Input simulation

This example shows how to simulate keyboard and mouse input in a web page from C# code. It contains two WPF applications that do the same thing, one with DotNetBrowser and one with CefSharp, so that you can compare the code. Each application loads a bucket list page, types a task into the text field, and clicks the Add button.

The tutorial is available on the DotNetBrowser blog.

Prerequisites

• .NET 8 SDK
• A DotNetBrowser license key
• Visual C++ Redistributable 2022 (x64), required by CefSharp

Project structure

• shared/bucket-list.html is the page both applications load. Its Add button is enabled only by input events.
• DotNetBrowserApp/MainWindow.xaml.cs raises keyboard events on IBrowser.Keyboard and clicks the button with IMouse.SimulateClick().
• CefSharpApp/MainWindow.xaml.cs sends key and mouse events through IBrowserHost and gets the button position with JavaScript.

Set the license key

Put your license key into the dotnetbrowser.license file in the root directory of this repository. The build copies it to the output directories of both applications.

Run the example

From this directory:

dotnet run --project DotNetBrowserApp
dotnet run --project CefSharpApp

Or open InputSimulation.sln in your IDE and run either project.

In the window, click Type task, then Click Add. The task appears in the list.
