To reproduce: this.radTextBox1.Text = "sample"; this.radTextBox1.TextBoxElement.BackColor = Color.Red; this.radTextBox1.TextBoxElement.UseDefaultDisabledPaint = false; this.radTextBox1.TextBoxElement.Enabled = false; In previous version (e.g. Q1 2014 SP1) the TextBoxElement is not rendered red.
No, it is not. RadTextBox internally hosts the standard TextBox control hence it cannot change its forecolor when disabled. You can try RadTextBoxControl which supports such functionality (http://docs.telerik.com/devtools/winforms/editors/textboxcontrol/textboxcontrol).
Is it suppose to work for the ForeColor as well?
Hi Eric, yes, this was introduced back in Q3 2014.
has this feature been implemented since 2014?
