Hello Guys!
I am validating some textboxes but the validations are not working at all:
See Below the code
//validating office Id control
private void textBox2_Validating(object sender, CancelEventArgs e)
{
bool cancel = false;
int number = -1;
if (int.TryParse(this.textBox2.Text, out number))
{
if (Validation.isOfficeId(number))
{
//This control passes validation.
cancel = false;
}
else
{
//This control has failed validation: number is not in the correct format
cancel = true;
this.errorProvider1.SetError(this.textBox2, "You must provide a number wit the format 11ddd!");
}
}
else
{
//This control has failed validation: text box is not a number
cancel = true;
this.errorProvider1.SetError(this.textBox2, "You must provide a valid number!");
}
e.Cancel = cancel;
}
private void textBox2_Validated(object sender, EventArgs e)
{
//Control has validated, clear any error message.
this.errorProvider1.SetError(this.textBox2, string.Empty);
}
//validating office name
private void textBox3_Validating(object sender, CancelEventArgs e)
{
bool cancel = false;
if (string.IsNullOrEmpty(this.textBox3.Text))
{
//This control fails validation: Name cannot be empty.
cancel = true;
this.errorProvider1.SetError(this.textBox3, "You must provide your name!");
}
//else if (!Validation.isOfficeName(textBox3.Text))
//{
// //this control fails validation: name is not in the right ofrma
//}
e.Cancel = cancel;
}
private void textBox3_Validated(object sender, EventArgs e)
{
//Control has validated, clear any error message.
this.errorProvider1.SetError(this.textBox3, string.Empty);
}
//validating office location
private void textBox4_Validating(object sender, CancelEventArgs e)
{
bool cancel = false;
if (!(Validation.isOfficeLocation(textBox4.Text)))
{
//This control fails validation: Name cannot be empty.
cancel = true;
this.errorProvider1.SetError(this.textBox4, "office location must contain atleast one character");
}
e.Cancel = cancel;
}
private void textBox4_Validated(object sender, EventArgs e)
{
//Control has validated, clear any error message.
this.errorProvider1.SetError(this.textBox4, string.Empty);
}
//validating numberOfStaff textBox
private void textBox5_Validating(object sender, CancelEventArgs e)
{
bool cancel = false;
if (!(Validation.isOfficeNumberOfStaff(textBox5.Text)))
{
//This control fails validation: number of staff should be just one digit.
cancel = true;
this.errorProvider1.SetError(this.textBox5, "number of staff should be just one digit!");
}
e.Cancel = cancel;
}
private void textBox5_Validated(object sender, EventArgs e)
{
//Control has validated, clear any error message.
this.errorProvider1.SetError(this.textBox5, string.Empty);
}
//validating officeUnit textBox
private void textBox6_Validating(object sender, CancelEventArgs e)
{
bool cancel = false;
if (!(Validation.isOfficeUnit(textBox6.Text)))
{
//This control fails validation: Name cannot be empty.
cancel = true;
this.errorProvider1.SetError(this.textBox6, "office unit must contain atleast one character");
}
e.Cancel = cancel;
}
private void textBox6_Validated(object sender, EventArgs e)
{
//Control has validated, clear any error message.
this.errorProvider1.SetError(this.textBox6, string.Empty);
}
// validating PayrollNumber textbox
private void textBox7_Validating(object sender, CancelEventArgs e)
{
bool cancel = false;
if (!(Validation.isPayrollNumber(textBox7.Text)))
{
//This control fails validation: payroll Number must contain atleast one character.
cancel = true;
this.errorProvider1.SetError(this.textBox7, "payroll Number must contain atleast one character!");
}
e.Cancel = cancel;
}
private void textBox7_Validated(object sender, EventArgs e)
{
//Control has validated, clear any error message.
this.errorProvider1.SetError(this.textBox7, string.Empty);
}
private void button2_Click(object sender, EventArgs e)
{
//if (Validation.isOfficeId(textBox2.Text) && Validation.isOfficeLocation(textBox4.Text) && Validation.isOfficeName(textBox3.Text)
// && Validation.isOfficeNumberOfStaff(textBox5.Text) && Validation.isOfficeUnit(textBox6.Text) && Validation.isPayrollNumber(textBox7.Text))

if (this.ValidateChildren(ValidationConstraints.Enabled))

SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=mOICISTAFF12;Integrated Security=True");
SqlCommand com;
con.Open();
com = new SqlCommand("INSERT INTO offices VALUES('" + textBox2.Text.Trim() + "','" + textBox3.Text.Trim() + "','" + textBox4.Text.Trim() + "','" + textBox5.Text.Trim() + "','" + textBox6.Text.Trim() + "','" + textBox7.Text.Trim() + "')", con);

else
{
MessageBox.Show("there are invalid controls on the form");
Form1_Load( sender, e);
}The validation class is here:

public static string [] errorMessages = new string[5];

return reg.IsMatch(input);
}
public static Boolean isFirstName(string input)
{
Regex reg = new Regex(@"^[a-zA-Z][a-zA-Z][a-zA-Z]+$");
return reg.IsMatch(input);
}
public static Boolean isOfficeId(int input)
{
Regex reg = new Regex(@"^11[0-9][0-9][0-9]$");
//if (!reg.IsMatch(input.ToString()))
//{
// errorMessages[i] = "the office Id you entered is not in the right format ";

}
