TdxAlertWindowManager.OnHyperlinkClick Event

Allows you to handle a click on a hyperlink displayed in an alert window.

Declaration

property OnHyperlinkClick: TdxAlertWindowManagerHyperlinkClickEvent read; write;

Remarks

The OnHyperlinkClick event occurs every time a user activates a hyperlink in an alert window. You can handle this event to implement a custom response to hyperlink activation or prevent users from activating certain hyperlinks.

Code Example: Prevent Navigation to External Web Resources

The following code example prevents hyperlink activation if the clicked hyperlink in an alert window refers to an external web resource:

Delphi

procedure TMyForm.dxAlertWindowManager1HyperlinkClick(
  Sender: TObject; const AURI: string; var AHandled: Boolean);
begin
  if ContainsText(AURI, 'http') then  // If the target URI includes the HTTP or HTTPS protocol
    AHandled := True; // Disables the hyperlink activation routine
end;

C++

void __fastcall TMyForm::dxAlertWindowManager1HyperlinkClick(
  TObject *Sender, const UnicodeString &AURI,
  bool &AHandled)
{
  if(ContainsText(AUri, "http"))  // If the target URI includes the HTTP or HTTPS protocol
    AHandled = true; // Disables the hyperlink activation routine
}
