ITemplate.InstantiateIn(Control) Metodo

Definizione

Quando viene implementato da una classe, definisce l'oggetto Control al quale appartengono i controlli figlio e i modelli.When implemented by a class, defines the Control object that child controls and templates belong to. I controlli figlio sono a loro volta definiti all'interno di un modello inline.These child controls are in turn defined within an inline template.

public:
 void InstantiateIn(System::Web::UI::Control ^ container);
public void InstantiateIn (System.Web.UI.Control container);
abstract member InstantiateIn : System.Web.UI.Control -> unit
Public Sub InstantiateIn (container As Control)

Parametri

Control

Oggetto Control che deve contenere le istanze dei controlli del modello inline.The Control object to contain the instances of controls from the inline template.

    // Override the ITemplate.InstantiateIn method to ensure 
    // that the templates are created in a Literal control and
    // that the Literal object's DataBinding event is associated
    // with the BindData method.
    public void InstantiateIn(Control container)
    {
        Literal l = new Literal();
        l.DataBinding += new EventHandler(this.BindData);
        container.Controls.Add(l);
    }
    // Create a public method that will handle the
    // DataBinding event called in the InstantiateIn method.
    public void BindData(object sender, EventArgs e)
    {
        Literal l = (Literal) sender;
        DataGridItem container = (DataGridItem) l.NamingContainer;
        l.Text = ((DataRowView) container.DataItem)[column].ToString();

    }
' Override the ITemplate.InstantiateIn method to ensure 
' that the templates are created in a Literal control and
' that the Literal object's DataBinding event is associated
' with the BindData method.
Public Sub InstantiateIn(container As Control) Implements ITemplate.InstantiateIn
   Dim l As New Literal()
   AddHandler l.DataBinding, AddressOf Me.BindData
   container.Controls.Add(l)
End Sub

' Create a public method that will handle the
' DataBinding event called in the InstantiateIn method.
Public Sub BindData(sender As Object, e As EventArgs)
   Dim l As Literal = CType(sender, Literal)
   Dim container As DataGridItem = CType(l.NamingContainer, DataGridItem)
   l.Text = CType(container.DataItem, DataRowView)(column).ToString()
End Sub

Commenti

Quando si sviluppano controlli server basati su modelli, non è necessario implementare questo metodo. il .NET Framework fornisce l'implementazione.When developing templated server controls, you do not need to implement this method; the .NET Framework provides the implementation for you.
