    I need to change the background color for input type controls (Textbox, etc...) when their property for ReadOnly is equal to True. Currently, it stays white and the font is bold. I'm new to VSB. I watched the videos and looked through the documentation, but I didn't see how to set the background color based on a control's ReadOnly property state. Is this possible? and if so, how is this done in VSB?

     

    Thanks!

    Hello Bob,

    You can set the styles only for the predefined states and there is no state for the read-only mode. In this case, you can create a custom control that inherits RadTextBox and handle this there:
    class MyTextBox : RadTextBox
    {
       public MyTextBox()
        {
            this.ReadOnlyChanged += MyTextBox_ReadOnlyChanged;
        }
     
        private void MyTextBox_ReadOnlyChanged(object sender, EventArgs e)
        {
            if (this.ReadOnly)
            {
                this.BackColor = Color.Green;
            }
            else
            {
                this.BackColor = Color.White;
            }
        }
    }

    I hope this will be useful. Let me know if you have additional questions.
