Dear colleagues

I need instance class ReportPrintEventArgs that active

private void reportViewer3_Print(object sender, ReportPrintEventArgs e)
       {
           reportViewer3.PrinterSettings.PrinterName = e.PrinterSettings.PrinterName;
           reportViewer3.PrinterSettings.FromPage = e.PrinterSettings.FromPage;
           reportViewer3.PrinterSettings.ToPage = e.PrinterSettings.ToPage;
           e.Cancel = false;
           reportViewer3.PrintDialog(reportViewer3.PrinterSettings);
           nn = e;

       }

另一种方法的方法

method to another method

推荐答案

你可以通过它如果你从事件处理程序中调用它，那么你需要做的就是编写一个接受ReportPrintEventArgs作为参数的方法。



但是...它不是尝试处理事件之外的事件args是一个好主意，特别是如果你试图将它们留待以后，这样一个不同的方法可以收集它们并使用它们 - 到那时它们可能很好并且真正过时了！ br />


你想用不同的方法想要EventArgs做什么？

You can pass it through to another method if you call it from the event handler - all you have to do is write a method that accepts ReportPrintEventArgs as a parameter.

But...it's not a good idea to try and handle the event args outside the event, particularly if you are trying to "leave them for later" so a different method can collect them and use them - they could be well and truly out of date by then!

What are you trying to do that you want the EventArgs in a different method anyway?
