F5将在ASP.Net中重新提交

Question

我有.Net webform的问题，需要你的帮助。我有一个js的模态调用来创建新项目。点击保存，没关系。但是，然后，我按F5，它重新提交并创建新项目相同的力量。 帮我找到解决问题的方法。非常感谢。 ////我的模态

//// js show modal

 function ShowModalCreate() {

////最后代码

 protected void btnCreateLuu_Click(object sender, EventArgs e)
    {
        try
        {

                var entity = new EDMCoQuanBanHanh();

                entity.SoDienThoai = txtCreateSoDienThoai.Text.Trim();
                entity.Email = txtCreateEmail.Text.Trim();
                entity.Fax = txtCreateFax.Text.Trim();
                entity.SoThuTu = Convert.ToInt16(txtCreateSoThuTu.Text);
                BDMCoQuanBanHanh.Insert(entity);

        }
        catch (Exception ex)
        {
            WriteLog.WriteLogEntry("CoQuanBanHanh - btnCreateLuu_Click()", ex);
        }

    }
