How to focus a BarEditItem of a merged RibbonControl after showing an MDI child
Answers approved by DevExpress Support
Hello,
After ribbons are merged, an additional link to your original BarEditItem is created and put to the master RibbonControl So, you need to focus the second item's link.
In addition, it is better to wait until the merging algorithm is completely executed. As a result, re-write your line in the following manner:
C#BeginInvoke(new Action(() => {
((BarEditItemLink)form.BarItem.Links[1]).Focus();
}));
I hope you find this information useful.
