When handling Control.OnKeyPress
event, there is a KeyPressEventArgs
that contains a KeyChar
.
For usability reasons I need exactly the same KeyChar
but when handling OnKeyDown
event.
The KeyEventArgs
does not contains any char related data. I mean, if press the A
key with or without Shift
its not affecting the KeyCode
, KeyData
or KeyValue
. The same when using another language, i still getting capital english values.
How to get a KeyPressEventArgs.KeyChar
inside KeyDown
event?
Thanks.
Convert it. Here is simple function for converting 'A' to 'a'. It converts only capital chars from [A-Z] set. The value 32 is diff between 'A' and 'a'.. Sure you can extend it to your requirements, or ask for feature here.
char getChar( KeyEventArgs e )
{
int keyValue = e.KeyValue;
if ( !e.Shift && keyValue >= (int) Keys.A && keyValue <= (int) Keys.Z )
return (char)(keyValue + 32);
return (char) keyValue;
}
if you need it to works with your current culture you should override ProcessKeyMessage Control method:
protected override bool ProcessKeyMessage( ref Message m )
{
if ( ( m.Msg == 0x102 ) || ( m.Msg == 0x106 ) ) // this is special - don't remove
{
char c = (char) m.WParam; // here is your char for OnKeyDown event ;)
}
return base.ProcessKeyMessage( ref m );
}
Hope it helpful.
