ObjectDataSource 控制元件

如果使用 ObjectDataSource，幾乎所有內容都已經為你處理，只需簡單地告訴 GridView AllowPaging 並給它一個 PageSize。

<asp:GridView ID="gvColors"
    runat="server"
    DataSourceID="sdsColors"
    AllowPaging="True"
    PageSize="5">
</asp:GridView>

<asp:SqlDataSource ID="sdsColors"
    runat="server"
    ConnectionString="<%$ MyConnectionString %>"
    SelectCommand="SELECT Color_ID, Color_Name FROM Colors">
</asp:SqlDataSource>

手動繫結

如果手動繫結，則必須處理 PageIndexChanging 事件。只需設定 DataSource 和 PageIndex 並重新繫結 GridView。

<asp:GridView ID="gvColors"
    runat="server"
    AllowPaging="True"
    PageSize="5"
    OnPageIndexChanging="gvColors_PageIndexChanging">
</asp:GridView>

C#

protected void gvColors_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    gvColors.DataSource = // Method to retrieve DataSource
    gvColors.PageIndex = e.NewPageIndex;
    gvColors.DataBind();
}

VB.NET

Protected Sub gvColors_PageIndexChanging(sender As Object, e As GridViewPageEventArgs)
{
    gvColors.DataSource = // Method to retrieve DataSource
    gvColors.PageIndex = e.NewPageIndex
    gvColors.DataBind()
}
