Answer 1

试试下面的代码：

protected void grdView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    FillGrid();
    grdView.PageIndex = e.NewPageIndex;
    grdView.DataBind();
}

试试看

在页面加载中

protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        loadGrid();
    }
}

在页面索引更改中

private void loadGrid()
{
    using (your_bankEntities context = new your_bankEntities()) //use your connection .edmx
    {
        var jmDados = (from jm in context.yourdbo  orderby jm.your fieldkey  
                         select new
                           {
                               jm.Field1,
                               jm.Field2,
                               jm.Field3,
                               jm.Field4,
                               ........ 
                               jm.n

                           }).ToList();
        GridView1.DataSource = jmDados;

        GridView1.DataBind();
    }
}

在页面索引更改中

GridView1.PageIndex = e.NewPageIndex;

loadGrid();

Answer 3

您应该在绑定数据之前设置 .PageIndex ！否则，您将需要额外的点击，这实际上会使 BindData 方法调用加倍。以下是我测试过的vb代码。

Private Sub GridViewL_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles GridViewL.PageIndexChanging

    GridViewL.PageIndex = e.NewPageIndex
    BindData()  ' your method to bind data to the grid
End Sub

Answer 4

在 VB.net 中，它与 C# 没有太大区别，您只需删除每行末尾的分号

Private Sub myGridview_PageIndexChanging(sender As Object, e As GridViewPageEventArgs) Handles myGridview.PageIndexChanging

   LoadGridView() //Call your method to load the data into the grid.
   myGridview.PageIndex = e.NewPageIndex
   myGridview.DataBind()

End Sub
