    Hi Saikiran,

    Thank you for writing.

    You can change the border color of the text box by setting the ForeColor property of the BorderPrimitive:
    public Form1()
        radTextBox1.Validating += new CancelEventHandler(radTextBox1_Validating);
        radTextBox1.Validated += new EventHandler(radTextBox1_Validated);
    void radTextBox1_Validated(object sender, EventArgs e)
        radTextBox1.TextBoxElement.Border.ForeColor = Color.FromArgb(156, 189, 232);  
    void radTextBox1_Validating(object sender, CancelEventArgs e)
        radTextBox1.TextBoxElement.Border.ForeColor = Color.Red;
        if (RadMessageBox.Show("Validated", "",  MessageBoxButtons.YesNo) == System.Windows.Forms.DialogResult.No)
            e.Cancel = true;

    I hope that you find this information helpful. Should you have any other questions, do not hesitate to contact us.
    All the best,
