Issue is present in 2.8.0 also. The commit also removes functions that exists in standard. It would be a good idea to redo a full code review on this one.

git under windows produces unpredictable amount of changes, sorry for so many commits. I need to strip changelog to single line

[Delagen]

Thanks. Sorry I don,t read carefully instriction, that describe separate process for 2 files

Also methods onbeforeprint and onafterprint were moved from Window into WindowEventHandlers which isn't related to Window.
So it's a breaking change in 2.8.
Code

	window.onbeforeprint = beforePrint;
	window.onafterprint = afterPrint;

start failing to compile:
(533,11): error TS2339: Property 'onbeforeprint' does not exist on type 'Window'.
(534,11): error TS2339: Property 'onafterprint' does not exist on type 'Window'.
Please move them back into Window.

@evil-shrike please file a new ticket for that one and will get it fixed.

Issue is still present in TypeScript 2.8.1

I use my worskpace TypeScript version which is 2.8.1 instead of VS Code's version (2.7.2).

@ps04639 You are wrong If you think that author of issue does not read TS docs

[simonprice33]

(window as any).print(); looks to get around the issue but is still not great as when it creates the js file it resolves to window.print()

I am working on the latest available TypeScript via Nuget and the issue is still present today

@simonprice33 What wrong in you answer, and what you expect?

[DevEddy1]

@simonprice33 I believe at the time of posting this, the latest TS version is 2.8.3. If you are using VSCode (currently ships/updates with 2.8.1) - you can update the TS version to the latest with the command "npm install -g [email protected]".

I'm using ts 2.9.1 and still getting this error.

Edit: Intellij is using 2.8.1 internally, which is causing the error. I don't see any way to change which version of typescript it is using internally. I've even told it to use the typescript under node_modules (which is 2.9.1) but the tab on IntelliJ still says "TypeScript 2.8.1".

That said, I am NOT having this issue in 2.9.1

I am using this code snippet to print my PowerBI embedded report using Angular7 and getting following error.

let report = powerbi.get(reportContainer);

//Trigger the print dialog for your browser.
report .print()
.then(function (result) {
console.log(result);
})
.catch(function (errors) {
console.log(errors);
});

Error : [ts] property 'print' does not exist on type 'Embed'

@ChamilaMaddumage try (report as any).print() and see how you get on
