[c#] Setting cursor at the end of any text of a textbox

I have a text box with a displayed string already in it. To bring the cursor to the textbox I am already doing

txtbox.Focus();

But how do I get the cursor at the end of the string in the textbox ?

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

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);

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.
