adding data grid view rows to sql tables in vb.net

Question

I am trying to add data grid view rows into sql table but this error is showing although real data is saved:

The parameterized query '(@Name1 nvarchar(4000),@Dad nvarchar(4000),@Gender nvarchar(4000' expects the parameter '@Name1', which was not supplied.

I did research a lot, some say to add dbNull value and nothing happened. I also read MSN documents but can't understand enough.

cmd.CommandText = "Insert into Member values('" & txt_fserial_no.Text & "',@Name1,@DOB,@Gender,@Dad,@Relation,@NRC,@Citizen,@Job,@Race,@Country,@Religion)"
cmd.CommandType = CommandType.Text
' Dim adapFam As New SqlDataAdapter'
cmd.Parameters.Add("@Name1", SqlDbType.VarChar)
cmd.Parameters.Add("@Dad", SqlDbType.VarChar)
cmd.Parameters.Add("@Gender", SqlDbType.VarChar)
cmd.Parameters.Add("@DOB", SqlDbType.Date)
cmd.Parameters.Add("@Job", SqlDbType.VarChar)
cmd.Parameters.Add("@Race", SqlDbType.VarChar)

cmd.Parameters.Add("@Country", SqlDbType.VarChar)
cmd.Parameters.Add("@Religion", SqlDbType.VarChar)
cmd.Parameters.Add("@Relation", SqlDbType.VarChar)
cmd.Parameters.Add("@Citizen", SqlDbType.VarChar)
cmd.Parameters.Add("@NRC", SqlDbType.VarChar)

For i As Integer = 0 To datagrid_preview.Rows.Count - 1
    cmd.Parameters.Clear()
    cmd.Parameters.AddWithValue("@Name1", datagrid_preview.Rows(i).Cells(0).Value)
    cmd.Parameters.AddWithValue("@Dad", datagrid_preview.Rows(i).Cells(1).Value)
    cmd.Parameters.AddWithValue("@Gender", datagrid_preview.Rows(i).Cells(2).Value)
    cmd.Parameters.AddWithValue("@DOB", datagrid_preview.Rows(i).Cells(3).Value)
    cmd.Parameters.AddWithValue("@Job", datagrid_preview.Rows(i).Cells(4).Value)
    cmd.Parameters.AddWithValue("@Race", datagrid_preview.Rows(i).Cells(5).Value)
    cmd.Parameters.AddWithValue("@Country", datagrid_preview.Rows(i).Cells(6).Value)
    cmd.Parameters.AddWithValue("@Religion", datagrid_preview.Rows(i).Cells(7).Value)
    cmd.Parameters.AddWithValue("@Relation", datagrid_preview.Rows(i).Cells(8).Value)
    cmd.Parameters.AddWithValue("@Citizen", datagrid_preview.Rows(i).Cells(9).Value)
    cmd.Parameters.AddWithValue("@NRC", datagrid_preview.Rows(i).Cells(10).Value)

    cmd.Connection = conn
    cmd.ExecuteNonQuery()

    'adapFam.InsertCommand.ExecuteNonQuery()'

Next
conn.Close()`][1]

I think this should work:

cmd.CommandText = "Insert into Member(id,Name1,Dad,Gender,DOB,Job,Race,Country,Religion,Relation,Citizen,NRC) values(@id,@Name1,@DOB,@Gender,@Dad,@Relation,@NRC,@Citizen,@Job,@Race,@Country,@Religion)"
cmd.CommandType = CommandType.Text
cmd.Connection = conn

For i As Integer = 0 To datagrid_preview.Rows.Count - 1
    cmd.Parameters.Clear()
    cmd.Parameters.AddWithValue("@id", txt_fserial_no.Text)
    cmd.Parameters.AddWithValue("@Name1", datagrid_preview.Rows(i).Cells(0).Value)
    cmd.Parameters.AddWithValue("@Dad", datagrid_preview.Rows(i).Cells(1).Value)
    cmd.Parameters.AddWithValue("@Gender", datagrid_preview.Rows(i).Cells(2).Value)
    cmd.Parameters.AddWithValue("@DOB", datagrid_preview.Rows(i).Cells(3).Value)
    cmd.Parameters.AddWithValue("@Job", datagrid_preview.Rows(i).Cells(4).Value)
    cmd.Parameters.AddWithValue("@Race", datagrid_preview.Rows(i).Cells(5).Value)
    cmd.Parameters.AddWithValue("@Country", datagrid_preview.Rows(i).Cells(6).Value)
    cmd.Parameters.AddWithValue("@Religion", datagrid_preview.Rows(i).Cells(7).Value)
    cmd.Parameters.AddWithValue("@Relation", datagrid_preview.Rows(i).Cells(8).Value)
    cmd.Parameters.AddWithValue("@Citizen", datagrid_preview.Rows(i).Cells(9).Value)
    cmd.Parameters.AddWithValue("@NRC", datagrid_preview.Rows(i).Cells(10).Value)

    cmd.ExecuteNonQuery()
