如何在Windows Forms WebBrowser控件中拦截刷新？

Question

I'm using the Windows Forms WebBrowser control to display a generated report by setting DocumentText . 我正在使用Windows Forms WebBrowser控件通过设置DocumentText显示生成的报告。 Is there a way I can either prevent the user selecting "refresh" in the right-click menu, or intercept the refresh so that I can regenerate my report? 有什么方法可以阻止用户在右键单击菜单中选择“刷新”，或者拦截刷新以重新生成报告？ At the moment the refresh method reloads "about:blank", discarding my report. 目前，刷新方法重新加载“ about：blank”，从而放弃了我的报告。

        Browser.AllowNavigation = true;
        Browser.DocumentText = "<head></head><body><h1>Test</h1></body>";

So far it seems that refresh does not cause a Navigating event, and I don't get a DocumentCompleted event, even though the control does replace the HTML content. 到目前为止，即使控件确实替换了HTML内容，刷新似乎也不会导致Navigating事件，并且我也没有得到DocumentCompleted事件。 I've tried both settings of AllowNavigation , with no visible difference. 我尝试了AllowNavigation两个设置，没有明显的区别。

You can do it using the OnKeyPress event: 您可以使用OnKeyPress事件来做到这一点：

private void KeyPressed(object sender, KeyPressEventArgs e)
{
       if(e == Keys.F5)
                //do sth;
}

In conjunction with what Simon Mourier said: you could disable the context menu . 结合Simon Mourier所说：您可以禁用上下文菜单。
