I have a problem to how to catch which key is pressed. This is my code, but i cant get what key was pressed. I'm using KeyEventArgs for declaration of new variable and then comparing it.
private void textBox2_TextChanged(object sender, EventArgs e)
{
KeyEventArgs k = null;
if (e is KeyEventArgs)
{
k = (KeyEventArgs)e;
}
if (k.KeyCode == Keys.Enter)
{
// do something here
}
}
TextChanged
won't give you a KeyEventArgs
. You want KeyUp
, KeyDown
or KeyPress
instead. KeyPress
gives you KeyPressEventArgs
instead.
You need to add:
[component_name].KeyDown += new System.Windows.Forms.KeyEventHandler(this.Key_Pressed_Method);
into the constructor of your Form. Then, you can define what you want to do in Key_Pressed_Method() method.
