So I’ve been having this wierd problem with event execution order where half way through handling one event another event handler is fired. If you know why please enlighten me!
Here’s a copy of my newsgroup post which you can find here.
I am seeing some unexpected behaviour in a single threaded winforms app
and was hoping someone could explain what is going on.
I have two events attached to a chart control on my form, and during
execution one event seems to preempt the execution of the other.
My code looks similar to the following:
private void MyChart_Click(object sender, System.EventArgs e)
…do some logic tests
// This event is attached to the context menu for the chart control.
private void DrillDownMenuItem_Click(object sender, System.EventArgs e)
private DataSet GetSomeData()
…Call web service
What happens is that when I right click and select drill down from the
chart controls context menu the MyChart_Click event fires and does the
logic tests. Execution then steps into the GetSomeData method, but when
the web service is called execution jumps to the
DrillDownMenuItem_Click event. This runs to completion then execution
returns to the GetSomeData method which finishes and finally returns to
the MyChart_Click event handler.
Can someone explain why this is so?
[EDIT] so I figured it out by myself. I turns out it is a bug in the dundas chart control >:-(
