Cancel the close event, window was closed

CodePudding user response:

Write your function? There is a problem,
Private void Window_Closing (object sender, System.Com ponentModel CancelEventArgs e)
{
E.c. with our fabrication: ancel=true;
}

CodePudding user response:

Writing is no problem, can use, but you should confirm whether have big forms set of small form, other places have shut down,

CodePudding user response:

Not rewrite OnClosing, but Windows. Closing +=(o, e)=& gt; {e.c. with our fabrication: ancel=true; };
