Telerik image editor Tool Dialog issue - asp.net

I am trying to implement a rad editor. In it there is an Image Manager and inside the image manager is an Image Editor. So far its fine(the image is being shown perfectly).
As in every story there is a villain here it is.
Now the problem arises when i click on any of the tool buttons in the image editor window. The popup screen but there is nothing inside it. Like when i click on the Crop button the popup heading is just Tool Dialog and there is no content in it. A preview can be seen .
This issue is arising only when i use it in a RadEditor. When i am using an Image Manager alone then there is no issue. I am kind of stuck here..
Thanks

This a follow-up, because there is addition information on the issue. The problem is discussed in the following help article: http://www.telerik.com/help/aspnet-ajax/radcompression.html
Known issues
Problem
When RadCompression is enabled and you are using .NET 4.0, event handlers might not be raised in a default document in IIS 7 or IIS 7.5 Integrated Mode.
Solution
This problem is caused by a breaking change in .NET 4.0 described here. To workaround it one can set preCondition="managedHandler" for the RadCompression module. You may also need to remove the runAllManagedModulesForAllRequests setting from your web.config if you have it (or set it to false).

I am aware of this problem which is caused by IIS of Windows 2008 server. The problem arise when the when the loaded URL in the browser doesn't contain the exact page hosting the control.
For example the control will not work at www.domain.com, but it will work at www.domain.com/Default.aspx.
Here you can find article, which discusses such a problem: http://forums.iis.net/p/1175925/1973069.aspx.
Please, note that the issue is not directly related to Telerik controls. If you are unable to solve it you could contact Microsoft or search in Internet for a solution.

Update Panel in web part not working in Google Chrome

I have written a visual web part for SharePoint 2013 in VS2015. The web part contains a number of asp controls as well as a grid view. I implemented AJAX with using script manager proxy and update panel. The deployed web part works well in IE but in google chrome, it doesn't work. I have found the solution on the internet. http://www.jquery2dotnet.com/2011/11/update-panel-not-working-in-google.html. I have put the code in js file in layout folder. In scriptmanager add reference to the file Path="/_layouts/15/prj/WebKit.js". However, it is not working in chrome. Could anyone please tell me how to solve this issue?
There seems to be an issue with SharePoint + UpdatePanel.
I've had the same problem and found the following article:
https://msdn.microsoft.com/en-us/library/ff650218.aspx
To be honest, I couldn't apply the proposed solution, because I couldn't find the requested dll.
So, to solve my postback problem, I saw two possibilities:
1. Use DevExpress
2. Change my code to client side.
I chose the second option.

Compatibility mode IE

I made a lot of research on this topic but none of the found solutions helped me.
So, let's start: I have a VB ASP.NET WEB Application.
The problem is the users can see the source code of the aspx files in the browser (IE) when the Display intranet sites in Compatibility View is unchecked.
I tried all of the methods, settings compatibility from IIS, web.config or even from the meta tags from <head>.
I discovered that also with the checkbox unchecked if I use Enterprise Mode the browser displays the page ok.
I tried then to find a solution to force the Enterprise Mode from code but I didn't find anything without changing registry keys. Changing registry keys can also be done to the above checkbox.
If I go in the DOM Explorere in IE and I try editing the source, anything I delete from there, the page is displayed ok.
How can I force the Enterprise Mode, or the Compatility View Mode from code? or is there another solution for me to solve this problem?
In my opinion you need to check the caching of the application if you say that if you modify something in DOM the page appears.

Ajax toolkit not working properly in IE 10

I have a website in which I have used Asp.net AjaxToolkit modal popup element.
It worked fine on every browser, but recently I tested it on Internet Explorer 10 (on windows 7 platform), and discovered a problem.
When I open a modal popup, the popup content is not loading and a message box is appearing with an error like this:
"Error: Sys.WebForms.PageRequestManagerServerErrorException: Input
string was not in a correct format."
Anyone heard about this error?
What is going wrong, what kind of "Input string" I was prompted about?
Write an answer please, if you know what the problem is.
There is a known problem with ASP.NET and IE10. See Scott Hanselman's blog article about this.
ASP.NET fails to Detect IE10 ...
The quickest solution from this Blog article is to use NuGet to add updated App_Browser files to your project. The Blog includes additional options, and is worth a read.

Visual Studio | ASP.NET Configuration error

I have a problem as I have struggled with for a week.
Now I give up! I really can not figure out how to solve it. Every time I open the ASP.NET Configuration in VS10, then comes the first with this error:
**An error was encountered. Please return to the previous page and try again. **
If I then press:
How do I Use this Tool
so this comes up:
**Tool Has Timed Out
As a security measure, the Web Site Administration Tool times out after a period of inactivity. Changes to machine.config or web.config may also result in the tool needing to be restarted. To continue configuring your web site, restart the tool. **
Some who can answer me on what's happening here?
"Special characters in the path may be the problem, according to the posts." as Posted above by Dave Swersky
THIS worked perfectly for me! I had a special character ("#") in my folder path I removed this and removed spaces for good measure!
I was getting the error "Tool has timed out" among other errors when accessing the WSAT(Web site administration tool) from the ASP.NET configuration menu item.
I saw a post somewhere else that said the problems was solved when the default browser was changed to Internet Explorer. I have been using Firefox and have the exact same problem. When I changed the default browser to IE, the configuration page came up with no problem. But it won't work twice in a row without going in and setting the default browser back to IE each time. When I go back in to Program Access and Defaults, "Use by current browser" is selected. I have to reselect IE, and then it will work one time.
Judging by the Connect site, this error has been reported and is not well understood:
http://connect.microsoft.com/VisualStudio/feedback/details/118567/an-error-was-encountered-please-return-to-the-previous-page-and-try-again
Special characters in the path may be the problem, according to the posts.
This is what worked for me.
I'm using Visual Studio 2010 trying to create the membership role. I was trying to use the ASP.NET Configuration in Visual Studio.
Set the 'Default Browser' to Internet Explore.
To do this:
Right click on one of the .aspx pages you have under "Solution Explorer".
Select "Browse With..."
Select Internet Explore and Click on Set as Default.
Close the box.
Go back and click on "ASP.NET Configuration"
This will automatically open Internet Explorer.
Problem Solved :D
I guess what I was doing wrong was using Firefox as the default browser with Visual Studio. I'm guessing Visual Studio works good together with Internet Explorer since Momma and Daddy made them together (awww how cute)
The issue might be related to an application path that has spaces. After googling I managed to bypass the issue by appending the application path to the url manually ie.
http://localhost:{your_port_here}/asp.netwebadminfiles/default.aspx?**applicationPhysicalPath={path_to_your_application}&applicationUrl=/**
As a firefox user, I closed firefox then executed the "ASP.NET Configuration" option in VS2010. It automatically opens firefox (default browser) and now I am seeing WAT page contents.

SSRS - find, scroll

SSRS has a find button on the toolbar. Hosting an SSRS report control in ASP.NET and when you use the find and it finds something at the bottom of the report, it doesn't scroll down automatically. Wondering if anyone has seen or done anything to make the scroll happen on find in the SSRS report?
Make sure you are running the most updated version of SSRS. I recall in the past some of these controls were broken and fixed in a later release.
Ensure Javascript is enabled on your browser and add the site to your trusted list. If I recall correctly, IE has strict default permissions for intranet sites. If that doesn't work, see if it works in another browser and that will help you determine if it is browser related.
Make sure you have all CSS and javascript resources on your server. My reports contain a reference to: "assets/js/app-ffc8de72-74aa-48f8-bf1d-634ee0627bca-bundle.min.js".
I can confirm this feature is working in SSRS 2016.
