keypress event problem

Question

Hi all,

I have two textboxes in design namely txtcode and txtnumber.When im entering some number into txtcode, txtnumber should also have that number.for this I tried a simple logic that

txtnumber.text=txtcode.text

inside keypress event of txtcode. But the issue is that, if i presses any number first that is the first digit of the textbox its not appearing in txtnumber but appearing in txtcode only.After i presses second number then only the first number is appearing in txtnumber.Because of this conflict,there is a single number lagging in txtnumber while compare to txtcode.

how to solve this issue???

Answer 1

The problem is that the KeyPress event fires before the text in the TextBox has been updated, so the key that is being pressed is not yet in txtcode.Text at the time you are copying it.  Use the TextChanged event instead. 

Answer 2

try like this.. .

public void txtcode_keyDownEvent ( object sender , EventArgs e )

{

 if ( e.KeyCode == keys.Enter)

{

txtnumber.Text = txtcode.Text;

}

}

//////////////////////// or /////////////////////////////

public void txtcode_TextChangedEvent ( object sender , EventArgs e )

{

 txtnumber.Text = txtcode.Text;

}

In addition to Blackwood, you can also use the KeyUp of course.
