private void button1_Click(object sender, EventArgs e)
{
richTextBox1.AppendText("\r\n");
richTextBox1.Focus();
string s = "Enter ";
richTextBox1.AppendText(s + "\r\n");
richTextBox1.SelectionStart = richTextBox1.Text.Length - (s.Length +1);
richTextBox1.SelectionLength = s.Length +1;
richTextBox1.SelectionFont = new Font("Arial", 12, FontStyle.Bold);
richTextBox1.DeselectAll();
richTextBox1.SelectionStart = richTextBox1.Text.Length;
richTextBox1.SelectionLength = richTextBox1.Text.Length;
richTextBox1.SelectionFont = new Font("Arial", 12, FontStyle.Regular);
richTextBox1.DeselectAll();
}
每次用户单击按钮时,我都希望新的“Enter”位于 RichTextBox 的顶部而不是底部。我该怎么做?
