silverlight使用DataPager实现DataGrid分页

<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>

}

public class Student

public Student(int _studentID, string _studentName)

this.StudentName = _studentName;
}
private int studentID;

public int StudentID
{
get { return studentID; }

public string StudentName

}
}
}

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。
