePicker;
		if (startTimePicker != null)
		{
			startTimePicker.ClientEvents.OnDateSelected = "changeEndTime";
		}
	}
}
JavaScript
<script type="text/javascript">
  
	function changeEndTime(sender, e) {
		var endTimePickerID = sender.get_id().replace("StartTime", "EndTime");
		var endTimePicker = $find(endTimePickerID);
		var startTime = sender.get_selectedDate();
		startTime.setHours(startTime.getHours() + 1);
		endTimePicker.set_selectedDate(startTime);
	}
</script>

Find the textbox for the annotations custom attribute and change its label

C#
protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
{
	if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))
	{
		RadTextBox attrAnnotationsTextbox = (RadTextBox)e.Container.FindControl("AttrAnnotations");
		attrAnnotationsTextbox.Label = "Notes: ";
	}
}

Add a new combobox that updates the subject field

C#
protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
{
	if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))
	{
		RadComboBox subjectChanger = new RadComboBox();
		subjectChanger.Items.Add(new RadComboBoxItem("-"));
		subjectChanger.Items.Add(new RadComboBoxItem("Homework"));
		subjectChanger.Items.Add(new RadComboBoxItem("Test"));
		subjectChanger.Items.Add(new RadComboBoxItem("Final exam"));
		subjectChanger.Label = "Update subject:";
		subjectChanger.OnClientSelectedIndexChanging = "OnClientSelectedIndexChanging";
		RadTextBox subject = e.Container.FindControl("Subject") as RadTextBox;
		subject.ClientEvents.OnLoad = "OnLoadSubjectTextBox";
		subject.Parent.Controls.Add(subjectChanger);
	}
}
JavaScript
<script type="text/javascript">
  
	var subjectTextBox;
	function OnLoadSubjectTextBox(sender) {
		subjectTextBox = sender;
	}
	function OnClientSelectedIndexChanging(sender, args) {
		subjectTextBox.set_value(args.get_item().get_text());
	}
 </script>

Replace Subject field textbox with a RadComboBox

ASP.NET
<style>
    .hidden-textbox {
        display: none
    }
</style>
<script type="text/javascript">

    var subjectTextBox;
    function OnLoadSubjectTextBox(sender) {
        subjectTextBox = sender;
    }
    function OnClientSelectedIndexChanging(sender, args) {
        subjectTextBox.set_value(args.get_item().get_text());
    }
</script>
C#
protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
{
    if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))
    {
        RadComboBox subjectChanger = new RadComboBox();
        subjectChanger.Items.Add(new RadComboBoxItem("-"));
        subjectChanger.Items.Add(new RadComboBoxItem("Homework"));
        subjectChanger.Items.Add(new RadComboBoxItem("Test"));
        subjectChanger.Items.Add(new RadComboBoxItem("Final exam"));
        subjectChanger.Label = "Update subject:";
        subjectChanger.OnClientSelectedIndexChanging = "OnClientSelectedIndexChanging";

        subjectChanger.Width = Unit.Pixel(250);
        subjectChanger.LabelCssClass = "rfbLabel";

        var item = subjectChanger.FindItemByText(e.Appointment.Subject);
        if (item!=null)
        {
            item.Selected = true;
        }

        RadTextBox subject = e.Container.FindControl("Subject") as RadTextBox;
        subject.WrapperCssClass = "hidden-textbox";
        subject.ClientEvents.OnLoad = "OnLoadSubjectTextBox";
        subject.Parent.Controls.Add(subjectChanger);
    }
}

Hide the "all day checkbox"

C#
protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
{
	if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))
	{
		CheckBox allDayCheckbox = (CheckBox)e.Container.FindControl("AllDayEvent");
		allDayCheckbox.Style.Add("visibility", "hidden");
	}
}

Change the selected index of a resource combobox so always one option is preselected

C#
protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
{
	if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))
	{
		RadComboBox resourceRoomCombo = e.Container.FindControl("ResRoom") as RadComboBox;
		if (resourceRoomCombo.SelectedIndex == 0)
		{
			resourceRoomCombo.SelectedIndex = 1;
		}
	}
}

Make changes in the recurrence editor

C#
protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
{
	if (e.Container.Mode == SchedulerFormMode.AdvancedInsert)
	{
		//To find controls in the recurrence editor, you need to first find the recurrence editor.
		RecurrenceEditor recurrenceEditor = e.Container.FindControl("RecurrenceEditor") as RecurrenceEditor;

		//Checks the recurrence checkbox so that the recurrence editor is expanded.
		CheckBox recurreceCheckbox = (CheckBox)recurrenceEditor.FindControl("RecurrentAppointment");
		recurreceCheckbox.Checked = true;

		//Preselects the weekly option.
		RadioButton weeklyRadioButton = (RadioButton)recurrenceEditor.FindControl("RepeatFrequencyWeekly");
		weeklyRadioButton.Checked = true;
		weeklyRadioButton.Style.Add("color", "red");

		//Preselects Sunday for the weekly recurrence rule in addtion to the day for which the appointment will be scheduled.
		CheckBox sundayCheckbox = (CheckBox)recurrenceEditor.FindControl("WeeklyWeekDaySunday");
		sundayCheckbox.Checked = true;
		sundayCheckbox.Style.Add("color", "red");

		//Preselects the 'End after' option
		RadioButton repeatGivenOccurrences = (RadioButton)recurrenceEditor.FindControl("RepeatGivenOccurrences");
		repeatGivenOccurrences.Checked = true;
		repeatGivenOccurrences.Style.Add("color", "red");

		//Sets the 'End after' option to 3. 
		RadNumericTextBox endAfterInput = (RadNumericTextBox)recurrenceEditor.FindControl("RangeOccurrences");
		endAfterInput.Value = 3;
	}
}

Add a new custom validator for the description field

C#
protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
{
	if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))
	{
		CustomValidator validatorForDescription = new CustomValidator();
		RadScheduler scheduler = (RadScheduler)sender;
		validatorForDescription.ValidationGroup = scheduler.ValidationGroup;
		validatorForDescription.ControlToValidate = "Description";
		validatorForDescription.ErrorMessage = "Description should be more than 20 characters!";
		validatorForDescription.ClientValidationFunction = "validationFunction";
		e.Container.Controls.Add(validatorForDescription);
		
	}
}
JavaScript
<script type="text/javascript">
	function validationFunction(source, arguments) {
		if (arguments.Value.length > 20) {
			arguments.IsValid = true;
		} else {
			arguments.IsValid = false;
