添加新行按钮使用数据表Vb.NET

Question

到GridView控件

请帮我 我想，当点击使用数据表按钮来进入添加新行，我用这个子

在我使用的顶部私人医生为数据行= dt.newrow（），私人DT的数据表，名次为整数

Private Sub AddDataTable 
    User = txtUser.Text 
    Password = txtPass.Text 
    Address = txtAddress.Text 

    'add Row... 
    dr(0) = User 
    dr(1) = Password 
    dr(2) = Address 
    'dt.Rows.Add(dr) 
    dt.Rows.InsertAt(dr, Pos) 
    Pos = Pos + 1 
End Sub 

为了获取事件单击

Private Sub btGet_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btGet.Click 
     dgvUser.DataSource = dt 
    End Sub 

，最后一个添加事件点击

Private Sub btAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btAdd.Click 
     AddDataTable() 
     txtUser.Clear() 
     txtPass.Clear() 
     txtAddress.Clear() 
    End Sub 

结果始终是1行，当我尝试重新添加一个新行它给我一个错误
