Hi,

I was trying to add a custom field to the EditAppointment dialog of my scheduler. The field is a combobox and I can select a value, but the mapping doesn't work, its always null. Here are some code snippets:

MainForm:

Public Sub New()

InitializeComponent()

AddHandler Me.RadScheduler.AppointmentEditDialogShowing, AddressOf RadScheduler_AppointmentEditDialogShowing

Me.RadScheduler.AppointmentFactory = New AppointmentWithNewFieldsFactory

Me.SchedulerBindingDataSource1.EventProvider.AppointmentFactory = New AppointmentWithNewFieldsFactory

Dim appointmentMappingInfo As AppointmentMappingInfo = TryCast(Me.SchedulerBindingDataSource1.EventProvider.Mapping, AppointmentMappingInfo)

appointmentMappingInfo.Mappings.Add(New SchedulerMapping("CustomField", "CustomFieldDatabase"))

End Sub

Private appointmentDialog As IEditAppointmentDialog = Nothing

Private Sub RadScheduler_AppointmentEditDialogShowing(sender As Object, e As AppointmentEditDialogShowingEventArgs) Handles RadScheduler.AppointmentEditDialogShowing

If Me.appointmentDialog Is Nothing Then

Me.appointmentDialog = New AppointmentWithNewFieldsEditForm()

End If

e.AppointmentEditDialog = Me.appointmentDialog

End Sub

AppointmentWithNewFields Class:

Imports Telerik.WinControls.UI

Public Class AppointmentWithNewFields

Inherits Appointment

Public Sub New()

MyBase.New()

End Sub

Private _CustomField As Integer

Public Property CustomField() As Integer

Get

Return Me._CustomField

End Get

Set(value As Integer)

If Me._CustomField <> value Then

Me._CustomField = value

Me.OnPropertyChanged("CustomField")

End If

End Set

End Property

AppointmentWithNewFieldsEditForm

Imports Telerik.WinControls.UI

Public Class AppointmentWithNewFieldsEditForm

Inherits Telerik.WinControls.UI.Scheduler.Dialogs.EditAppointmentDialog

Public Sub New()

InitializeComponent()

End Sub

Protected Overrides Sub LoadSettingsFromEvent(ByVal ev As IEvent)

MyBase.LoadSettingsFromEvent(ev)

Dim appointmentWithNewFields As AppointmentWithNewFields = TryCast(ev, AppointmentWithNewFields)

If appointmentWithNewFields IsNot Nothing Then

Me.ComboBoxCustomField.SelectedValue = appointmentWithNewFields.CustomField

End If

End Sub

Protected Overrides Sub ApplySettingsToEvent(ByVal ev As IEvent)

Dim appointmentWithNewFields As AppointmentWithNewFields = TryCast(ev, AppointmentWithNewFields)

If appointmentWithNewFields IsNot Nothing Then

appointmentWithNewFields.CustomField= Me.ComboBoxCustomField.SelectedValue

End If

MyBase.ApplySettingsToEvent(ev)

End Sub

Protected Overrides Function CreateNewEvent() As IEvent

Return New AppointmentWithNewFields()

End Function

AppointmentsWithNewFieldsFactory:

Imports Telerik.WinControls.UI

Public Class AppointmentWithNewFieldsFactory

Implements IAppointmentFactory

#Region "IAppointmentFactory Members"

Public Function CreateNewAppointment() As IEvent Implements IAppointmentFactory.CreateNewAppointment

Return New AppointmentWithNewFields()

End Function

#End Region

End Class

What did I wrong? Can anyone help me please?

Thanks + greetings

Can I get the drouped value clicking on the header row?

Hello,

I have a gridview that is grouped by a job number. I have all of the rows collapsed. I can expand a group and click on a row within and get the value of the job number. Is there any way of leaving it collapsed and clicking on the group header row and get the grouped value which is the job number for me? I tried and get the error of Object reference not set to an instance of an object. I assume because the cell for that name is not in the row. Is there a different way to get it?

Thanks,

Warren

Saving / Loading Layouts with ContextMenuStrip

I am using Visual Studio 2013 w/ Telerik 2014.1.402.40 for WinForms. I've been working on implementing the Save / Load layout functionality that comes with the RadGridView and everything is working great with the exception of one thing...

My grid has a System.Windows.Forms.ContextMenuStrip assigned to it. There are various items in the menu that do different things. When I load my grid it works find. If I save a layout, then load it back to the grid, the context menu still appears, but clicking items within it no longer work.

I opened one of the saved layouts and noticed it has a section in it relating to the contextmenustrip, but I don't understand this, or why saving the grid layout would affect the ContextMenuStrip that is assigned to it.

There must be something I'm missing, thanks for any info.

Pinned Summary Row when grouping

Hi,

I'm using a Grid with a summary row that I pin to the bottom:

myGrid.MasterView.SummaryRows[0].PinPosition = PinnedRowPostion.Bottom;

Which works great, but when I group on a column at runtime the summary row is no longer pinned.

Is this possible?

Thanks

Shaun.

Any ideas how to solve this?
