c# - Why on Chart control the MouseWheel event never called ? And also the AxisViewChanged never called? -
i have on form1 designer windows forms chart control. in form1 constructor added:
chart1.chartareas[0].axisx.scaleview.zoomable = true; chart1.mousewheel += chart1_mousewheel;
then have mousewheel event:
void chart1_mousewheel(object sender, mouseeventargs e) { messagebox.show("hi"); }
and in designer added event axisviewchanged:
private void chart1_axisviewchanged(object sender, vieweventargs e) { painttocalaculate = true; chart1.invalidate(); }
but using breakpoint in mousewheel event or on axisviewchanged event it's never , stop there.
