Access contents \ HTML of an Iframe using WebBrowser control in WinForms
Hi,
I need to read the innerText \ InnerHTML of an iframe.
I have located the frame that I need using
but, when I go to read the innerText \ innerHtml it returns nothing.
looking at the watch window there it is reading nothing, and other elements in other frames read "" or nothing
Any help on how I should be able to get this information would be very much appreciated.
thanks
Simon

Would it be possible for you to post a sample source HTML which against which you are executing this code and highlight the inner text that you expect as output?

Hi Karrtik,
I will pass what information I can as much as possible in a few minutes for you, as some of this is sensitive data I will have to remove\replace some of the names and variables.
however, using
gives me html output for the frame, but it does not match what I would get if I did a right click and view source. However, if I put the scraped html into a html file and show it it does show the right data.
But there is information in the original source file (from right click view source) that I need, that isn't in the source code that I am pulling from the code.

Actually, having compared the data again, its missing the javascipt variables at the top of the page in the <head> tag which is the only bit that I need.
any suggestions?

this wasn't an easy solution as many posts I have looked at on the net found a lot of people saying that it couldn't be done...
this took a lot of inspecting each of the elements and properties of an object.... (painstakingly)
