What did happen? "It didn't work" is not very helpful!

the curosr didnt return to the start of textbox

Did it go anywhere? Did it disappear? Remember we can't see your screen, so we can only work with what you tell us!

Mohammed Ahmed Gouda 20-Apr-11 5:42am

the cursor remains after the string

Post the relevant code fragment - just the bit which loads the textbox from teh file, and sets the position.

Solution 3

try this:

C#

textBox1.SelectionStart = 0;
textBox1.ScrollToCaret();
this.ActiveControl = textBox1;

it didnt work also may be i wrote the code in wrong place

I edited my solution. Probably you couldn't see the cursor because textBox was not active

My 5, but I must note the last line is redundant, only to convince OP :-)

From your code in comment, I would say, don't change the text in TextChanged event, or remove handler before changing.

C#

textBox1.TextChanged -= textBox1_TextChanged;
textBox1.Text=textBox1.Text.Remove(0, 7);
textBox1.TextChanged += textBox1_TextChanged;

What happens? Share the code.

You shouldn't change the text in textchanged event. Still if you wish, you should unbind event, and then change, then finally bind it.
