 Private Sub getrecord()
        Dim dr As System.Data.SqlClient.SqlDataReader
        Dim nic, ecode As String
        Dim st As New SqlClient.SqlCommand("select date_of_arr,no_beds,room_no,name,desig,dept,addr,booked_by,date_of_dept,nicstaff,status,booking_date  from guesthouse where booking_no='" & Trim(bkno.Text) & "' ", conn)
        conn.Open()
        dr = st.ExecuteReader
        nic = ""
        ecode = ""
        If dr.Read() Then
            If dr("status") = "Booked" Or dr("status") = "Pending" Then
                Panelview.Visible = True
                dateofarrival.Text = dr(0).ToString().Substring(0).Remove(9)
                noofbeds.Text = dr(1).ToString
                roomno.SelectedItem.Text = dr(2).ToString
                bookingname.Text = dr(3).ToString
                designation.Text = dr(4).ToString
                department.Text = dr(5).ToString
                address.Text = dr(6).ToString
                ecode = dr(7).ToString
                dateofdeparture.Text = dr(8).ToString().Substring(0).Remove(9)
                nic = dr("nicstaff")
                dateofbooking.Text = dr("booking_date").ToString().Substring(0).Remove(9)
                status.Text = dr("status")
                If nic = "Y" Then
                    requestedby.Visible = False
                    empname.Visible = True
                    ecode = dr(7).ToString
                    dr.Close()
                    pace.Open()
                    Dim dr1 As System.Data.SqlClient.SqlDataReader
                    Dim str As New SqlClient.SqlCommand("select name from apcms_email where empcd='" & Trim(ecode) & "' ", pace)
                    dr1 = str.ExecuteReader
                    staff.SelectedValue = "Y"
                    If dr1.Read() Then
                        empname.SelectedItem.Text = dr1(0).ToString
                    End If
                    pace.Close()
                Else
                    staff.SelectedValue = "N"
                    requestedby.Text = ecode
                End If
            Else
                MsgBox("This Booking No is not valid as the status is " + dr("status"))
            End If
        ElseIf dr.HasRows = False Then
            MsgBox("No Record(s) found for the given criteria!!")
            Call reset()
        End If
            conn.Close()
    End Sub

here the coding is all are correct but the problem is when double clicking the button only it was worked ,,,iwant want to change it into single click

Why do you set the UseSubmitBehavior property of the Button to true? Is there a specific reasone? If no, remove that property.
