It's simpler if you just run the attached sample, and do the following:
1) Clear the 'Name' property value
2) Change the 'Quantity' property value to something other than 10
3) Now, try to click around within the PropertyGrid and see what happens. Also notice that your changes to the 'Quantity' field were not applied.
Based on my root-cause analysis, the problem lies in the AllowExpanding = 'Force' flag. If i set it to 'ForceIfNoTypeConverter' everything seems to behave normally.
