chromiumWebBrowser1.ShowDevToolsDocked(panel2);
在调用DevTools显示到pannel2时，当窗体大小改变，而控件不会随着窗体大小改变。
解决办法如下：
在浏览器控件中加入生命周期处理程序LifeSpanHandler ，就可以随着窗体大小显示了。

chromiumWebBrowser1.LifeSpanHandler = LifeSpanHandler.Create().OnBeforePopupCreated((chromiumWebBrowser, b, frame, targetUrl, targetFrameName, targetDisposition, userGesture, browserSettings) => { //Can cancel opening popup based on Url if required. //if (targetUrl?.StartsWith("/cancelme.html") == true) //{ // return PopupCreation.Cancel; //} return PopupCreation.Continue; }).Build(); |

string url = "www.baidu.com"; chromiumWebBrowser1.Load(url); chromiumWebBrowser1.KeyboardHandler = new CEFKeyBoardHander(); chromiumWebBrowser1.LifeSpanHandler = LifeSpanHandler.Create().OnBeforePopupCreated((chromiumWebBrowser, b, frame, targetUrl, targetFrameName, targetDisposition, userGesture, browserSettings) => { //Can cancel opening popup based on Url if required. //if (targetUrl?.StartsWith("/cancelme.html") == true) //{ // return PopupCreation.Cancel; //} return PopupCreation.Continue; }).Build(); |
