Call me crazy but doesn't Ctrl+A always select all in a textbox. You don't need to write code for it.

But textboxes do it without you needing to write code.

I said this too. there's a wheel out there already but it needs reinventing for some reason.

no sir i am doing my project in windows form and in windows form textbox doesnt do it automatically
jim lahey - 8-Nov-12 9:07am
Yes it does, I just tried it myself.
ryanb31 - 8-Nov-12 9:07am
Then something is broken. They do select all by default.

i am using vs 2010 and in win xp i dont know how you can do this shortcut. It is not available here. Is it was there so why i didint try that?

If you really need to handle the Ctrl+A, you wire key press event of text box to one event handler as shown below in form load.
 
 textBox1.KeyPress += new KeyPressEventHandler(CommonKeyPress);
 textBox2.KeyPress += new KeyPressEventHandler(CommonKeyPress);
 
Then your function below should work great !
 
private void CommonKeyPress(object sender, KeyPressEventArgs e)
{
  if (e.KeyChar == '\x1')
  {
    ((TextBox)sender).SelectAll();
    e.Handled = true;
  }
}

You can simply assign this handler to the KeyPress event of any TextBox you need. You've done the hard work by casting the sender parameter.
 
One question though, do you really need to do this? Ctrl + a is select all just about everywhere..
