How to keep a vertical scrollbar on a multiline textbox always scrolled down?<br />
<br />
My multiline textbox is being used as a chat text box. &nbsp;When the text inside gets too big I have to trim the top but keep the chat contents on the bottom.<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; If txtMessageHistory.Text.Len<wbr />gth &gt;&nbsp;2048 Then<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'take the last 2048 characters and set that<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; txtMessageHistory.Text = txtMessageHistory.Text.Sub<wbr />string(txt<wbr />MessageHis<wbr />tory.Text.<wbr />Length - 2048, 2048)<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'scroll the scrollbar all the way down<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ?? HELP <br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; End If<br />
<br />
The scrollbar gets set all the way up instead of staying scrolled down.<br />
<br />
Any suggestions?
