C# – Detecting a duplicate entry on a textbox, and displaying a message
I have a Winforms application with 2 textboxes and 2 buttons. I would like to use the button to validate if the user has entered an entry in textbox1. If this entry is already present in textbox1, then I would like to display a message in textbox2.
In other words – If the user inputs “123” in textbox1, I want to display a message in textbox2 that says “Error – key already in use”
I have managed to setup a working function as per the following example:
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (!string.IsNullOrWhiteSpace(textBox1.Text) && string.IsNullOrEmpty(textBox2.Text))
{
textBox2.Text = “Error – Key already in use”;
}
else
{
textBox2.Text = string.Empty;
}
}
BUT – this code will also display the error message on button clicks, which is not the behaviour I am looking for. How do I go about doing this?
A:
Your textBox1_KeyPress has to run only once, at form load. Otherwise the user will “lock” the textbox and you’ll never be able to enter any data there.
The other parts of your code (populating textbox2 with the error message and the sending of the error) you can do at form load as well, by also running the code in your form constructor.
It’s not clear from the question if you’re going to be checking more than one textbox or not (such as textBox1 and textBox3) and if the two button presses are the only way to send the message. If you are going to be doing it for more than just those two textboxes, you might be able to ditch the KeyPress event altogether
