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()
{
    InitializeComponent();
    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,
