PDF Viewer - Look to find text in pdf document using the non-visual componant

Currently, I use PdfViewer telerik component to load a pdf document and find a text.

Unfortunately, the pdfviewer component does not allow multiple search at the same time because the pdfViewer is not thread safe. So, doing the synchronous search blocks sometimes the user interface (WPF).

Can you tell me if there is another way to find a text in a non-visual component.

I think devExpress has developed a such component that can do this, named: PdfDocumentProcessor

Would you have a similar component, please?

Thank you very much!

Changing Selected Unfocused State Color of TreeViewItem

Hi, I have a radtreeview in my application. The tree node data is being populated from code behind. Its styled based on Office2016 theme which is why it is showing a light gray color when a node is selected and then unfocused (please see attached pic). I want to change this light gray color to the dark blue color of the Office2016 theme but cant figure out how. Here is the Style that is applied:

<telerik:RadTreeView.ItemContainerStyle>

<Style TargetType="{x:Type telerik:RadTreeViewItem}" BasedOn="{StaticResource RadTreeViewItemStyle}">

<Setter Property="VerticalContentAlignment" Value="Stretch"/>

<Setter Property="HorizontalContentAlignment" Value="Stretch"/>

<Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>

<Setter Property="IsEditable" Value="{Binding IsEditable, NotifyOnSourceUpdated=True}" />

<Setter Property="IsSelected" Value="{Binding DataContext.IsSelected, Mode=TwoWay, RelativeSource={RelativeSource Self}}" />

</Style>

</telerik:RadTreeView.ItemContainerStyle>

SelectedAppointment does not work if the Appointment has a RecurrenceRule

Hello Telerik Team

We use the MVVM pattern. In order to be able to handle appointments in the ViewModel, we need to know which appointment is currently selected. If the Appointment has a RecurrenceRule, the binding to the SelectedAppointment Propery doesn't work.

Here is a test project on my OneDrive account: https://1drv.ms/u/s!ApC9hrIinTjDcltMasjw7vSKeAc

How to search items in TreeListView when UI Virtualization is enabled.

I have a RadTreeListView with many rows. I am using UI Virtualization. I use the filter and sort functions in the header of the grid. RadTreeListView.ItemsSource is binding MyTreeViewModel.Items.

Now I want to implement a "search", "search next" and "search previous" function. In many text editors you can do that with F3.

If I search in RadTreeListView.Items there are only expanded items and items that are not virtualized.

If I search in MyTreeViewModel.Items and the grid is sorted and filtered I get too many items and the sorting of the items is wrong.

How can I implement a proper "search next" Funktion?
Is there a sorted, filtered and non virtualized collection between MyTreeViewModel.Items and RadTreeListView.Items?

Special slots that do not last the whole day shouldn't be displayed in the month view

Hello Telerik team

We are in the process of evaluating a schedule control. Now we encountered a problem with ScheduleView. Special slots are displayed correctly in the day and week view, but in the month view it is very unpleasant to cover the whole day with a color of one of the special slots. Special slots that do not last the whole day shouldn't be displayed in the month view.
Is it possible to change this behaviour?

Regards,
Marco

Are the DLLs Installed to GAC?

Hi,

I am setting up a new development machine--brand new install of Windows and Visual Studio. When I install the UI for WPF package, it does not install the assemblies into GAC. They don't show up in the reference manager. However, the Reporting tools for WPF show up fine. Other existing environments that we have on other machines have them installed in GAC and they automatically show up in the references list. Am I missing something?

I am using VS 2017 v15.4.5
