I have a rad cartesian chart that displays temperature data that are fed at 1s interval.

There are several series. 

After about 5-10min, the UI becomes slow and unresponsive. I've tried several render option, Xaml, Bitmap & Direct2DRenderOptions with Batch mode but it still being an issue.

It doesn't seem to happen using scatter series, but then I cannot format the time label on the C

How can I improve performances?

Hello,

i was in correspondence with Martin Ivanov and we worked out some information i want to share.

Situation: Multi-Monitor-Environment with Taskbars on every monitor. Docking with floating panes and taskbar icon like: https://github.com/telerik/xaml-sdk/tree/master/Docking/FloatingPaneTaskbarIcons 

Problem: when moving a ToolWindow to the next monitor the taskbar icon stays on the monitor it was created.

Reason: some native WPF window behavior

Workaround: Create a custom ToolWindow and "refresh" icon when window is moved to an other monitor:

I hope this helps. If someone optimize the code and find a solution to prevent the flickering on "refresh" please share it!

regards marco

Hi, I'm developing an RadWizard page with RadBusyIndicator control.
I've got the busy indicator that inside have the RadWizard so I have one busy indicator for all wizard pages.
At last page of wizard I've got an input and I would to set focus to it when the busy indicator finish. But it don't happen.
I've try the solution with FocusHelper.EnsureFocus but nothing happens.

I reproduce the case and attach the project here: https://we.tl/t-nPCbEFRtjw
How can I do this?
I notice that if the BusyIndicator is in WizardPage.Content than all work as aspected.
Thanks

Hello,

Is there a way to change the default behavior of hyperlinks within a RichTextBox to allow file:/// links? After inserting a link through the UI, the control seems to automatically add the 'http://' to an address that begins with the file:/// scheme.

Hey everyone,

I'm looking to have a RadGridView's horizontal scroll bar react to a trackpad or mouse wheel input. Vertical scrolling works just fine, but is there a way to set it for horizontal as well? I know some apps have that functionality only when the user has the mouse hovered over the scroll bar.

Is this possible? Did I miss a setting somewhere?

Thanks!

Hi, I need to create the both types of windows Transparent and non Transparent. The RadPane pane.DataContext  contains appropriate information about the type of window to be created for this RadPane.

I see in https://www.telerik.com/forums/hosting-a-win32-window-in-a-wpf-floating-tear-off-tab that it was impossible in 2012, but may be do you have any updates for this issue?

How I can implement this?
Thanks

I have a problem in the runtime application with the theme , in fact, I didn't get the same format that was displayed in the xaml designer .

the problem is related to the undo button as you can see in the attachments .

How can I fix this problem of design?

Hello,

I'm using RadRichTextBoxRibbonUI and it works fine , but I have a little suggestion about tab items. Is it possible to add a text ( "File" ) to the tab item file name ( as an example the theme existed in Document Text in OneDrive )? . See the attachments 

Hello.

I saw the post in 2013. At that time, it was impossible to implement.

Is it possible now? Putting something like "ItemsSource={bindg WorkBook}" in telerik:RadSpreadsheet and binding it with MVVM?

Even when called like this, a workbook and a worksheet are created and bound in the viewmodel, and modifications should be possible afterwards.

About 8years have passed. But there are not many posts.

If possible, ask for examples. Thanks.
