Add ComboBox in AppointmentDialog

[Satyendra]

I am getting issues in populating ComboBox in AppoinmentDialog window.
I got EditAppointmentDialogStyle source code from RadScheduleView template and edited its EditAppointmentTemplate
I am trying to load Exceptions list in comobox. ExceptionList contains collection of ResourceException type.

<telerik:RadComboBox x:Name="cmbException" Grid.ColumnSpan="2" Grid.Column="1" Grid.Row="0" ItemsSource="{Binding ExceptionList}" Width="210"

SelectedItem="{Binding Occurrence.Appointment.ResourceException, Mode=TwoWay}"/>     

ViewModel is populating ExceptionList but ComboBox is showing nothing, Not sure the way binding to SelectedItem property. Need your help to show data in combobox
Please share code sample how to load data in combobox.

Hello Satyendra,

I guess that ExceptionList is a property in your ViewModel used to bind the ScheduleView. But the DataContext of the EditAppointmentDialog is an AppointmentDialogViewModel object -  that's why the binding doesn't work.  In this case you should bind the combobox like this:

<telerik:RadComboBox x:Name="cmbException" Grid.ColumnSpan="2" Grid.Column="1" Grid.Row="0" ItemsSource="{Binding ElementName=ScheduleView, Path=DataContext.ExceptionList, Mode=TwoWay}" Width="210"  SelectedItem="{Binding Occurrence.Appointment.ResourceException, Mode=TwoWay}"/>

where ScheduleView is the name of the control:

<telerik:RadScheduleView x:Name="ScheduleView"
AppointmentsSource="{Binding Appointments}"
EditAppointmentDialogStyle="{StaticResource EditAppointmentDialogStyle}">

...

Hope this helps.

Only thing I added is to show Description property in ResourceException class to display in combobox.
DisplayMemberPath="Description"

 Thanks

<telerik:RadComboBox x:Name="cmbException" Grid.ColumnSpan="2" Grid.Column="1" Grid.Row="0"  Width="250"
                    ItemsSource="{Binding ElementName=radSchedule, Path=DataContext.ExceptionList, Mode=TwoWay}"
                                         DisplayMemberPath="Description"
                                         SelectedValuePath="AttendCode"
                                         SelectedItem="{Binding Occurrence.Appointment.ResourceException, Mode=TwoWay}"
                                         SelectedValue="{Binding Occurrence.Appointment.Subject, Mode=TwoWay}"     />

After upgrading to Telerik Q2 release dlls, above code is not populating data in ComboBox. It was working perfect with Q1 dlls.

That might be because of error I am getting in RadSchedulerView templates in  <UserControl.Resources> after upgrading to Telerik Q2 release dlls.
Error 7 Ambiguous type reference. A type named 'InvertedBooleanConverter' occurs in at least two namespaces, 'Telerik.Windows.Controls' and 'Telerik.Windows.Controls'. Consider adjusting the assembly XmlnsDefinition attributes.

Hi,

same problem for me after upgrading to the last version of telerik silverlight components :

• If i remove in my page ressources

<telerik:InvertedBooleanConverter x:Key="InvertedBooleanConverter"/>

the design of my page is well displayed in visual studio but an error occurs when trying to open a appointment dialog (double click on an appointment)

• if i let this, the designer in visual studio doesn't display the page saying the error mentionned by Satyendra (Ambiguous type reference. A type named 'InvertedBooleanConverter' occurs in at least two namespaces, 'Telerik.Windows.Controls' and 'Telerik.Windows.Controls'), but my application works well

My page contains essentially the entire template of radscheduleview (generated by blend), there is a change of this template in last version ?

Also the telerik components are not anymore in my toolbox after the upgrade, but this may be another problem and put in another thread.

Hi Maxence,

To solve the issue I suggest you change the line as follows:
OLD

<telerik:InvertedBooleanConverter x:Key="InvertedBooleanConverter"/>

NEW

<schedule:InvertedBooleanConverter x:Key="InvertedBooleanConverter"/>

where:
xmlns:schedule="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.ScheduleView"

All the best,
