Hi,
I want to derive of of TextBox, and add on an auto-scroll-to-bottom
boolean property. I can use a regular textbox (rich or otherwise) and
get the effect by:
mytextbox.appen d("my text");
mytextbox.focus ();
mytextbox.scrol ltocaret();
What sorts of things do I need to look into in order to get a property
in a derived class that has this effect?
Thanks for any direction,

Inherit from textbox, add your property and override OnTextChanged and
do your processing in there.

Additionally, it should be stated that calling the focus method is not
advisable. If I was on another control and the focus was suddenly taken
from me, I'd be pissed.

Then I have no idea how to get the textbox to scroll. According to
msdn, the textbox must have focus in order for scrolltocaret to work.
In particular, there simply IS NO CARET unless the textbox has focus.
I'm open to any workaround ideas. (This issue is really why I asked
the question in the first place.)

Yeah. I've run into that before. One more example of why the built-in
controls in Windows Forms are half-baked.
Try using a COM-based textbox. Yeah it's old-school but it's better than
stealing focus...

Is there any way to "remember" what object had focus when the textbox
stole it,
and return focus to that object when the and return focus to it when
the textbox
is done scrolling/updating? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I've successfully implemented AutoScroll capability with one panel and it
works great. But with another panel, when AutoScroll is turned on, an
annoying & unnecessary horizational scrollbar appears.
I'd like to disable it but don't know how. I understand there to be an
"HScroll" property but it's protected and I don't know how to get at it.
Any ideas?

I’m working on a GroupBox and need to set the AutoScroll property to true.
My problem is I have no AutoScroll property listed in the property box.
And even if I go in to the Designer.cs file I can’t find the AutoScroll

Do I need to set something up for this property?
Any help would be appreciated.
