Hello Frank,

Thank you for writing.

In the TextViewCellFormatting event it is necessary to set the DrawFill property to true in order to obtain the correct coloring. You can refer to our GanttView >> TextView item formatting help article which is quite useful on this topic.

Note that Font creation is a heavy operation and it is not recommended to be performed in the formatting event which is fired a lot of times. I would recommend you to create the font just once and use the font variable in the TextViewCellFormatting event.

I hope this information helps. Should you have further questions, I would be glad to help.

Regards,
