Is there a way to change the Fluent Colours while the application is running? I can change the colours to custom colours using FluentPalette.Palette.MainColor during the constructor of my rad window, but it doesn't seem to have an effect if I try and change them while the application is already running (to let the user pick their colour theme).

I'm adding objects of different types to a virtualization source during the MapItemsRequest call. I'm now trying to format them differently based on their DataType. With a normal control, I can do this:

<Window.Resources>
    <DataTemplate DataType="{x:Type local:Dog}">
        <StackPanel>
            <TextBlock Text="{Binding Path=Name}" Background="Green" />
        </StackPanel>
    </DataTemplate>
    <DataTemplate DataType="{x:Type local:Cat}">
        <StackPanel>
            <TextBlock Text="{Binding Path=Name}" Background="Red" />
        </StackPanel>
    </DataTemplate>
</Window.Resources>
<Grid>
    <ListBox Width="400" Margin="10" ItemsSource="{Binding ListItems}" />
</Grid>

 

However when using a VisualizationLayer, nothing happens. It seems to be unable to select my templates. Do I have to create template selector in code? I was trying to do everything in XAML.

In my VB.Net WPF application I am creating a CartesianCustomLineAnnotation using code behind.  This is working well.

I have not been able to figure out how to display some type of marker (round circle) at the Start and End point of the Custom Line Annotation.  Can anyone provide a recommendation how to achieve this functionality?

Thanks in advance.

Hi

I need to display some alerts (4-5 at a time);
The alerts are displayed correctly, only that during the hiding phase it blocks the whole program.
here is the code (example):

private void DisplayToastForPinUp(int userId)
        {

            RadDesktopAlertManager manager = new RadDesktopAlertManager();
            manager.CloseAllAlerts();
            manager.AlertsReorderAnimationDuration = 1000;
            var pinups = pinUpService.GetAllByUserIdAndDateToRemembre(userId,DateTime.Now);
            foreach (PinUp pinUp in pinups)
            {
                var alert = new RadDesktopAlert();
                alert.Header = "Post: " + pinUp.Title.Trim(); ;
                alert.Content = pinUp.MemoText;
                alert.ShowDuration = 3000;
                manager.ShowAlert(alert);
            }
        }

 

how can I solve it?
thank you

Hello,

I wrote a simple WPF application which uses Telerik's (2016.1.217.45) RadPane.

The pane contains a User control.

This user control contains a LED image. 

When the user control is displayed without pane, the image is OK.

But - When the user control is displayed inside a pane, the image is cut off at its left side.

Can you please help ?

How can I attach a zip with the project ?

Thank you,

Zvika

Hi,

I need to dynamically modify the date and time format displayed by a RadDateTimePicker, in the InputBox and the Clock view.

I am able to change the format of the date and time displayed in the Input box using this code:

                    var culture = new CultureInfo("en-US"); // or "fr-FR"
                    var dtfInfo = new DateTimeFormatInfo();
                    dtfInfo.ShortDatePattern = "M/d/yyyy"; // or "yyyy-MM-dd" for fr-FR
                    dtfInfo.LongDatePattern = "M/d/yyyy";  // idem
                    dtfInfo.DateSeparator = "/"; // "-" for fr-FR
                    dtfInfo.ShortTimePattern = "h:mm tt"; // HH:mm for fr-FR
                    dtfInfo.LongTimePattern = "h:mm tt"; // idem
                    dtfInfo.TimeSeparator = ":";
                    culture.DateTimeFormat = dtfInfo;
                    System.Threading.Thread.CurrentThread.CurrentCulture = culture;
                    System.Threading.Thread.CurrentThread.CurrentUICulture = culture;

However, it seems this code has no effect on the format of the time items displayed by the Clock view , opened after the change of date and time patterns.

How to customize the formatting of the time items displayed in the Clock ?  

I am testing with either "en-US" or "fr-FR" cultures.

Thx,

Alain

Hello Telerik,

 

I'm using a RadDiagram with a custom template for RadDiagramConnection. The function of this template is to rotate some text linked to the connector.

The following code is the style of my custom RadDiagramConnection :

<Style TargetType="diagramscontrols:RadDiagramConnection" x:Key="RadDiagramConnectionStyle_RotateText">
  <!--<Setter Property="Background" Value="{StaticResource DiagramShape_Connection_Background}"/>
  <Setter Property="Stroke" Value="{StaticResource DiagramShape_Connection_BorderBrush}"/>-->
  <Setter Property="StrokeThickness" Value="1"/>
  <!--<Setter Property="ZIndex" Value="{StaticResource connectionZIndex}"/>-->
  <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
  <Setter Property="VerticalContentAlignment" Value="Stretch"/>
  <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
  <Setter Property="Template">

              </TextBox.InputBindings>
            </TextBox>
          </Grid>
        </Grid>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

 

However, I want that the text will be above of the connector. Moreover, I have some bad behaviors depending on the position of the Connector. I attached a file (arrowTexts) to show you these bad behaviors. Tell me if you want more examples.

 

I want to know if you can help me to find a solution to have the good text position.

 

Thank you very much !

Hello, 

I have a RadTileView that is bound to a list of items, so that the tiles are automatically generated. I need to set the PreviewTileStateChanged and TileStateChanged events on the generated tiles. How can I do this?

 

I can't find any sort of 'tile created' event, and I can't set events in the ItemContainerStyle
