Hi,

I'm trying to create a customised version of the appointment dialog, which will actually combine some of the functionality of both the EditRecurrence dialog and the EditAppointment dialog.

From the EditActivity dialog all I need is the start date and subject fields along with the save and cancel buttons, and then from EditRecurrence I want a checkbox to enable recurrence functionality, which will enable the recurrence pattern and range of recurrence groups of controls in the same dialog.

What would be the best way to implement this window? I've played around with inheriting EditRecurrenceDialog (partial class frmEditAppointment : EditRecurrenceDialog) but I can't seem to hide the controls I don't want. For example when I try to hide the All Day Event checkbox the "Visible" property is greyed out in the designer/properties window and I can't change it to false.

Given these issues I get the impression I'd be best off creating a new appointment dialog entirely, how should I go about doing this? Ideally I wouldn't want to have to recreate groups of controls like the recurrence pattern or range of recurrence and instead just add/copy them in somehow.

Thanks for your help, Tom.

Hello Tom,

Thank you for writing.

You can inherit the EditAppointmentDialog and open the designer. When I select a specific control its Visible property is editable in the Properties window. Please refer to the attached screenshots. However, chkAllDay RadCheckBox is a little bit specific. In the EditAppointmentDialog.Load event the visibility of the RadCheckBox is set to true again. That is why in order to hide it, you should do it via code in the Load event.

An alternative solution to create a custom edit dialog is to inherit RadSchedulerDialog and implement IEditAppointmentDialog. Thus, you will be able to build the desired design and handle the whole edit operation.

I hope this information helps. Should you have further questions, I would be glad to help.

Hello Tom,

Thank you for writing back.

Inheriting the basic RadSchedulerDialog class and implementing IEditAppointmentDialog interface gives you the opportunity to construct the desired look for the edit dialog. However, you should implement the whole required functionality for this dialog. I would recommend you to download our source code and have a look at the EditAppointmentDialog class. Thus, you can pay attention to the introduced implementation about recurrence functionality and follow similar approach. Simply you can show the desired recurring dialog when a certain button is clicked.

I hope this information helps. If you have any additional questions, please let me know.

Hello Tom,

Thank you for writing back.

Note that by default RadScheduler displays a specific dialog for manipulating recurring appointments. You are describing a custom edit dialog. Hence, it is not possible to come out of the box and you should build it according to your requirements. Feel free to use one of the suggested approaches from my previous posts. Additionally, you can have a look at the Demo application >> Scheduler >> Custom appointment dialog example which is quite useful on this topic.

If you have any additional questions, please let me know.

Hello Aref,

Thank you for writing.

The provided information is not enough for me to replicate the issue locally. Could you please specify the exact steps/code snippet how to reproduce the problem? Feel free to open a support ticket and provide a sample project so we can investigate the precise case and assist you further. Thank you in advance.

I am looking forward to your reply.

Hello Aref,

Thank you for writing back.

In order to change the font for the RecurrenceEditDialog, you can subscribe to the RadScheduler.RecurrenceEditDialogShowing event, iterate all the controls in the RecurrenceEditDialog and apply the desired font:

private void radScheduler1_RecurrenceEditDialogShowing(object sender, RecurrenceEditDialogShowingEventArgs e)

{

RadForm f = e.RecurrenceEditDialog as RadForm;

f.Font = font;

foreach (Control c in f.Controls)

{

c.Font = font;

}

Note that this is just a sample approach and it may not cover all possible cases. It would be necessary to iterate the controls recursively in case you need to apply the font to controls from all levels. Feel free to modify it in a way which suits your requirement best.

I hope this information helps. If you have any additional questions, please let me know.

Hi Aref,

I assume that's because they are children of container controls e.g. RadGroupBox contains other controls like buttons, check boxes, etc. To handle this case you can use the ControlHelper.GetChildControls method to get all controls recursively.

I would even advice to inherit from the EditRecurrenceDialog and introduce the needed modifications there. This will be cleaner solution and will allow for further extension. Here is how this class can look like:

class MyEditRecurrenceDialog : EditRecurrenceDialog

{

private MyEditRecurrenceDialog()

: base(null)

{ }

public MyEditRecurrenceDialog(IEvent appointment)

: base(appointment, null)

{

}

public MyEditRecurrenceDialog(IEvent appointment, ISchedulerData schedulerData)

: base(appointment, schedulerData)

{ }

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

SetFontForControls(this);

}

private void SetFontForControls(Control parentControl)

{

System.Drawing.Font font = new System.Drawing.Font("Consolas", 7);

List<Control> allControls = ControlHelper.GetChildControls<Control>(parentControl, true);

foreach (Control c in allControls)

{

c.Font = font;

}

protected override void ShowRecurrenceSettingsControl(IRecurrenceRuleSettingsControl settingsControl)

{

base.ShowRecurrenceSettingsControl(settingsControl);

SetFontForControls((Control)settingsControl);

}

The override of the ShowRecurrenceSettingsControl method is needed, as some of the controls for the recurrence are created dynamically.

To replace the default dialog with the newly created one, you can use the RecurrenceEditDialogShowing handler, you are already familiar with:

void radScheduler1_RecurrenceEditDialogShowing(object sender, RecurrenceEditDialogShowingEventArgs e)

{

e.RecurrenceEditDialog = new MyEditRecurrenceDialog(e.Appointment);

}

I hope that you find this information useful.

Stefan

Hi Aref,

The headers font is changed on my end with this code. See attached image.

Should you still experience this issue, please send a small sample replicating it and I will look into it.

Hi,

I am not sure why you are observing this behavior. What I can offer is to also set the parentControl.Font in the SetFontForControls method:

private void SetFontForControls(Control parentControl)

{

System.Drawing.Font font = new System.Drawing.Font("Consolas", 7);

parentControl.Font = font;

List<Control> allControls = ControlHelper.GetChildControls<Control>(parentControl, true);

foreach (Control c in allControls)

{

c.Font = font;

}

If this does not work for you, please open a support ticket where you can attach your project so we can investigate the precise behavior.

Hello, Nechama,

When you try editing a recurring appointment you will obtain a popup offering you to choose what to edit: the whole series or the single occurrence. The, the EditAppointmentDialog is shown. The RecurrenceEditDialogShowing event is fired before the EditRecurrenceDialog is shown. This is the appropriate place to replace the default dialog with your custom one by setting the RecurrenceEditDialogShowingEventArgs.Dialog.

I have prepared a sample code snippet for your reference demonstrating how to add a custom menu item and show the custom EditRecurrenceDialog when you right-click an appointment:

private void radScheduler1_ContextMenuOpening(object sender, SchedulerContextMenuOpeningEventArgs e)

{

if (e.Element is AppointmentElement)

{

RadMenuItem item = new RadMenuItem();

item.Text = "Edit Recurrence";

item.Tag = e.Element;

item.Click += item_Click;

e.Menu.Items.Add(item);

}

private void item_Click(object sender, EventArgs e)

{

RadMenuItem item = sender as RadMenuItem;

AppointmentElement a = item.Tag as AppointmentElement;

CustomEditRecurrenceDialog dialog = new CustomEditRecurrenceDialog(a.Appointment.MasterEvent);

dialog.Show();

}

CustomEditRecurrenceDialog customRecurrenceDialog = null;

private void radScheduler1_RecurrenceEditDialogShowing(object sender, RecurrenceEditDialogShowingEventArgs e)

{

if (customRecurrenceDialog != null)

{

customRecurrenceDialog = new CustomEditRecurrenceDialog(e.Appointment);

}

e.RecurrenceEditDialog = customRecurrenceDialog;

}

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Hello, Nechama,

In order to add appointments programmatically, you can use the approach demonstrated in the online documentation: https://docs.telerik.com/devtools/winforms/controls/scheduler/appointments-and-dialogs/working-with-appointments

The EditAppointmentDialog allows you either to create a new appointment or edit an existing one. Please refer to the following help article which also demonstrates how to create a custom EditAppointmentDialog: https://docs.telerik.com/devtools/winforms/controls/scheduler/dialogs/editappointmentdialog

I hope this information helps.
