问题描述

让我切入正题。我的情况如下：我的自定义字段添加到过滤radgrid控件和过滤完美的作品。问题是当我想用里面radgrid控件EditForm编辑记录。它用来做工精细，但后来我遇到了一些问题，选择合适的行（我总是得到错误的行选择），所以这是我做过什么来解决它。

Let me cut to the chase. My scenario is as follows: I have custom added fields to filter the RadGrid and filtering works perfectly. The problem comes when I want to edit record using EditForm inside RadGrid. It used to work fine, but then I had some problems with selecting the right row (I was always getting the wrong row selected) so this is what I did to fix it.

所以，我带过滤器radgrid控件看起来是这样的：

So, my RadGrid with filters looks like this:

我所做的是使用会话，这将帮助我们后来确定过滤radgrid控件的DataSource启动或它是默认的。

What I did is to use the Session which will help us to determine later if the filtered RadGrid DataSource was initiated or it was the default one.

protected void btnSearch_Click(object sender, EventArgs e)
{
    Session["SearchKontakti"] = "1";
}

之后，我不得不设置preRender如果用循环来检查pviously提到会话$ P $。

After that I had to set PreRender with if loop to check for previously mentioned Session.

protected void gvKontakti_PreRender(object sender, EventArgs e)
{
    int idKontakt = Convert.ToInt32(Request.QueryString["idk"]);

    if (Session["SearchKontakti"] == "1")
    {
        var kontakti = from k in db.Kontakt
                       select k;

        int idTipUsera = Convert.ToInt32(rcbTipUsera.SelectedValue);
        int idTvrtka = Convert.ToInt32(rcbTvrtka.SelectedValue);

        if (rcbTvrtka.SelectedValue != "0")
        {
            kontakti = kontakti.Where(k => k.idFirma == idTvrtka);
        }

        if (rcbTipUsera.SelectedValue != "0")
        {
            kontakti = kontakti.Where(k => k.idOvlasti == idTipUsera);
        }

        if (chkAktivan.Checked == true)
        {
            kontakti = kontakti.Where(k => k.Aktivan == true);
        }
        else
        {
            kontakti = kontakti.Where(k => k.Aktivan == false);
        }

        int idAuthKontakt = Convert.ToInt32(Session["authenticatedUI"]);

        if (idKontakt > 0 && idAuthKontakt == idKontakt)
        {
            gvKontakti.DataSource = from k in kontakti
                                    where k.idKontakt == idKontakt
                                    orderby k.Prezime, k.Ime
                                    select new { Tvrtka = k.Firma.Naziv, k.idKontakt, Naziv = k.Ime + " " + k.Prezime, Funkcija = k.Funkcija, k.Ime, k.Prezime, k.Tel1, k.Tel2, k.Mob1, k.Mob2, k.Email1, k.Email2, k.Fax, k.Adresa1, k.Adresa2, k.Adresa3, k.Grad, k.PostanskiBroj, k.Drzava, k.Biljeske, k.Aktivan, k.Username, k.Password };
        }
        else if (idKontakt > 0 && idAuthKontakt != idKontakt)
        {
            gvKontakti.DataSource = from k in kontakti
                                    where k.idKontakt == idKontakt
                                    orderby k.Prezime, k.Ime
                                    select new { Tvrtka = k.Firma.Naziv, k.idKontakt, Naziv = k.Ime + " " + k.Prezime, Funkcija = k.Funkcija, k.Ime, k.Prezime, k.Tel1, k.Tel2, k.Mob1, k.Mob2, k.Email1, k.Email2, k.Fax, k.Adresa1, k.Adresa2, k.Adresa3, k.Grad, k.PostanskiBroj, k.Drzava, k.Biljeske, k.Aktivan, k.Username, k.Password };
        }
        else
        {
            gvKontakti.DataSource = from k in kontakti
                                    orderby k.Prezime, k.Ime
                                    select new { Tvrtka = k.Firma.Naziv, k.idKontakt, Naziv = k.Ime + " " + k.Prezime, Funkcija = k.Funkcija, k.Ime, k.Prezime, k.Tel1, k.Tel2, k.Mob1, k.Mob2, k.Email1, k.Email2, k.Fax, k.Adresa1, k.Adresa2, k.Adresa3, k.Grad, k.PostanskiBroj, k.Drzava, k.Biljeske, k.Aktivan, k.Username, k.Password };
        }

        gvKontakti.DataBind();
    }
}

所以，这个固定我的首要问题，但给了我一个又一个。我的一些用户控件中包含的UpdatePanel并具有它，每当我尝试短声从radgrid控件我收到以下消息编辑按钮，每个用户控件：无法与ID为UpdatePanel4注销UpdatePanel的，因为它没有使用ScriptManager注册。如果在UpdatePanel从控制树中删除，后来再次添加，这是不支持此可能发生。
参数名：的UpdatePanel

我想知道的是如何解决它。

What I'd like to know is how to fix it.

问候，

推荐答案

我不知道为什么，但不知何故的UpdatePanel 是未注册从 ScriptManger 两次（它发生在 RadGrid.Rebind（）方法太，我被卡住的情况），它是由未注册的第二次ScriptManger你得到无法注销的UpdatePanel ...错误。

I don't know why, but somehow the UpdatePanel is unregistered from the ScriptManger twice (it happens in RadGrid.Rebind() method too; the situation I was stuck in), and the second time it's unregistered from ScriptManger you get the "Cannot unregister UpdatePanel ..." error.

解决方法是注册的UpdatePanel 与 ScriptManger 某处两注销事件之间，使用反射，如这样的：

The workaround is to register the UpdatePanel with the ScriptManger somewhere between the two unregister events, using reflection, like this:

protected void UpdatePanel_Unload(object sender, EventArgs e) {
    MethodInfo methodInfo = typeof(ScriptManager).GetMethods(BindingFlags.NonPublic | BindingFlags.Instance)
        .Where(i => i.Name.Equals("System.Web.UI.IScriptManagerInternal.RegisterUpdatePanel")).First();
    methodInfo.Invoke(ScriptManager.GetCurrent(Page),
        new object[] { sender as UpdatePanel });
}

您应该添加 UpdatePanel_Unload 来在UpdatePanel的 onunload的事件：

you should add the UpdatePanel_Unload to the OnUnload event of the UpdatePanel:

<asp:UpdatePanel ID="UpdatePanel1" runat="server" OnUnload="UpdatePanel_Unload">
