Io sto impazzendo...non so come fare a salvare il viewstate di questi benedetti controlli.
Ti posto il codice e vedi se riesci a darmi una mano....
Questo è il mio composite control con supporto al design view.
Praticamente è un pop up contenitore di altri controlli asp.

dalle pagine lo instanzio in questo modo
<%@ Register Assembly="ModalFormPopUp" Namespace="ManagementModalFormPopUp" TagPrefix="PopUpGestDati" %>
<PopUpGestDati:ModalFormContainerControl EnableViewState="true" ID="PanelFormInsUtente" runat="server"
>
<ItemTemplate>
<asp:Panel ID="ContenutoInsUser" runat="server">
<asp:TextBox ID="txt_input" runat="server"></asp:TextBox>
</asp:Panel>
</ItemTemplate>
</PopUpGestDati:ModalFormContainerControl>
Il pop up una volta aperto ha un bottone ok.
Quando viene cliccato ok viene prodotto un postback che ritorna sulla pagina principale.
protected Button SalvaUtente;
protected override void OnInit(EventArgs e)
{
//Generazione Bottoni di Salvataggio
SalvaUtente = new Button();
SalvaUtente.ID = "ButtonSalvaUtente";
SalvaUtente.Text = "OK";
if (Request.Browser.Browser.ToUpper().IndexOf("IE") < 0)
{
SalvaUtente.Style["display"] = "";
}
else
{
SalvaUtente.Style["display"] = "none";
}
PanelBottoniOperazioniDati.Controls.Add(SalvaUtente);
SalvaUtente.Click += new EventHandler(this.SalvaUtente_Click);
base.OnInit(e);
}
protected void SalvaUtente_Click(object sender, EventArgs e)
{
string testo = ((TextBox)PanelFormInsUtente.Controls[0].Controls[0].FindControl("ContenutoInsUser").FindControl("txt_input")).Text;
}
Quando arrivo su SalvaUtente_Click la mia textbox è sempre vuota.
Io lo usercontrol lo ricarico sempre ed ho la prova che dopo il postback della pagina viene richiamato lìevento createchildcontrol.
E allora perchè non salva il viestate dei controlli figli (textbox ad esemio)?.
che cosa devo fare?
Gestire il save e Loadviewstate all'interno del CompositeControl?
Ti prego dammi un idea....
