.NET Framework 类库
Control.DataBinding 事件

当服务器控件绑定到数据源时发生。

命名空间:System.Web.UI
程序集:System.Web(在 system.web.dll 中)

语法

Visual Basic(声明)
Public Event DataBinding As EventHandler
Visual Basic(用法)
Dim instance As Control
Dim handler As EventHandler

AddHandler instance.DataBinding, handler
C#
public event EventHandler DataBinding
C++
public:
event EventHandler^ DataBinding {
    void add (EventHandler^ value);
    void remove (EventHandler^ value);
}
J#
/** @event */
public void add_DataBinding (EventHandler value)

/** @event */
public void remove_DataBinding (EventHandler value)
JScript
JScript 支持使用事件,但不支持进行新的声明。
备注

该事件通知服务器控件执行已为其编写的任何数据绑定逻辑。

示例

Visual Basic
' 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 'InstantiateIn

' 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 'BindData 
C#
// Override the ITemplate.InstantiateIn method to ensure

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();
    
}
J#
// Override the ITemplate.InstantiateIn method to ensure

} //InstantiateIn

// Create a public method that will handle the

public void BindData(Object sender, EventArgs e)
{
    Literal l = (Literal)sender;
    DataGridItem container = (DataGridItem)l.get_NamingContainer();
    l.set_Text(((DataRowView)container.get_DataItem()).
        get_Item(column).ToString());
} //BindData
