I am creating a download manager, and I need to be able to find out what link was clicked on (so my download manager can begin downloading the file), and also need to be able to stop the browser from launching its default download manager.
Does anyone know how to go about doing this, or know of any links to articles/tutorials/related docs?
As far as I know, the only way is to write a pluggin for IE which is done through Browser Helper Objects and that is unmanaged C++. Have a look at this:

I know By using WebClient class we can download the files directly.
By using this code web.DownloadFile("url", "filename");
But in my scenario I should call this(https://www.nseindia.com/reports/gsm) link and when this link triggered the "Download (.csv)" link should download automatically (you can see this download option in image and highlighted with blue color circle)
Note :
if I click on this download link it starting the downloading in the same link and will not not giving the download link separately. So I should call this download link through the coding only.
So how can we achieve this type of file downloading's.
Give me your best suggestions to achieve this.
A general approach to solving problems like this:
Open the network tab on your browser devtools
download the object you want to fetch with your program, and
look for the object's download.
Inspect that object in the network tab to determine its Url.
Then try that URL in your (C#) program.
If you get the object, fine. If you don't, the web site owner may have built anti-scraping protection for the object. For example, you may need to be logged in to the site to access the object.
When I open the Chrome's Task Manager, I can see something like this?
Now, programatically, is it somehow possible to target the Chrome instance that is being used to run the Flash Plug-In? Maybe using System.Diagnostics.Process class or native API calls?
I was able to do this with native api calls. My solution worked perfectly on my machine. Here is what I did:
First, get Microsoft Process Explorer. Using this tool, I was able to get the flash plugin dll's name that chrome uses which is called pepflashplayer.dll in my case.
Next, a little search on Bing got me this article. It's C code so I converted to C# and after some coding I was able to retrieve the correct Chrome process ID that uses flash plug-in.
I have uploaded my solution to SkyDrive for you to check here. Note that I am not closing any handles in my sample so you'll have to add that for a real project.
There might be better solutions out there but this one should work. Hope it helps.
I have searched extensively and have not found a solution.
Here is what im looking for:
When a user starts a download in a browser, I wish to move it to the download manager and remove the dialog download from browser, is this possible in C#?
It is fundamentally impossible for server-side code to modify the browser's download experience.
I am making a web browser in C Sharp, I want that all the files downloaded by the user on this web browser from any web sites, web browser saves it in one default folder (i.e C:\Users\Abc\Downloads)
Currently when i try to download file from any url it pops up a dialogue box asking for path, and it is annoying thing to have so i just wants to give one default path where it just saves the file automatically without asking user for the path.
Like we have default download path for Mozila firefox and google whenever user download any file from the web browser it saves in one default folder. so how can I achieve this in .net 4.0 Csharp web browser.
I'm afraid you can't with the webbrowser control,
maybe take a look at

first you don't use IE, and you can do more if I'm right

If you're using the WebBrowser control in c# this can be somewhat of a challenge, but have a look at this link which might help you, I've tried it myself with good results.

Good Luck! :)
Edit:
You might want to look into this solution to your issue as well:
Automated filedownload using WebBrowser without url
:)
I need to be able to follow an URL until all redirects are finally over and a file download commences. Think for example of Sourceforge download URLs. I am not talking just about plain HTTP redirects but Javascript too.
I am constrained to pure managed WinForms NET 2.0. I have been using WebClient successfully until this redirect problem came up. I thought I could simply use WebBrowser, navigate to an URL and wait. But I need to do the download entirely without user intervention and additionally monitor the download progress. There appears to be a FileDownload event but it only seems to be raised after a successful download is complete.
Any help is appreciated.
Sorry this is not possible since you ruled out the native download manager APIs (C# wrapper here).
Why you rule out native code? The Webbrowser class itself is not pure managed either. It is built on top of native IE APIs.
