When a property based on an enum is changed, the change is not applied unless you hit ENTER or click elsewhere on the property grid. This issue can be demonstrated by the PropertyGrid->Setttings demo. Change the “AccessibleName” property and then click on the “UI Settings” groupbox so the property grid loses focus and you can see the property get applied. Do the same thing with “AccessibleRole” and the change is not applied until you click back on the property grid.

Hello Sean,
Thank you for writing.
I was able to reproduce the issue you have described and have logged it in our Public Issue Tracking System - PITS. You can track its progress subscribe for status changes and add your vote comment to it on the following link - PITS Issue. Until the issue is resolved you can workaround it by subscribing to the EditorInitialized event of RadPropertyGrid and in the event handler subscribe to the editor element's RadPropertyChanged. In that event handler you can track whether the property being changed is ContainsFocusProperty and if it is call the property grid EndEdit method. Here is how your code would look like:
I have also updated your Telerik Points for bringing this issue to our attention.
I hope this will be useful. Should you have further questions, I would be glad to help.
All the best,

Having the same problem for a VB project, unfortunately the #C code is rather hairy to be translated to VB,
any friendly suggestions on how to implement this in VB?
Thanks,
private void element_RadPropertyChanged(object sender, RadPropertyChangedEventArgs e)
{
if (e.Property == RadElement.ContainsFocusProperty && !(bool)e.NewValue)
{
this.radPropertyGrid1.EndEdit();
}
}

Hi, thanks for feedback
Although the proposed solution is a work around to the problem, there is a remaining troublesome issue that I want to check if it also happens to others.
When the user clicks on the dropdown list box to select a new enum option, instead of the currently selected value to be chosen and highlighted, the focus moves to first first available option in the list.
This is not the normal drop down list behavior and it could be confusing to the end user, since this value is being displayed until you click somewhere else and then the properly selected value is displayed.
Regards,
George

Hello George,
Thank you for writing.
I have tested the described behavior both with and without the workaround provided, however, the selected item was correctly selected in the drop down as well. If you continue experiencing this issue, please open a new support ticket with a sample demonstrating the issue and we will be happy to help you with it.

Hello,
I have the same problem in my application. The solution has fixed the problem, but I tried to apply that for a BaseSpinEditorElement and the problem is when the user click on the narrow down or up, it loses the focus and the value is not changed. What should I do?
p.s.: the problem with the dropDownList occurs as well with the BaseSpin. The change is not applied unless you hit ENTER or click elsewhere on the property grid.

Hi Filipe,
I can confirm that this problem occurs with the spin editor as well and I have logged it accordingly. Here is a link to the item: http://www.telerik.com/support/pits.aspx#/public/winforms/15799.
You can use the same workaround for this editor as well.
I have updated your Telerik Points for this report.
