RichTextBox color

问题

I wish color of text was e.g green when user inputs it into RichTextBox control. I use sth like:

 private void richTextBox1_TextChanged(object sender, CancelEventArgs e)
{
    RichTextBox richTextBox1 = sender as RichTextBox;
    richTextBox1.SelectionBackColor = Color.AliceBlue;
}

But it cause that first sign is in normal background, and starting from second sign whole eneterd text is blue:

pattern(upper case is colored): eNTERED TEXT

回答1:

Instead of TextChanged try it on OnKeyDown

回答2:

I presume you want to set:

richTextBox1.ForeColor = Color.AliceBlue

somewhere after your InitializeComponent(); or via the Background property in the Designer.
