User cannot insert decimal data when editing an item
Reproducible only in .Net 4.5.

Another possible solution would be to set the FrameworkCompatibilityPreferences.KeepTextBoxDisplaySynchronizedWithTextProperty to false.

This behaviour is reproducible only in .Net 4.5. It can be observed with a TextBox outside of RadDataForm if its Binding.UpdateSourceTrigger property is set to PropertyChanged. As it turns out, this behaviour is the expected one since Microsoft had introduced it as a fix for an issue in .Net 4.0. You can check the following article:
for a reference. As Microsoft had stated: If you're targeting 4.5+ and you really want UpdateSourceTrigger=PropertyChanged, consider also setting Delay=300. This property (new in 4.5) causes the binding to wait 300ms before committing the edit, giving the user time to type a digit after the decimal point. This also delays the validation feedback until the user has been idle for 300ms - you may or may not like this. [The value 300 is just what I've found to be comfortable; you can adjust it to your own taste.]
