网上找的PrintListView类,用于打印ListView,网上没有具体的引用方法。我进行了修改,将里面的this,改成了传进来的MYListView对象。打印里,无法弹出PrintDoialog,所以将弹出来的代码注释了,直接打印。
使用方法:
PrintListView plv = new PrintListView();
plv.MYListView = lvCallRecord;
plv.IsPreview = false;
plv.DoPrint();
以上是关于网上找的PrintListView类,用于打印ListView,网上没有具体的引用方法。我进行了修改的主要内容,如果未能解决你的问题,请参考以下文章
