Hi,

Try the following code on RichTextBox controls TextChanged event

private void rt_TextChanged(object sender, EventArgs e)
{


Font tempFont = ((RichTextBox)(sender)).Font;



int textLength = ((RichTextBox)(sender)).Text.Length;

int textLines = ((RichTextBox)(sender)).GetLineFromCharIndex(textL ength) +1;

int Margin = ((RichTextBox)(sender)).Bounds.Height -((RichTextBox)(sender)).ClientSize.Height;

((RichTextBox)(sender)).Height = (TextRenderer.MeasureText(" ", tempFont).Height * textLines) + Margin +2;
