All form values will be transferred to mail ID ...

Imports System.Net.Mail
    Protected Sub ImageButton1_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton1.Click
        Try
            Dim SmtpServer As New SmtpClient()
            Dim mail As New MailMessage()
            SmtpServer.Credentials = New Net.NetworkCredential("bus@volvobusesindia.com", "pink&777")
            SmtpServer.Port = 25
            SmtpServer.Host = "mail.volvobusesindia.com"
            mail = New MailMessage()
            mail.From = New MailAddress(TextBox12.Text)
            mail.To.Add("bus@volvobusesindia.com")
            mail.Subject = "New Bus Booking Query"
            mail.Body = "Category :" & " " & DropDownList3.SelectedItem.Text
            SmtpServer.Send(mail)
            MsgBox("mail send")
        Catch ex As Exception
            MsgBox(ex.ToString)

    End Sub

In this line:

        mail.Body = "Category:" & " " & DropDownList3.SelectedItem.Text 

You send only the category, you need to add the other information to the Body.

I do not know the names of the fields on your form but you need to change it to something like this:

        mail.Body = "Category:" & " " & DropDownList3.SelectedItem.Text + "<br>" + "Name: " + txtName.Text
