cefsharp

问题 So here is the scenario, using CefSharp in a WinForms application. We have two pieces of information a page url and a link url within that page. We want to load the page - easily done, and have CefSharp show the area of the page where the link is located. That is cefsharp automatically scrolls to the right location on the page where that link is within the DOM. What is the easiest way of doing that? 回答1: Not sure which version you're using, I was able to solve this using the latest stable

问题 For a project I am working on I need to inject javascript prior to any of the webpage document processing begins. This can easily be achieved via the WebBrowser component, but I am encountering difficulty using CefSharp. Here is a simplification of the problem, a webpage needs an "InjectedObject" to be present to function. Calling the webpage without injection occurring at the very top of the document, or being evaluated/executed before the document is processed would result in: =====html

问题 I have a CefSharp window in my WinForms app and I'd like to access the network tab in dev tools and copy some stuff from there (like loading times, URLs...). Is that possible with CefSharp? Or is there any other browser implementation for C# that will allow me to do this? Thanks! 来源： https://stackoverflow.com/questions/62782579/cefsharp-accessing-chromium-dev-tools-with-code-network-tab

问题 I need to be able to retrieve a Pdf from our web server via a call to Web API and then render the document in the ChromiumWebBrowser for CEFSharp, all within memory and not saving the file locally. Right now I'm at the point where I get back the file in a MemoryStream, but can't seem to get any further. Is this possible? Any examples would be greatly appreciated. Thanks. 回答1: You have two options, implement a Scheme Handler for your own custom scheme , e.g. client:// or implement a Resource

问题 How can I intercept a js onClick on a button in an Html document that is running under WinForms with CefSharp browser controller so that C# code can intercept this event and do some actions already in .NET environment? 回答1: For basic communication you can use CefSharp.PostMessage(message); in Javascript to send a message to .Net which triggers the browser.JavascriptMessageReceived event. // After your ChromiumWebBrowser instance has been instantiated (for WPF directly after

问题 I have been having a murderous time with CEFSharp in WinForms since Visual Studio decided to update it to build 77.1.18 and Nuget messed the whole thing up leaving three versions installed but refusing to uninstall any of them! In order to resolve the issues I had to manually edit various solution and project files, and got it so that I have build 75 installed and mostly working. The system then notified me that DefaultRequestHandler was now obsolete, and that I should use RequestHandler
