You can modify the code in onkeypress event. Modify the value inside

System.Text.RegularExpressions.Regex to suit your need

System.Text.RegularExpressions.Regex rtime = new System.Text.RegularExpressions.Regex(@"[0-2][0-9]\:[0-6][0-9]");

Hi Niradhip,

Thankyou very much...now its working fine...

 But i am using Two Maskedboxes..one maskedbox is minimum Time (06:00:00) and another one masked box Maximum Time ie(30:00:00)...So i need, When i press the key only it should take range validation  for eg ( min time is 06:00:00) and Max time (30:00:00) So how to do..any Regular Expression is their.Please tell me..

You can select the set mask property of the mask textbox and from the mask description you can select the time format.
if you want it to do by coding you can refer the following code:

   private void txtAlerts_KeyPress(object sender, KeyPressEventArgs e)
        {
           
            System.Text.RegularExpressions.Regex rtime = new System.Text.RegularExpressions.Regex(@"[0-2][0-9]\:[0-6][0-9]");
           

                if (!rtime.IsMatch(txtAlerts.Text))
                {

                    MessageBox.Show("Please provide the time in hh:mm format", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);

                 }
           

        }

Note: 'txtAlerts'is the id of my textbox.
