How do manually invoke a BarItem.ItemClick event handler

use the following code to emulate a mouse click on a bar item:

[C#]
DevExpress.XtraBars.ViewInfo.BarSelectionInfo info;
info = (DevExpress.XtraBars.ViewInfo.BarSelectionInfo)barManager1.InternalGetService(typeof(DevExpress.XtraBars.ViewInfo.BarSelectionInfo));
// item must have a visible item link!
info.ClickLink(barButtonItem1.Links[0]);

However, it may be easier to call an event handler directly in a particular situation:

[C#]

...

barButtonItem1_ItemClick(barButtonItem1, new DevExpress.XtraBars.ItemClickEventArgs(barButtonItem1, barButtonItem1.Links[0]));
...

private void barButtonItem1_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e) {
    // your code is here
}
