Hi,

is there a way to connect to a event when the ViewRange or PageRange is changed?

I have see the Scrollbar has such a event, but its only fired if someone scroll, but this is not what i want. The way with the OnAfterpaint callback is also not usable for me.

Hi Andre,

If you're using the NDataZoomTool to modify the range you can hook to the EndDrag event there:

dataZoomTool.EndDrag += new EventHandler(dataZoomTool_EndDrag);
....

void dataZoomTool_EndDrag(object sender, EventArgs e)
{
// do something on end drag
}

Hope this helps - let us know if you meet any problems.

Yes, thats it. Thank you. I use this events as well for moving constant lines and so on.

Sometimes i can not see the forest for the trees. Too much lines of code in my head.
