We just tried to update to Telerik UI for WPF, version 2022.3.912.  This caused build errors because the method System.Collections.Generic.ExtensionMethods.GetValueOrNull was defined in two assemblies, Telerik.Windows.Documents and Telerik.Windows.Documents.Flow.

I want show something like the Telerik ExplorerControl in folder-browser mode.  But in my control, I need certain folders are shown with a custom icon /view that will reflect the contents of the folder.   I love all the tree-view functionality of the control and do not want to re-invent all of that.  but I need the main pane to show my view, not Telerik's

Basically when ever a folder contains a file named "scan.yaml" and "image01.png", I want my UI to show the contents of "image01.png" as the folder instead of the regular folder icon.  (My code actually does some background processing to overlay other information on that image sometimes but that's not important for now)

Is this possible or would I need to use my own Tree View?

I thought of a few approaches.  Can you tell me which, if any of these are feasible and which would work best?

1.  Use a ControlTemplate that totally replaces the contents of`PART_MainPane` which is currently this

<historyNavigationPane:FileBrowserTabControl x:Name="PART_MainPane"
        Grid.Column="2"
        SelectedIndex="{Binding ElementName=PART_LayoutConfigurator, Path=SelectedIndex}"
        ItemsSource="{Binding Layouts}"
        ContentTemplateSelector="{StaticResource MainPaneTabControlTemplateSelector}">

 Is it feasible to use a style for ExplorerControl with a ControlTemplate  that completely tears that out and replaces that `FileBrowserTabControl` it with my own control? 

2. Use a ControlTemplate that does not show the MainPane at all and just puts my custom control next to the existing tree view.  My control could then key off its sibling's `CurrentDirectory` property

3. Try to find some way to customize how FileBrowserTabControl shows the folder contents as I described

Would any of these work.

I've attached an image of part of what my control looks like in large-icon mode.  It shows two regular folders and two of the "special" folders that I mentioned

(Also I looked for a question tag for ExplorerControl but could not find one so I tagged "General Discussion")

Hello,

We have a project that currently uses Telerik 2013. We need to gradually upgrade different screens in the system to use Telerik 2022.

How do you recommend we do that? Can we use Telerik 2013 dlls and Telerik 2022 dlls in the same project?

Thanks in advance.

Trying to upgrade my C# WPF application to the latest telerik version using the Upgrade Wizard,

It crash right after starting the upgrade with:

An error occurred while running the wizard.

Error executing custom action Telerik.Windows.WPF.VSX.Actions.MultiProjectUpdateReferencesAction: System.Runtime.InteropServices.COMException (0x80004005): This reference cannot be removed from the project because it is always referenced by the compiler.
   at VSLangProj.Reference.Remove()
   at Telerik.VSX.ProjectConfigurators.ApplicationReferenceManager.RemoveReferences()
   at Telerik.VSX.ProjectConfigurators.ApplicationReferenceManager.UpdateReferences()

   at Telerik.VSX.Actions.MultiProjectUpdateReferencesActionBase`1.Execute(WizardContext wizardContext, IPropertyDataDictionary arguments)
   at Telerik.VSX.WizardEngine.ActionManager.ExecActions()

Tried in VS2019 and VS2022, same results. Installed the latest Telerik extension from the VS Extension market.

I would like to indicate/emphasize cells selected for the action.

Example scenario:

1. select 2 cells in the grid;

2. perform some action after pushing separate button "Process selection";

3. now i need to show those previously selected 2 cells despite of clicks on other grid cells or loosing focus on the grid.

There is another button "View All" which will reset grid and clear all "permanently" selected cells.

Looking for suggestions to implement such behavior. Thinking about changing background color, making cell text bold, disabling cells. Any ideas?

CellStyleSelector sample from xaml_sdk demonstrates a static custom cell selection in columns overriding xaml styles. I need to make it dynamic: select cell, perform action, mark cell as processed, select another cell, process it, unmark previous cell, mark new one as processed.

Thank you,

Gennady

Hi,

My problem it's about Telerik.Windows.Controls.RichTextBoxUI. I'm on the process of upgrading a .NetFramework project to NET6, i've download the demo dlls for .NET6 and i'm setting up a Implicit Style, i've done everything this Link said, i've changed my Telerik UIs References to the NoXaml ones, i've merged the Xaml files and i've put the Office2019 themes on the project.

Now the problem is that RichTextBoxUI.xaml it's failing when compiling because can't find isStringNotEmptyToBoolConverter, and when i open the file, it's full of errors, saying it can find the assembly for Telerik.Windows.Controls.RichTextBoxUI. I'm guessing it's due to a missing DLL, but in \Binaries.NoXaml\WPF60 there's no dll for RichTextBoxUI, only RichTextBox.

Telerik.Windows.Documents.Xaml it's also failing and it's almost the same, failing references to other Documents. references that are not in the \Binaries.NoXaml\WPF60 folder.

It's there a place where i can find these dll? are they diferent for NET6 and i'm making a mistake with the setting of the Themes?

Thanks in advance.

I have documents that when saved as a .docx file and opened in Word, they display correctly.

The same document when viewed in the TK Viewer distorts (moves) the position of the elements of the document.

It is adding space where it should not be and wrapping words where they should be on a single line.

I'm attaching a short screenshot of the document in TK View as well as in Word to show difference. It is happening everywhere in the document, but just this screenshot for brevity.

Is there a setting to force it to render exactly as the display in word? Some way to resolve this?

Hi everyone,

I downloaded yerstaday the testing framework (https://www.telerik.com/try/telerik-testing-framework).

And tried to use it today with a dotnet 6 wpf application and a dotnet 6 xunit test project and it seams that the testing framework has compatibility issues.

Can someone confirm it ?

Hello Telerik Team,

I was wondering how one would implement error bars in a ScatterPointSeries that look similar to this: https://demos.telerik.com/kendo-ui/line-charts/error-bars

There is a very similar question that has been asked before (https://www.telerik.com/forums/how-to-plot-error-bar-for-standard-deviation). Unfortunately, it doesn't look like the feature request mentioned there is going to be implemented anytime soon. As a workaround it was suggested to use a RangeBarSeries with a custom PointTemplate, but that will not work for me, since it is a Cathegorical series and I need to plot the data points at any arbitrary xy coordinate, which is my reason to use the ScatterPointSeries.

I was researching further and found someone mentioning a custom renderer but it seems that is only applicable for windows forms.

I also found this site https://docs.telerik.com/devtools/wpf/controls/radchart/how-to/howto-create-scatter-errorbars-and-boxplot-series but it seems to only work for RadChart and not RadCartesianChart.

Any pointers in the right direction would be greatly appreciated.

Best Regards,
Robin
