Report is not displaying IE 10 and above - asp.net-mvc

I've designed an SSRS report in SQL Server 2008 R2. I'm displaying the report in an MVC application using the ReportViewer control.
It is working fine in Firefox and Chrome and below IE10 browsers. However, in IE 10 the report is not getting displayed.
If I changed browser mode to IE10 Compat View in the IE Developer Tools (F12), it is working fine. Please check the attached images:
I have gone through several forum's posts, most of them suggesting to keep an meta tag in master file:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIEX">
where X is the IE Version. Some other forum threads suggests to install Service Pack 2 for SQL Server, which I tried but still no luck.
We can not suggest to end user (some of whom may be non-technical) to change the browser mode in Developer Tools.
Please help me display the report in latest IE browsers (IE10 or above) by default.

I've had a similar problem plaguing me for awhile now, and I've never truly been able to get IE10+ to display a report without using compatibility mode. I did discover a workaround though.
Instead of displaying the report in the Report Viewer, I set the display mode to open the report in another program. It appears that your report could be exported to Excel, so I would set the report to open in Excel.
In c# it would look something like this:
rp.ReportDisplayMode = "Excel";

MVC site not showing correctly on IE11 browser from IIS, it shows correctly when IE11 is called from .NET IDE

My site works ok in Chrome and Firefox but i found some problems on IE11 from IIS (but it shows ok on IE11 when called from .NET IDE). main Menu page shows like this, as if it were taking a wrong Bootstrap version:
This is how the same site looks when called from IDE:
So this only happens on IE11, other browsers show this ok. This uses bootstrap 4.31, MVC 5. I don't think there is a real need to show it here since it doesn't look it's related to code (imo it has to be something IE11 specific) but i can add code in case it's needed.
Thanks!
Fixed, the problem was because the browser was using IE7 compatibility mode. Fixed by adding this in headers:
<meta http-equiv="x-ua-compatible" content="IE=11">

How to troubleshoot application page hung issues in Internet Explorer 11 in Windows 7

we have a Struts 2 application. It has a web page that works fine in all browsers except IE 11. The page hangs while loading and stops responding. How to troubleshoot the page hung issues in IE 11 ? Please give some tips.
You could use a virtual machine to achieve so. Refer to Microsoft virtual machines download page for more information. The only problem is that you will be able to test IE8 as the minimum version. There is a specific VM with Windows 7 and Internet Explorer, so if you can use a VM you will be able to test your app.
Other possible solution is to use IETester, it has some bugs, but you can even download a debug bar for it.
Hope it helps.
Finally, we were able to resolve the hung issue in IE browser. We did the following :
In IE, we opened the F12 Developer Tools and went to the Debugger tab.
Clicked on the page that was getting hung.
In the Debugger tab, it showed the line number that was resulting in error. The error was something like "method not supported". The code was
document.form.submit="post".
Made changes in code to solve the error. I modified tag with property method="post" instead of "get".
This fixed the issue.

Umbraco 7 Content editor randomly hangs when generating thumbnails

Umbraco 7.6.6, running under IIS 8.5 on fully patched Windows Server 2011 R2 Standard, 64bit.
Our content editors notice that often when they create a new article (which has some graphics specified) the system hangs after they try to browse to a different article... or indeed anywhere in the front-end site, too. It only affects them; other users are still able to browse and/or create content.
F12 dev tools shows that browser is pending the result of this type of call:
http://whatever.com/media/1101/thumbnail_pmc-1x2.jpg?width=500&mode=max&animationprocessmode=first
If I try to view that thumbnail without the querystring data, it loads instantly... while the first call is still hanging in it's unresponsive tab:
http://whatever.com/media/1101/thumbnail_pmc-1x2.jpg
DEBUG level Umbraco logs just show this:
2017-10-10 17:02:53,120 [P2816/D6/T57] DEBUG Umbraco.Web.UmbracoModule - Begin request: http://whatever.com/media/1101/thumbnail_pmc-1x2.jpg?width=500&mode=max&animationprocessmode=first.
No errors in the umbraco logs, no errors in IIS logs, nothing in event viewer.
Best I can tell, something is going wonky in the browser. Can anybody please advise on how I can troubleshoot further?
Thanks!

Crystal Report Viewer is not working in Google chrome IE11 and Safari

I have an ASP application and this is my first ever crystal report I am doing. The report seems to be all good when I am looking at the reprot in the design and all the data is fine and perfect. However when I try to show it in my Crystal Report Viewer, the report is displyed blank, without data.
Crystal Report Viewer is not working in Google chrome IE11 and Safari but fine in IE8 and IE9
Report Viewer print issue in Chrome / Mozilla / Safari: A solution where you can print report contents inside Report Viewer in any browser.
In the case of Chrome or Mozilla or in Safari, i can not get print option for Report Viewer to print the report content inside the viewer.How can i solve this.
In my search i found "Crystal Report Viewer fails for browser versions >=10".Is it true?
Is there any solution to resolve it.
Just include SizeToReportContent="true" as shown below
<rsweb:ReportViewer ID="ReportViewer1" runat="server" SizeToReportContent="True"...

Crystal Reports CrystalImageHandler and MVC .NET

I am unable to show images in CR reports. I'm developing a MVC 2 project in VS 2008 with Crystal Reports that comes with it (10.5). Everything works fine, except for images. I can see them in the preview mode within the CR designer, but not when the app is deployed, which means I am loading data OK but something's wrong with IIS and/or routing.
When running the app, images appear with the red cross and if I navigate to the following url directly I get a 404 error.
http://localhost:1234/CrystalImageHandler.aspx
I think my problem is similar to the one here but that workaround doesn't seem to work for me.
I should also comment that I'm using the Areas feature within MVC.
EDIT: Forgot to add: When exporting the report to PDF the images are shown ok.
I don't know much about crystal reports, but is there an Http Handler? If there is and you are running IIS 7 on the live server, is the handler registered in the web.config under both system.web/httpHandlers and under system.webServer/handlers?
I forget to register the handlers under system.webServer/handlers for our IIS 7 server sometimes and we were having a similar issue with the Microsoft Charting Controls.
