Solution 1

Use a Regex.
Pin code:

^\d{6,}$

Mobile:

^\d{10,}$

"how to use regex, please give an example?"
"winforms"

C#

private Regex pinCode = new Regex(@"^\d{6,}$", RegexOptions.Compiled);
private Regex mobileNo = new Regex(@"^\d{10,}$", RegexOptions.Compiled);

private void MyButton_Click(object sender, EventArgs e)
    {
    string input = "123456";
    if (pinCode.IsMatch(input))
        {
        Console.WriteLine("PIN");
        }
    if (mobileNo.IsMatch(input))
        {
        Console.WriteLine("MOBILE");
        }

thanks for reply but i can use following code

C#

private void actxtpincode_Validating(object sender, CancelEventArgs e)
        {
            Validatefivedigits(actxtpincode);
        }
        private void Validatefivedigits(TextBox actxtpincode)
        {
            if (actxtpincode.Text.Length != 6)
            {
                
                errorProvider1.SetError(actxtpincode, "Pincode must be six digits");
            }
            else
            {
              
                errorProvider1.SetError(actxtpincode, "");
            }
        }

Hello ,

you can use Validating Event of that particular TextBox .

and to check the no. of characters, use Length property .

try this

C#

private void txtpin_Validating(object sender, CancelEventArgs e)
        {

            if (txtpin.Text.Length > 6)
            {
                //Error Msg
            }

        }

Remember that Validating event occurs when control is validating.

you can also use TextChanged event of the Textbox . For more details on TextChanged event go through This link

thanks

Solution 5

instead of all this, set MaxLength of the pincode textbox to 6 and mobile to 10 or 11 [11 becuase to accept 0 in begining] and on Leave Event write

if(txtPinCode.Text.Trim().Length < 6)
{
     txtPincode.Focus();
}
