Richard, setting the color of the TextBoxElement will indeed do the job. However, if Jay wants to place this code line in the constructor of the Form which contains the textbox, the better solution is to actually set the BackColor of the TextBoxItem:
.radTextBox1.TextBoxElement.TextBoxItem.BackColor = SystemColors.Control;
Jay, in addition to the code line given above, it will be nice to set the BackColor of the Fill as well. This will allow you to achieve a consistent look:
.radTextBox1.TextBoxElement.Fill.BackColor = SystemColors.Control;
I hope this helps.
