When the user enters a character with the TextBox in focus, I do not want the character to show up on the TextBox at all and I don't want to use the Clear() method as there may be other text in the TextBox I don't want erased. so far I've tried:
private void WriteBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == (char)13) // enter key pressed
{
WriteBox1.Text = "";
}
// Code to write Serial....
String writeValues = WriteBox1.Text;
String withoutLast = writeValues.Substring(0, 1);
WriteBox1.Text = withoutLast;
}
This leaves the last letter entered in writeBox1. I need it to delete all characters entered. I've also tired:
writeValues.Replace(writeValues, "");
WriteBox1.Text = writeValues;
Try setting Handled property on eventargs. Set Handled to true to cancel the KeyPress event. This keeps the control from processing the key press.
example :
private void keypressed(Object o, KeyPressEventArgs e)
{
// The keypressed method uses the KeyChar property to check
// whether the ENTER key is pressed.
// If the ENTER key is pressed, the Handled property is set to true,
// to indicate the event is handled.
if (e.KeyChar == (char)Keys.Return)
{
e.Handled = true;
}
}
