My goal is mark with frame some "linked" task. When user select one appointment, then linked appointmemts have to be marked with frame.

I have changed the OrientedAppointmentItemStyleSelector.HorizontalStyle - template of AppointmentItem.

<Border

x:Name="CommonStatesVisual"

BorderThickness="3, 3, 3, 3"

CornerRadius="1"

Visibility="{Binding Appointment.LinkedVisibility}">

<Border.BorderBrush>

..................

</Border.BorderBrush>

<Border x:Name="CommonStatesVisualInnerBorder" BorderBrush="OrangeRed" BorderThickness="3" CornerRadius="1"/>

</Border>

So, my problem is refresh the view after changing Appointment.LinkedVisibility property, because only selected Appointment is change the drawing after updating.

P.S. this approach is not applicable for me https://www.telerik.com/forums/need-to-refresh-scheduleview

Can you help me to force redraw for all appointments?

scroll into view after rangechanged

Hi,

I would like to scroll into view on a specific appointment having a start date not in the visible range.

My problem is that the range is correctly changed but the view is not scolled into this appointment.

I perform this action from a command where I reload the itemsource, then set the current date to the appointment start date and finally use : scheduler.ScrollIntoView(this.SelectedAppointment);

Do you have a suggestion on how to make this work?

Best Regards.

RadAutoCompleBox with custom search function

Hi

I have a requirement from my users to be able to type into an autocompletebox and have it suggest results based on multiple values from my business object.

As an example, if the business object looks like this:

public class Client

{

public string Name {get;set;}

public string AccountCode {get;set;}

public string Address {get;set;}

}

I want to be able to tell RadAutoCompleteBox to not only search on the Name field, but also the AccountCode when the user types into the box. The item data template I am showing the user is a stack panel containing both fields, so then they can start typing a value from either field to populate the suggestion box.

If I could provide the control with a search function to use instead of TextSearchPath, that would be ideal. A lamba like this would do the trick:

radacbox.SearchFunction += (client, search_text) => { client.Name.Contains(search_text) || client.AccountCode.Contains(search_text) };

Is there any way to override the default search behavior of the RadAutoCompleteBox?

[Solved] Upgrading 2013Q1 to 2018Q3: GridViewElementExportingEventArgs.Attributes\Styles

Hi,

We are looking into upgrading our Telerik UI for WPF 2013Q1 to 2018Q3.

As part of the POC process I encountered the following blocking issue.

I need to upgrade this code to Telerik UI for WPF 2018 Q3 but wasn't able to do so after consulting the documentation available on the web.

The main issue is converting the removed\obsolete GridViewElementExportingEventArgs.Attributes["border"] and GridViewElementExportingEventArgs.Styles["background-color"] from 2013Q1 to 2018Q3.

Can you help me solve this upgrade blocking issue?

Thanks in advance

01.private static RadDocument CreateDocument(RadGridView grid, PrintSettings settings)

02. {

03. RadDocument document = null;

05. using (var stream = new MemoryStream())

07. EventHandler<GridViewElementExportingEventArgs> elementExporting = (s, e) =>

Crash when removing the DataContext

I have a crash I cannot reproduce in a test program. I'm allowing the user to change the number of maps on the screen from 1 to 4. When switching from 4 maps to 1 map (for example), I remove the DataContext for the maps that will be hidden. I do this because I will still be updating the ViewModel for every map and do not want the map to reflect these changes if it's not visible. This causes an instant crash for maps 3 and 4. Here is the applicable stack trace:

   at Telerik.Windows.Controls.Map.TilesVisualizationLayer.CalculateViewports()
   at Telerik.Windows.Controls.Map.TilesVisualizationLayer.MultiscaleImage_MotionFinished(Object sender, RoutedEventArgs e)
   at System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs)
   at System.Windows.EventRoute.InvokeHandlersImpl(Object source, RoutedEventArgs args, Boolean reRaised)
   at System.Windows.UIElement.RaiseEventImpl(DependencyObject sender, RoutedEventArgs args)
   at System.Windows.UIElement.RaiseEvent(RoutedEventArgs e)
   at Telerik.Windows.Controls.Map.MultiScaleImage.<RaiseMotionFinishedEvent>b__2()

It appears to crash because there is no longer a provider. Whether the map is visible or not makes no difference. Any ideas?

Animated weather images overlayed onto RadMap

I am developing a WPF (MVVM) application for weather forecasts/hindcasts using a RadMap (Bing maps underneath). I am overlaying the weather images using a VirtualizationLayer and all looks good. What I would like to do next is have a further layer with animated arrows depicting the strength/direction of the wind. Along with the weather tile images, I can also source raw data that will give me this info for a specific location. I came across a website that gives a decent example of what I am trying to achieve: https://www.windy.com/?38.307,-128.364,4 There appears to be some web component that is providing this animation. Would this be possible with a Telerik component?

regards,

Grant

[Solved] ToolTip for LineSeries don't show

Hi,
The SDK Tooltip example (Telerik xaml-sdk-master\ChartView\WPF\Tooltip) works fine. But if I change the series from bar to line,
the tooltip will not show again.

Only change one line:
<telerik:BarSeries CategoryBinding="Quarter" ValueBinding="Profit" />
to:
<telerik:LineSeries CategoryBinding="Quarter" ValueBinding="Profit" />

So, how can I show simple tooltip on LineSeries or ScatterLineSeries?

Thanks.
