Hi there,

I'm trying to display a range series that is defined by a collection and a gap.

The ObservableCollection is defining the upper limit. The lower limit is defined by the upper limit minus the gap.

For this display I want to use a value converter that returns the lower limit for each upper limit.

 

The SensorParameter struct looks like this:

 

The value converter is implemented like this:

 

UpperLimit binds correctly. But I'm not getting the binding to the lower limit correctly. While debugging the value converter is called, but the arguments are not passed correctly.

Is there a restriction using value converters for the low binding?

 

Thanks in advance for your help.

Kindly

Philipp

I reproduced the "First Look" example program code in "NotifyIcon" in the "NotifyIcon" in "WPF Controls Examples" program in a project created on a personal computer.
It is executed.
However, the popup does not appear when the button is pressed.
If you write the code using the "NotifyIcon" introduced on the "Telerik UI" site, the results are the same.
It runs, but no popup appears.
Simply submit the code you wrote below.
Can you tell me what the problem is?

 

MainWindow.xaml.cs
        private void OnShowNotification(object sender, RoutedEventArgs e)
        {
            this.icon.ShowBalloonTip();
        }

 

MainWindow.xaml

    Button Content="Show notification" Click="OnShowNotification" /> 
    <telerik:RadNotifyIcon 
        x:Name="icon" 
        BalloonText="Balloon Text" 
        BalloonTitle="Balloon Title" 
        TrayIconSource="black.ico" 
        BalloonIconSource="black.ico"> 
    </telerik:RadNotifyIcon> 

 

 

Hello,

In the Windows Explorer, you can change the view using Ctrl+Mouse Wheel.

Your file dialogs should do the same.

Hello,

The following resources are wrong in French:

• FileDialogs_FileSizes_B, should be "octets" instead of "bytes".
• FileDialogs_FileSizes_GB, should be "Go" instead of "GB".
• FileDialogs_FileSizes_KB, should be "ko" instead of "KB".
• FileDialogs_FileSizes_MB, should be "Mo" instead of "MB".
• FileDialogs_FileSizes_TB, should be "To" instead of "TB".
• FileDialogs_OpenFolderDialogHeader, should be "Sélectionner un dossier" instead of "Ouvrir le dossier".
• FileDialogs_OpenFolder, should be "Sélectionner le dossier" instead of "Ouvrir le dossier".
• FileDialogs_DateHeader: should be "Modifié le" instead of "Date de modification ".
• FileDialogs_Back, should be "Précédent" instead of "Retour".
• FileDialogs_Forward, should be "Suivant" instead of "Transférer".
• FileDialogs_Up, should be "Dossier parent " instead of "En haut".
• FileDialogs_CopyTo: should be "Copier sur" instead of "Copier a". (there's a typo in "Copier a", as the "a" must take a grave accent in this case: "à").
• FileDialogs_MoveTo: should be "Déplacer vers " instead of "Déplacer".

Note for English:

• The official SI abbreviation for "kilo" is a lowercase "k", not an uppercase one, so it should be "kb" in English, not KB, and so on.
• For the RadOpenDialogFolder, we don't "open" a folder, but "select" it, This should be changed in the resources, but also in the documentation (and even in the class name!).

It's also strange that the FileDialogs_InvalidOrMissingExtension resource says something completely different: "If you change a file name extension, the file might become unusable". Some thing for the FileDialogs_InvalidExtensionConfirmation resource.

Hello,

In the Windows Explorer, it is possible to use the Alt+Left keyboard shortcut for Back and the Alt+Right shortcut for Forward.

Your file dialogs should do the same.

Is it possible to select an item programatically? After I bind the TreeMap control I would like to select a default item.

Thoughts on what I'm doing wrong here?  If I collapse a ListBoxItem, why does the RadListBox control on partially collapse it?  It still has a height of a couple of pixels when the bound property for visiblity is set to Visibility.Collapsed.

Hi,

I'd like to display data from database using an OData endpoint in the GridView. For this I've decided to use the QueryableDataServiceCollectionView, passing the DataServiceContext and DataServiceQuery into constructor.

For OData, I have a standard setup of Web Api OData Service endpoint and WCF Data Services 5 WPF Client. Model (DTO) looks like this:


And the autogenerated client side counterpart like this:


When loading data into the QueryableDataServiceCollectionView 


I get this error:

System.ArgumentException: The DataServiceCollection to be tracked must contain entity typed elements with at least one key property. The element type 'Edft.Regulatory.Tracker.Presentation.CrossCutting.ServiceClient.ApiODataService.TradeHeaderModel' does not have any key property.
   at System.Data.Services.Client.DataServiceCollection`1.StartTracking(DataServiceContext context, IEnumerable`1 items, String entitySet, Func`2 entityChanged, Func`2 collectionChanged)
   at System.Data.Services.Client.DataServiceCollection`1..ctor(DataServiceContext context)
   at Telerik.Windows.Controls.DataServices.DataServiceCollection`1..ctor(DataServiceContext context)
   at Telerik.Windows.Data.QueryableDataServiceCollectionView`1..ctor(DataServiceContext dataServiceContext, DataServiceQuery`1 dataServiceQuery)
   at Edft.Regulatory.Tracker.Presentation.Modules.Dashboard.ViewModels.TradeHeaderViewModel.<LoadDataAsync>d__1f.MoveNext() in d:\TFS\Regulatory\Tracker\Dev\Codebase\Edft.Regulatory.Tracker.Presentation.Modules.Dashboard\ViewModels\TradeHeaderViewModel.cs:line 272

Note that the DataServiceKeyAttribute is defined on both client and server models.

Any ideas? 


Edit: Using the Telerik.Windows.Controls.DataServices50 version

Thanks,
Stevo

I'd like to be able to use a masked input control to allow the user to enter a hexadecimal number representing a color value (ARGB) e.g. #FF445566 or 0x445566. Is there some way I can use one of the mask controls to achieve this?

Thanks
Pete

 

I know that it is possible to remove distinct values from the filters, as described in this article: https://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/how-to/howto-display-all-distinct-values

But I want to add distinct values to the column filter. The use case would be when the user is creating a favorite for a specific set of filters. When the user comes back later to the list, it may not contain the values that the favorite filter had specified at that moment. But the user would like to still be able to see what the filters for the favorite looks like.

Is it possible to add distinct values to a column filter, without creating a custom filter editor?
