silverlight使用DataPager实现DataGrid分页

1）前台代码

    d:DesignHeight="300" d:DesignWidth="400" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data">


    <Grid x:Name="LayoutRoot" Background="White">
        <!--用StackPanel解决DataGrid和DataPager绑定之后，DataGrid行无法选中。-->
        <StackPanel Orientation="Vertical">
        <data:DataGrid Name="TestDataGrid" AutoGenerateColumns="False">
            <data:DataGrid.Columns>
                <data:DataGridTextColumn Header="StudentID" Binding="{Binding StudentID}">
                </data:DataGridTextColumn>
                <data:DataGridTextColumn Header="StudentName" Binding="{Binding StudentName}">
                </data:DataGridTextColumn>
            </data:DataGrid.Columns>
        </data:DataGrid>
        <data:DataPager Name="TestDataPager"/>
        </StackPanel>
    </Grid>
</UserControl>

            for (int i = 0; i < 20; i++)
            {

            }
            return items;
        }
    }


    public class Student
    {
        public Student(){ }
        public Student(int _studentID,string _studentName)
        {
            this.StudentID = _studentID;
            this.StudentName = _studentName;
        }
        private int studentID;


        public int StudentID
        {
            get { return studentID; }
            set { studentID = value; }
        }
        private string studentName;


        public string StudentName
        {
            get { return studentName; }
            set { studentName = value; }
        }
    }
}

3）个人小结

silverlight使用DataPager实现DataGrid分页是客户端分页，在客户端选择上一页，下一页时是不会连接数据库的。
