I have an embed device which is returning back info in HTML files, Now I trying to make ASP.NET webform application, so end users can see these logs. What is proper way to open HTML file at local server and display inside webform.
If they are complete HTML files (including <html> and <body> tags) then it's probably best to show them in a Frame. Are they in a location you can create an URL for?
For html fragments you'll have to load them in code-behind and show them in for example a Literal control.
