UWP how to export RadGridView`s content - telerik

I've been working recently with Telerik UI for UWP on a personal app with a RadDataGrid component, but I can not find a method of exporting data to Excel format. Is this implemented the extension methods or the fuctionality was dropped? Could you please guide me about it? Thank you so much!

Currently, the UWP DataGrid doesn't have built-in exporting. We do have it logged in the Feedback Portal, you can add your "upvote" by clicking the Like button.
Side-note:
If you are using the open source version of UI for UWP (i.e. the nuget packages vs the Extensions SDK), StackOverflow is the correct place to ask questions.
If you have a licensed version (trial or paid), then you can submit a support ticket here (directly from the engineering team).
See here for the official support options.

How to check Microsoft PowerApps Portal version number?

I wanted to verify if my PowerApps Portal app was at least version 9.3.2... I tried looking for the Portal version in the Portal Management and the Power Platform Admin Center without success.
After some searching, I was able to view the PowerApps Portal version by using https://<your_portal>.powerappsportals.com/_services/about. Result should be similar to below:
You can go to https://make.powerapps.com/ which will take you to the homepage. Go to the Apps section(left-hand side), you can see all your apps listed. Go to your corresponding app and click on the 3 dots on the right side and from their go-to Details . It opens up a screen, now click on the Versions tab and there you can see all the versions of the app, the current version, and the live version.

How do we integrate system photo editing into our macOS apps?

Multiple third-party macOS apps now have a feature to edit photos, and the UI looks exactly the same as in Preview. How do we implement this functionality? Has a new framework been released?
Including links to screenshots for comparison. Some buttons are not included in the third-party app, but the UI and the behaviour is exactly the same in both apps.
Shotty (3rd party app) image editing controls
Apple Preview image editing controls
Your help would be greatly appreciated, a link to Apple documentation would already be helpful.

How do I get the Compose Extension Ellipsis button to show up with a custom side-loaded Microsoft Teams app?

I'm trying to learn how to create a Microsoft Teams app following their getting started guide:
https://learn.microsoft.com/en-us/microsoftteams/platform/get-started/get-started-nodejs#ComposeRichMessages
Using the source code from here: https://github.com/OfficeDev/msteams-samples-hello-world-nodejs
I also read the specific docs here:
https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/messaging-extensions
I have the app configured and packaged and side-loaded. The tabs and bot are functioning normally. However, the compose extension ellipsis button never shows up.
Supposedly, all I should need to do is set the correct botId in the composeExtensions section of the manifest.json. I did that, but it's still not showing up.
I have no clue how to troubleshoot this.
Thanks!
According to the docs...
Important
messaging extensions are available only in Public Developer Preview. Many details in this document are subject to change.

You might check each component vendor specs as some have been enhanced since the time the article was written (ex : DevExpress PDF component for UWP supports search) BuiltIn PDF component purpose is to render documents, not manipulate. You can contact the dev team for feature requests.

Source for a LoopingSelector for WP7

I have been looking at nice, 3 part series about LoopingSelectors by Win phone Geek and unfortunately there is a missing source link for the first part on that website.
Can someone offer to please mail it to me or paste it in here, because I don't want to reinvent it? I would apppreciate it. Thanks.
Code for other demos for LoopingSelectors would be fine too.
The LongListSelector is part of the Silverlight for Windows Phone Toolkit. You can download the Source & Samples for the November 2010 release, or download the latest version, which includes fixes for various controls to enable applications to pass certification (there were issues with Back key press handling).
