示例

以下示例演示如何处理已更改筛选器的事件。 处理程序在显示筛选行之前重置页面索引。

// Handle the filter change event.
protected void OnFilterSelectedIndexChanged(object sender, EventArgs e) {
    // Reset the index of the page to display after 
    // the data filter value has been changed.
    GridView1.PageIndex = 0;
}

' Handle the filter change event.
Protected Sub OnFilterSelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
    ' Reset the index of the page to display after 
    ' the data filter value has been changed.
    GridView1.PageIndex = 0

End Sub

注解

FilterChanged当用户选择外键值时和呈现新值之前，将引发 该事件。 这使你能够提供可以执行自定义操作（如自定义分页）的事件处理方法。
