C# Textbox Auto Scroll To End ScrollToCaret Scrolling Textbox

Many of my sample C# codes,
I use textbox to write the results.

When textbox is multiline property set to true, and when I insert text into it,
I want it to auto scroll to the last line.

Here is a simple way to auto scrolling textbox.
 textbox1.SelectionStart = textbox1.Text.Length;
textbox1.ScrollToCaret();
textbox1.Refresh();
Textbox SelectionStart will force the textbox control to select the last part of the text,
and ScrollToCaret() function will auto scroll textbox to the end.

TextBox1.AppendText() works fater, not blinking and scroll text.

TextBox.AppendText() works awesome, and requires just 1 line of code! Thanks a lot!

at least for me this line was unnecessary:

textbox1.SelectionStart = textbox1.Text.Length;

Somebody suggested TextBox1.AppendText()

but I'm not sure it is designed for this purpose

have to test it and check if there are some drawbacks

tbPositionCursor.Select(tbPositionCursor.Text.Length, 0);

Easy as that...

You can also use the built-in function for this..

textbox1.ScrollToEnd();

This is working but to avoid scroll bar flicker just use:

textBox.AppendText(myTextToAdd);

textBox.AppendText(myTextToAdd);
Will give error "Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: chunkLength" when myTextToAdd has large text... i.e. 2000 lines

There is no AppendText, nor ScrollToEnd on Compact Framework, Select doesn't seem to work, and authors proposition causes flickering of scrollbar :P

Thanks a lot! This really helped me. It's strange that I wasn't able to find anything like this offered in Visual Studio 2008. Would be nice to have it in the properties menu of the text box.

My textBox is named "inputText":

inputText.AppendText(charTxt);
inputText.Select(inputText.Text.Length, 0);
inputText.Focus();
