Suspected Bug: IAppointment.Copy IAppointment.AppointmentCopyFrom

I have a class that extends Appointment like so:

public class AppointmentTaskVm : Appointment

{

private int _appointmentTaskId;

private bool _isBasketItem;

private int _position;

private int? _taskId;

public int AppointmentTaskId

{

get { return _appointmentTaskId; }

set

{

_appointmentTaskId = value;

OnPropertyChanged("AppointmentTaskId");

}

public bool IsBasketItem

{

get { return _isBasketItem; }

set

{

_isBasketItem = value;

OnPropertyChanged("IsBasketItem");

}

public int Position

{

get { return _position; }

set

{

_position = value;

OnPropertyChanged("Position");

}

public int? TaskId

{

get { return _taskId; }

set

{

_taskId = value;

OnPropertyChanged("TaskId");

}

public override IAppointment Copy()

{

var newAppointment = new AppointmentTaskVm();

newAppointment.CopyFrom(this);

return newAppointment;

}

public override void CopyFrom(IAppointment other)

{

var task = other as AppointmentTaskVm;

if (task != null)

{

AppointmentTaskId = task.AppointmentTaskId;

IsBasketItem = task.IsBasketItem;

Position = task.Position;

TaskId = task.TaskId;

}

base.CopyFrom(other);

}

Dragging the AppointmentTaskVm from a ListBox to the ScheduleView causes the Copy and CopyFrom to fire multiple times. This results in the additional properties in the AppointmentTaskVm to loose thier values.

Subscribing to the AppointmentCreated event of the ScheduleView shows that the new AppointmentTaskVm additional properties are initialised with default values (instead of copying the values from the original AppointmentTaskVm).

Master ComboBox with Detail Grid

I am just starting out, and trying to use data binding to display a parent child relationship.

I need to first have the user select in a ComboBox my List of "Currency" objects and display in a Grid the related "CurrencyRates" collection of the selected currency object

I can see the list of currencies in the combo when I bind the ItemsSource property to the DataContext

<telerik:RadComboBox ItemsSource="{Binding}" DisplayMemberPath="Name" x:Name="cboCurrencyList" />

I am not sure how to get a Grid to show the child collection CurrencyRates.... I've tried the code below but didn't work

Source="{Binding ElementName=cboCurrencyList, Path=SelectedValue}"/>

I am using EF4

Adding custom object to CalendarButtonContent

Hi Telerik,

I've had a somewhat similar thread sometime ago, but here is what I need to do:

Basically what I want to achieve is to add some custom object to the CalendarButtonContent for my DataTemplate to access.

I have created a template selector and finding that the given date is a Holiday, then returning my HolidayTemplate.

public class CalendarButtonTemplateSelector : DataTemplateSelector

{

public override DataTemplate SelectTemplate(object item, DependencyObject container)

{

CalendarButtonContent content = item as CalendarButtonContent;

if (content != null && content.ButtonType == CalendarButtonType.Date)

{

if (CentralCalendarWindow.CalendarViewItems != null && CentralCalendarWindow.CalendarViewItems.Exists(c => c.Date == content.Date))

{

CalendarViewItem calendarViewItem = CentralCalendarWindow.CalendarViewItems.Find(c => c.Date == content.Date);

if (calendarViewItem.IsHoliday)

{

return HolidayTemplate;

}

In XAML I would like my template to achieve something like the following (where CustomText is the object somehow added to the CalendarButtonContent or otherwise referenced):

<DataTemplate>

<StackPanel>

<TextBlock Text="{Binding Text}" />

<TextBlock Text="{Binding CustomText}" />

</StackPanel>

</DataTemplate>

I would be happy if I could somehow from my template just access some custom data outside the scope of the CalendarButtonContent, i.e. some static public data, if this would somehow be possible, but I guess that has not really anything to do with your Calendar control :)

Thanks in advance!
Best regards,
Kasper Schou

Inhereting CalendarButtonContent

Hi Telerik,

This is somewhat a spinoff of my previous thread.

My question here is whether or not it is possible to inherit from the CalendarButtonContent and having RadCalendar use this instead?, i.e. adding a Color property that could be set in code behind when selecting template, then binding to this Color property in the template definition in xaml?

Again, this is a simple example and my real case scenario contains many properties, hence having different templates for each combination of custom properties is not a desired approach.

Any advice what be appriciated :)

Best regards,

Tab navigation in a grid with a button column

Hi,

I've created a button column (using the example in the GridView help file, GridViewColumn & CellTemplace) but I would like to alter the tab navigation behaviour.

Right now it's "Previous Cell -> Button Cell -> Button in button Cell -> Next Cell" and I want "Previous Cell -> Button in button Cell -> Next Cell".

Also when using shift-tab to go backward it's "Next Cell -> Button Cell -> Previous Cell" and I want "Next Cell -> Button in button Cell -> Previous Cell".

Is there any way to do this because it makes keyboard navigation more confusing especially if you want to activate the button by pressing space?

I can't seem to find a way to make this work. I hope you can help me.

Thanks

Select an item in a chart with c#

Hi,

I really love working with the telerik toolkit but I stumbled upon a problem. When I try to select a datapoint via c#, the code executes but nothing happens.

The code I use:

chartarea.SelectItem(index);

When I debug my application, I can see all the necessary data is in my chart but after executing this statement, the SelectedItems property hasn't changed and neither did the chart itself.

Are there any suggestions to do this anyway?

Kind regards,

Michiel
