Answer 1

For Windows Forms you can control cursor position (and selection) with txtbox.SelectionStart and txtbox.SelectionLength properties. If you want to set caret to end try this:

txtbox.SelectionStart = txtbox.Text.Length;
txtbox.SelectionLength = 0;

For WPF see this question.

Which post says NOT to use SelectionStart. – Bake

I don't think we need -1, if we won't to put the input cursor at the end of textbox. – Urinalysis

Math.max(0, txtbox.Text.Length -1); // Math.max is the logic if length is 0 – Columbarium

@YuchenZhong is right, -1 puts the insertion point before the last character (her|e) instead of after it (here|). Also, text boxes have a .TextLength property so all you need is txtBox.SelectionStart = txtbox.TextLength. – Indispose

@PanagiotisKanavos the post he links is for WPF, whereas the answer given is for Windows Forms. – Indispose

@Indispose exactly. The question is tagged WPF but the answer is about Windows Forms. WPF allows caret positioning directly – Bake

@PanagiotisKanavos Oops, I missed that the question was WPF... – Indispose

This worked for me, thanks. – Lager

Worked for me. Good for if contents of the TextBox (e.g. path to a file) is too long for the displayed box and you actually need to see the filename – Eunaeunice

Answer 2

There are multiple options:

txtBox.Focus();
txtBox.SelectionStart = txtBox.Text.Length;

OR

txtBox.Focus();
txtBox.CaretIndex = txtBox.Text.Length;

OR

txtBox.Focus();
txtBox.Select(txtBox.Text.Length, 0);

That sets the selection, not the cursor position – Bake

Answer 3

You can set the caret position using TextBox.CaretIndex. If the only thing you need is to set the cursor at the end, you can simply pass the string's length, eg:

txtBox.CaretIndex=txtBox.Text.Length;

You need to set the caret index at the length, not length-1, because this would put the caret before the last character.

Try like below... it will help you...

Some time in Window Form Focus() doesn't work correctly. So better you can use Select() to focus the textbox.

txtbox.Select(); // to Set Focus
txtbox.Select(txtbox.Text.Length, 0); //to set cursor at the end of textbox

The OP asks about the cursor position, not the selection – Bake

@PanagiotisKanavos: Can you read my post correctly before comment... – Penner

From the docs TextBox.Select Method: Selects a range of text in the text box. While you can emulate positioning by manipulating the selection, it's better to just place the cursor where you want it – Bake
