当我移动（调整大小）窗体或组件时，我需要暂停刷新 [英] I Need To Suspend Refreshing When I Move (Resize) Form Or Component

问题描述

当我调整其他控件的大小时，我有问题，我有一个N点添加到我的图表的系列，然后我画一条线

 graph.DrawLine（ new  Pen（Color.Yellow， 1 ），point3，point4）; 

当我调整其他控件的大小时o de形成这条线消失，然后当我在图表中再次出现时。我需要避免消失。



解决方案：我用boolean var调用post paint并重新绘制线条。

解决方案

显然，你做错了。您必须通过在重写的 OnPaint 方法或 Paint 处理程序中进行所有渲染来永久支持绘图/重绘。有关详细信息，请参阅我过去的答案：

when i resize other control o de form this line disapear, then when i zom in the chart appear again. I need to avoid disapear.

SOLUTION: I call post paint with boolean var and repaint the lines.

解决方案

Apparently, you are doing it wrong. You have to support drawing/redrawing permanently, by doing all rendering in your overridden OnPaint method or Paint handler. For further detail, please see my past answers:
