Hello jiang,

Can you please elaborate on your scenario? I tried to reproduce the issue by adding the RadRichTextBoxRibbonUI in the Controltemplate of the DataForm and it works as expected. Can you please modify the project to reproduce the issue so that we can further investigate it? Thank you in advance.

All the best,

Hi jiang,

Thank you for your report. It seems that it is related with the RadRibbonBar control and I added it as a bug in our PITS under the name RibbonBar: DialogLauncherButtonStyle dependency property exception is thrown and you will be able to track its progress from tomorrow the latest.

I also updated your Telerik points accordingly.
