Acceder a un control dentro de un LayoutTemplate de una ListView
¿Cómo puedo acceder a un Control en el LayoutTemplate
de un control ListView
?
Necesito llegar a litControlTitle
y establecer su atributo Text
.
<asp:ListView ID="lv" runat="server">
<LayoutTemplate>
<asp:Literal ID="litControlTitle" runat="server" />
<asp:PlaceHolder ID="itemPlaceHolder" runat="server" />
</LayoutTemplate>
<ItemTemplate>
</ItemTemplate>
</asp:ListView>
¿Algún pensamiento? Tal vez a través del evento OnLayoutCreated
?

La solución completa:
<asp:ListView ID="lv" OnLayoutCreated="OnLayoutCreated" runat="server">
<LayoutTemplate>
<asp:Literal ID="lt_Title" runat="server" />
<asp:PlaceHolder ID="itemPlaceHolder" runat="server" />
</LayoutTemplate>
<ItemTemplate>
</ItemTemplate>
</asp:ListView>
En codebehind:
protected void OnLayoutCreated(object sender, EventArgs e)
{
(lv.FindControl("lt_Title") as Literal).Text = "Your text";
}

Esta técnica funciona para el diseño de la plantilla; use el evento init del control:
<asp:ListView ID="lv" runat="server" OnDataBound="lv_DataBound">
<LayoutTemplate>
<asp:Literal ID="litControlTitle" runat="server" OnInit="litControlTitle_Init" />
<asp:PlaceHolder ID="itemPlaceHolder" runat="server" />
</LayoutTemplate>
<ItemTemplate>
</ItemTemplate>
</asp:ListView>
Y capturar una referencia al control para su uso en el código detrás (por ejemplo) en el evento de base de datos de ListView:
private Literal litControlTitle;
protected void litControlTitle_Init(object sender, EventArgs e)
{
litControlTitle = (Literal) sender;
}
protected void lv_DataBound(object sender, EventArgs e)
{
litControlTitle.Text = "Title...";
}

Para El Bucle LV Anidado:

Literal litText = lvFirstLevel.FindControl("lvSecondLevel").FindControl("litText") as Literal;
litMainMenuText.Text = "This is test";
}
