C# Window ComboBox highlight Default Text Displayed

Question

Hi, I have a comboBox and it was a number of values. On Form_Activated event I will pick the first item in the comBoBox and assigned it to ComBoBox.Text (default Text displayed). Afte that I need to highlight the default text display with a color so that user can see that the text is selected. Example: dialedNumberComboBox.Focus(); if (dialedNumberComboBox.Items.Count > 0) { dialedNumberComboBox.Text = (dialedNumberComboBox.Items[0]).ToString(); // Here I need to highlight the text in dialedNumberComboBox.Text } Thanks.
