[WinForm] How to disable error prompts when webBrowser displays html content in C# Winform

[Copy link]
Posted on 7/8/2017 11:33:19 PM | | |

In WinForm, there is a control that can display HTML content, which is the webbrowser, and set its DocumenText property to HTML content.

When using WebBrowser for UI, we sometimes don't want the link in it to be clicked by the user, let alone the annoying script error prompt box popping up, and we don't want the user to be able to click the right-click IE menu.
Disable error script hint: Set the WebBrowser control's scrip{filter}tErrorsSuppressed to true
Disable Right-Click Menu: Set WebBrowser's IsWebBrowserContextMenuEnabled to false
Disable shortcuts: Set WebBrowser's WebBrowserShortcutsEnabled to false
Disable hyperlinks : There are two types of hyperlinks, one is direct to the current window, and the other is to open in a new window  
Of course the window turns directly: Set the WebBrowser's AllowNavigation to false
Disabling new window openings requires handling the WebBrowser's NewWindow event


After completing the above work, it is basically complete, and there is one last point to pay attention to, which is Drag-And-Drop. Remember to set the WebBrowser's AllowWebBrowserDrop to false
