ITemplate.InstantiateIn(Control) 方法

定義

命名空間:

System.Web.UI

組件:

System.Web.dll

當類別實作時，定義子控制項和樣板所屬的 Control 物件。 這些子控制項依次定義在內嵌樣板內。

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)

參數

container

Control

包含內嵌樣板之控制項執行個體的 Control 物件。

範例

// 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

備註

開發樣板化伺服器控制項時，您不需要實作此方法;.NET Framework會為您提供實作。
