Auto-Scroll A Textbox?
Jan 10, 2010
Heres my problem, My app outputs info into a textbox as a log and appends the new lines to the end of the textbox, is there a way i can scroll the textbox so it displays the end of the text? I had considered writing the line at the top and appending the rest of the data to it but the line is hard to do this way (it uses info from 2 seperate subs and would need a global or a new textbox) and ideally i would like the info at the end in chronological order. the textbox is refreshed at the end of each entry.

I have this code which places text into a textbox control. [Code] How can I make that textbox autoscroll to the end of the textbox contents? I've read countless times that if I use TextBox1.AppendText instead of TextBox1.Text += the textbox will automatically scroll. [Code]

I am loading several command buttons into it (one in each grid box). I have the panel set to autoscroll. When TableLayoutPanel is set to AddColumns, all works well. However, I dont want horizontal scroll, I want vertical. When I set TableLayoutPanel to AddRows, a vertical scrollbar will not appear.

I have a textbox that shows events on a program, which I add. I use the 'scroll bar' option on the textbox to show the vertical scroll bar, but how do I make it stay at the bottom most possible? I am using this code while I am trying to learn how to do what I want the scroll bar to:[code]But how do I get it so the scroll bar will stay at the bottom-most it can? I'd like the newest, most recent events to appear at the bottom of the textbox, and to have the user not have to scroll down every time something new is added.

Well un-like the textbox when AppendText() is used, the box doesn't auto-scroll down to the end, now I already know about caret position scrolling & all that but if I use it it seems to scroll slightly past the endline about enough to show yet another line if there were one.Now I was going to use code from a post I had inquired about similar but it's not working here in vista(SendMessage function) isn't functioning at all, it says the endpoint wasn't found, I guess meaning the function in the .dll wasn't found to be used.url...It was originally for a textbox to retain position if your not scrolled down to the bottom, which I want to keep such functionality in a RichTextBox but make it scroll to the bottom otherwise(hopefully not the slightly too far problem I have with caret position now...)

I'm having a problem where I have elements such as Listboxes and Rich Text boxes that I want to set to size automatically in xaml according to the size of the window, but I only want it to resize to the size of the window and then put scrollbars if the content is any bigger than that.
Unfortunately, the only way I can get scroll bars to work is if I set a specific height of the listbox/rich text box (which does not work because I want it to automatically resize to the height of the grid that it is contained within, which is generally the height of the window (auto).

A panel with enabled scrollbars has many buttons. If I push the tabulation key, focus navigates between buttons.When a partially visible button has focus, the panel scrolls itself in order to completely show the button.

I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.
Friend WithEvents Panel1 As System.Windows.Forms.Panel
Friend WithEvents btnAdd As System.Windows.Forms.Button
Dim ButtonCount As Integer

I have a texbox that I'm using for a P2P IM program. The box stores all messages but I cannot get it to automatically scroll down to the most recent IM when the box is full and scrollbars are necessary. eg. When a user gets enough messages that they must start using the scrollbars, when a new message comes, the scrollbars reset to the top instead of the bottom where the new message is. Here's the code for adding the message into the box:

I have a program that adds text to a textbox. The textbox is multi-line and has a vertical scroll bar. I want to have my textbox to scroll down automatically when new text is added, however, I do not want the other controls on the form to loose focus.I have tried the following code with no success:
Private Sub txtlog_TextChanged()
txtLog.SelectionStart = Len(txtLog.Text)
End Sub
The code above simply produced no results, it didn't move the scroll bar at all.

1.I want the text to scroll down in the textbox.
Well, if I use AppendText() it does something like this, but if you scroll up, then each time you receive a message you will be scrolled all the way down.
Is there a way to make it scroll all the way down if I am scrolled at the bottom? Meaning, it would check the textbox where its scrolled at, then it would if scrolled to the bottom, and the text and scroll down, otherwise, it would just add the text.
2.Is there a way to make the mouse scroller scroll the textbox? currently it onlt does so when the textbox is the active control on the form, but can I make it always scroll it when the mouse is placed over the control, like it seems to do in MSN when you have a chat open for someone and you are typing a message, you can scroll at the same time without moving focus to the top part where the text is displayed.

I'm currently using a textbox to scroll some info. The problem is it scrolls one line at a time. This creates not a smooth scrolling action ( jumps one line at a time ). I would like a scrolling action like you see in movie credits scrolling smoothly vertically. I don't know if this is even possible with a textbox.

I have a textbox which is inside the second tab of a tab container. When I load the form, I load a file into that textbox. Is there any way to send the scrollbar at the bottom of the text box. I want to show only end part of the file.I have tried this, but it does not work (maybe because is inside a tab container?):
Textbox1.SelectionStart = Textbox1.TextLength
Textbox1.ScrollToCaret()
