Thanks but on click event of button
protected void Button1_Click(object sender, EventArgs e)
{
DateTime Dob = Convert.ToDateTime(TextBox2.Text);

}

it's showing error as: String was not recognized as a valid DateTime.

you need to change the date format to mm/dd/yyyy.

Solution 2

Use the following regular expression to validate the date in "27/Jan/2011" format and then convert it to datetime.

((3[01]|[12][0-9]|0?[1-9]))([/])(Jan|Feb|Mar|Apr|May|Jun|Jul|Apr|Sep|Oct|Nov|Dec)([/])(\d{4}$)

Please read the question carefully. The op wants the regular expression for dd/MM/yyyy format and not for 27/Jan/2011 format.
