Hi friends I am developing an application in which there is a text box, in
this text box I need to have telephone number as an input. So for this I
need to put a constarint on this text box so that it will only accept
integers and not other and also there shold be the c ondition so that no
more than 10 digits could be given....
When I double click on the text box for writing code for the event, the
event which apears is TextChanged event. and after reading several
tutoprials on the google about adding such constraint I found that "*
KeyPress*" event should be used. but when I change this "*TextChange"* to
"KeyPress" in Form1.cs and form1.Designer.cs then also it is not working. I
have also tried to use regular expression but that also didn't work for me.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace WindowsApplication10
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void text1_TextChanged(object sender, EventArgs e)
{
}
}
}
The above is the code
in my form I have defined only two fields one is label and the other is
text box....
Please help me in putting both the constraint..........
