Hi everyone,

I would like to customize the AppointmentDialog and the RecurrenceDialog in same time but I have a problem.

So, I made in two ResourceDictionary a ControlTemplate foreach Dialog.

• <ControlTemplate x:Key="EditAppointmentTemplate" TargetType="telerik:SchedulerDialog">...</ControlTemplate >
• <ControlTemplate x:Key="EditRecurrenceTemplate" TargetType="telerik:SchedulerDialog">...</ControlTemplate >

After that, I create another ResourceDictionary where I define the Styles :

•                     <Style BasedOn="{StaticResource EditRecurrenceDialogStyle}" TargetType="telerik:SchedulerDialog" x:Key="EditRecurrenceDialogStyle">
                          <Setter Property="Template" Value="{StaticResource EditRecurrenceTemplate}"/>
                      </Style>
•                     <Style BasedOn="{StaticResource EditAppointmentDialogStyle}" TargetType="telerik:SchedulerDialog" x:Key="EditAppointmentDialogStyle">
                          <Setter Property="Template" Value="{StaticResource EditAppointmentTemplate}"/>
                      </Style>

Then, in the telerik:RadScheduleView I set the proprieties in the following way :

•             <telerik:RadScheduleView
                                      ...
                                      AppointmentsSource="{Binding Appointments}"
                                      EditRecurrenceDialogStyle="{StaticResource EditRecurrenceDialogStyle}"
                                      EditAppointmentDialogStyle="{StaticResource EditAppointmentDialogStyle}"
                                      ...>

When I test the styles individually it works. However when I test with both styles define, I have this error:

• ArgumentException: Item has already been added. Key in dictionary: 'Telerik.Windows.Controls.SchedulerDialog'  Key being added: 'Telerik.Windows.Controls.SchedulerDialog'

How can I fix that ?
Thanks in advance for your help.

If I use a TabControl with the Fluent theme and switch to the dark mode then the header of the control does not switch to dark theme properly.

The background seems transparent and the header content is not visible.

Version 2018 R3

See really simple sample project attached (renamed zip to jpg ;) ).

i have two problems in using map control in right to left

i am using a custom map tile provider

the flow direction of my application is right to left when i open the map control my map tiles are mirrored all the streets and texts and ... are reverse as if i have put the image in front of a mirror. to relieve that issue i put the flow direction of the rad map to left to right. now i have my second problem! when i want to export the map view as a png file the exported file is mirrored!

is this a known issues or am i doing something wrong ?

thx in advance for your help

     Hi there,

I want to be able to show symbol shapes in the toolbox but create the actual shapes when it is dropped on the diagram. right now gallery items accept a shape but cant change the appearance of it. style templates didnt work either. any idea how to do this ?

Hello,

I'm getting a Dictionnary exception when using the Import function of the RtfFormatProvider in a Task.

Here's an example of the code that is run:

I'm loading items in parralel using Tasks.

Those items have a property bound to a RichTextBox and I'm deserializing the RTF string in a RadDocument through a RtfFormatProvider.

The code worked fine when I didn't use the Tasks and called the function in a synchronous way. However, since I switch to Tasks, I get the follwing error on the Import method:

"An item with the same key has already been added"

(PS: The code has been tested with the latest release of UI for WPF)

I don't suppose the RtfFormatProvider has a hidden ConcurrentDictionary somewhere that could solve this? :)

Do you know if what I'm trying to acheive is possible?

I am saving the layout using the savelayout method on the docking control.

This works fine (although i have no pane titles but that is another question) until I float panes on external monitors (I have 3). 

When I do this and I use the save layout method I get an error 'Managed Debugging Assistant: 'FatalExecutionEngineError'. The runtime has encountered a fatal error. The address of the error was at 0x65bf395f, on thread 0x4548. The error code is 0x80131623. This error may be a bug in the CLOR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.

My code (in the Window closing event) is:

MemoryStream stream = new MemoryStream();
DockMain.SaveLayout(stream);

stream.Seek(0, SeekOrigin.Begin);

StreamReader reader = new StreamReader(stream);

var layout = reader.ReadToEnd();

Then i persist layout to a file.

Can you please assist.

Hi,

Based on this ( https://www.telerik.com/forums/cannot-implicitly-convert-type-radwindow-to-window )

i tried to get the HostWindow in an mvvm + prism with prismapplication.

But it failed in CreateShell() the Shell is a RadWindow and is created but there is no HostWindow retuned and so it will not work.

Maybe because in PRism the changed the return Type to Window ( i think it was DependencObject before ) 

but so what can i do to return the Shell here ? 

thanks br

thomas

protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
    containerRegistry.RegisterSingleton<ShellWindow>();
}
 
protected override Window CreateShell()
{
    var shellwin = Container.Resolve<ShellWindow>();
    var appwin = Window.GetWindow(shellwin);
    return appwin;
}

I want to be able to toggle between the different orientations of the schedule view. I have a property bound to my view model but this doesn't seem to be working. I have tried different variations. Can someone tell me what i may be missing?
