Hello Zhou,

Thank you for writing.

I am not sure what exactly is the specific case, but following your sample code I noticed that you are trying to cast a RadControl to MS TextBox instance, which is not supposed to succeed. In order to clear the text from all RadTextBox controls, you must cast to RadTextBox:

private void radButton1_Click(object sender, EventArgs e)
{
    foreach (Control ctrl in this.Controls)
    {
        RadControl rc = ctrl as RadControl;

        if (rc is RadTextBox)
        {
            rc.Text = "";
        }
    }
}

I hope this information helps. Should you have further questions, I would be glad to help.
