I am sorry that the suggested event is not working for you. However, I am glad that you have found a possible solution to achieve your custom requirements. Yes, it is possible to change the font style to italic of the first item in the RadDropDownList.Items collection. This can be achieved via the Font property as shown below:
Font myFont = new Font("Segoe UI", 14, FontStyle.Italic);
this.radDropDownList1.Items.Font = myFont;
I hope this helps. Should you have any other questions, I will be glad to help.
