GridView分頁無法正常工作

Question

我正在嘗試使用GridView進行分頁，
並且我已經添加了GridView的PageIndexChanging方法，
但第二頁返回空白頁。
我用這段代碼做錯了什么？

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.DataBind();
}

Answer 1

當我添加此時，此問題已解決

private void FillGrid()
{
    GridView1.DataSource = "Query..."
    GridView1.DataBind();
}

並更改：

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    FillGrid();
}

Answer 2

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
       BindGrid();
    }
}
private void BindGrid()
{
    GridView1.DataSource = "Query..."
    GridView1.DataBind();
}
protected void GridView1_PageIndexChanging(object sender,GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    this.BindGrid();
}
