在asp.net中更新后，Detailsview编辑模式未更改

如何解决在asp.net中更新后，Detailsview编辑模式未更改

我在这里尝试了很多方法。但他们都不在工作。我有一个gridview和detailsview。我使用detailsview数据与sqldatasource绑定，并在后面的代码中更新事件。但是，更新后，编辑模式不会更改为只读。通常，编辑模式在客户端运行。但是当我使用itemupdating时，不会触发modechange。我该如何解决这个问题或我做错了什么？你能帮我吗？

    DetailsView1.DataBind();

protected void DetailsView1_ItemUpdating(object sender,DetailsViewUpdateEventArgs e)
{
    DetailsViewRow row = DetailsView1.Rows[0];
    string status = (row.FindControl("statusDetails") as CheckBox).Checked ? "Active" : "Passive";
    string date = (row.FindControl("date") as Label).Text;

    string update = "UPDATE Purchased_List SET status = '" + status + "',date= '" + date + "'  FROM Purchased_List INNER JOIN UserRegistery ON Purchased_List.user_ID = UserRegistery.Id WHERE (Purchased_List.Id = '" + Gridview1.SelectedValue + "')";
    db.cmd(update);


}

protected void DetailsView1_ItemUpdated(object sender,DetailsViewUpdatedEventArgs e)
{
    DetailsView1.ChangeMode(Detailsviewmode.ReadOnly);
    Gridview1.DataBind();
    DetailsView1.DataBind();
    //e.KeepInEditMode = false;

}

我也尝试了itemcommand，但是没有用。我如何在代码隐藏中触发更改模式

protected void DetailsView1_itemcommand(object sender,DetailsViewCommandEventArgs e)
{
    if (e.CommandName.Equals("Update"))
    {
        this.DetailsView1.DefaultMode = Detailsviewmode.ReadOnly;
        this.DetailsView1.DataBind();
    }

    if (e.CommandName.Equals("Cancel"))
    {
        DetailsView1.ChangeMode(Detailsviewmode.ReadOnly);
        this.DetailsView1.DefaultMode = Detailsviewmode.ReadOnly;
        this.DetailsView1.DataBind();
    }
}
