Parameters

chromiumWebBrowser

the ChromiumWebBrowser control

the browser object

Type: CefSharpCefJsDialogType

messageText
Type: SystemString
Message Text
defaultPromptText
Type: SystemString
value will be specified for prompt dialogs only
callback
Type: CefSharpIJsDialogCallback
Callback can be executed inline or in an async fashion
suppressMessage
Type: SystemBoolean
Set suppressMessage to true and return false to suppress the message (suppressing messages is preferable to immediately executing the callback as this is used to detect presumably malicious behavior like spamming alert messages in onbeforeunload). Set suppressMessage to false and return false to use the default implementation (the default implementation will show one modal dialog at a time and suppress any additional dialog requests until the displayed dialog is dismissed).

Return Value

Type: Boolean
Return true if the application will use a custom dialog or if the callback has been executed immediately. Custom dialogs may be either modal or modeless. If a custom dialog is used the application must execute |callback| once the custom dialog is dismissed.
