Hi there, I would like to post this simple example of
tryparse method to validate a
textbox. We use two
textboxes and one
button.
The idea is to enter a value in
textbox1 and show the validation result on
textbox2 when the event is fired, a message will appear in the end which will depend on whether we entered a number or alphabet. (I haven't gone as far as validating symbol yet).
I apologize before hand if it turns out there is a better example somewhere in this great forum.
Here's how I wrote the syntax.
private void button1_Click(object sender, EventArgs e)
{
int number2;
if (int.TryParse(textBox1.Text, out number2))
{
textBox2.Text = ("tryparse method succeed");
}
else { textBox2.Text=("value entered is not numeric"); }
}
It's simple and easy, and it just happened its written out there in different examples, I thought I re-post it here, with a little modification.
God bless whoever invented the initial tryparse and those who bother writing down the many examples of
tryparse.
