Hello RomRor,

Thank you for your post. I have been looking through it and I attached a sample project which basically has a XamDataGrid and a XamSlider, which controls the FontSize and a ComboBox, which controls the TextAlignment of the XamDataGrid. Please note, we are making efforts to ensure all posts are addressed by an Infragistics expert. We believe that the other community members could benefit from this thread as well.

If you have any further questions on this matter do not hesitate to ask.
