Possible to force SynchronizeProperties on SimpleListViewVisualItem?

I have set up a custom SimpleListViewVisualItem and I would like the display to update when some of my properties change. SynchronizeProperties appears to only be called when I select a different item in the list. Is there a way to force SynchronizeProperties to be called from my code?

RadTreeView - missing API

Hi,

I've downloaded trial version of Telerik controls for WinForms mainly to verify if RadTreeView contains required functionality. After playing around for a while I've noticed that it doesn't have couple of methods that are documented in Telerik site:

1) There's no method to add RadTreeNode to RadTreeNodeCollection using Add() method.
http://www.telerik.com/help/winforms/treeview-working-with-nodes-adding-and-removing-nodes.html

2) There's no method to insert RadTreeNode using index to RadTreeNodeCollection:
http://www.telerik.com/help/winforms/treeview-working-with-nodes-reordering-nodes.html

Is it limitation for trial version or is this functionality removed?

embedded formating strings in gridview

Hello;

Is there a way to embed formatting inside a cell, specifically a header cell?

I have some multiline headers using:
RadGridView1.MasterTemplate.Columns("ShippingDateRange").HeaderText = "Ship Date Range" & vbLf & "Not Before/After"
And it would be great to have the top line "Ship Date Range" be bold or a different color ect.

Thank you so much in advance for any thoughts or how others have addressed this need.

Scatter Plot - Reverse Axis

Hi,

Is it possible to reverse the direction of plot axes?

Eg. plotting depths, zero will be at the top of the plot area.

The primary axis seems to be bound to the x-axis (horizontal axis), eg. in relation to trackball and indicators. Is this correct?

Regards
Brian

Problem with LoadLayout

Hi Guys,

Can you please help me. After upgrading to Telerik Q2 2014 (version 2014.2.715). Every time LoadLayout is called I'm getting this hardcoded message box See attachment:

The value "Telerik.WinControls.Data.SortDescriptor" is not of type "Telerik.WinControls.Data.SortDescriptor" and cannot be used in this generic collection.
Parameter name: value

This only happened when the layout contains Sorted column.

Thanks for any help

Programmatically select the raddocument tab in raddock

Good day,

I am using RadRibbonForm window as my MDI Parent and RadDock AutoMdiDetection = true.
Here is what I am trying to achieve. I do not want to duplicate my window base on the childForm.Text.
Every time the user click a button for form entry, the system will check if the childForm.Text exist in the document tab of raddock.
If it exist, it will focus on that tab, else it will be added in as mdi children.
How to focus on that document tab?

I have explore the raddock properties. ActiveWindow, DocumentArray,and etc are null.

Updating RadScheduler with appointments collected on a background thread

I have a data bound scheduler, with a SchedulerBindingSource:

private void InitiateBookingDataSource()

{

if (_appointmentBookings == null) _appointmentBookings = new BindingList<Booking>();

var dataSource = new SchedulerBindingDataSource();

var mappingInfo = new AppointmentMappingInfo

{

Start = "StartTime",

End = "EndTime",

Summary = "BookingSubject",

Description = "BookingDescription",

BackgroundId = "BackgroundId",

AllDay = "AllDay",

RecurrenceRule = "RecurrenceRule",

Exceptions = "Exceptions",

MasterEventId = "MasterEventId",

Visible = "Visible"

};

mappingInfo.Mappings.Add(new SchedulerMapping("CaseId", "CaseId"));

mappingInfo.Mappings.Add(new SchedulerMapping("PratId", "PratId"));

mappingInfo.Mappings.Add(new SchedulerMapping("InterpretorId", "InterpretorId"));

mappingInfo.Mappings.Add(new SchedulerMapping("BoothId", "BoothId"));

mappingInfo.Mappings.Add(new SchedulerMapping("CaseDesc", "CaseDesc"));

mappingInfo.Mappings.Add(new SchedulerMapping("InterpretorDesc", "InterpretorDesc"));

mappingInfo.Mappings.Add(new SchedulerMapping("BoothDesc", "BoothDesc"));

dataSource.EventProvider.Mapping = mappingInfo;

dataSource.EventProvider.DataSource = _appointmentBookings;

dataSource.EventProvider.AppointmentFactory = rsBookings.AppointmentFactory;

rsBookings.DataSource = dataSource;

}

I use async await to get appointments from the database, and on this background thread I also add the appointments to a binding list.

After this work is done I want to update the scheduler by adding the binding list from the background thread to the scheduler's binding list on the UI thread.

_appointmentBookings = await GetDataAsync(_cancellation.Token);

This doesn't fire the Appointments_CollectionChanged event, and the scheduler is not updated

Is there a way to do this in one go? I've done some investigation, and updating the scheduler one appointment at a time seems to fire the Appointments_CollectionChanged event, but this is very time consuming. Another option is to call the InitiateBookingDataSource() method again, but I don't like that solution either.
