GridView分页不能按预期工作

我开始在vb.net上，我必须做一个GridView，它显示从GridView上启用分页的sql查询中的寄存器。但是分页只适用于页面1中的第一个寄存器，当我点击页面2时，它显示的寄存器比它应该少，并且页面数字的条形消失。GridView分页不能按预期工作

我已经看到了类似的问题的人，所有这一切说的是把：

Protected Sub GridView2_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles GridView2.PageIndexChanging 
    GridView2.PageIndex = e.NewPageIndex 
    GridView2.DataBind() 
End Sub

但它似乎没有工作。

下面是用两个可能的查询填充GridView的代码。如果我禁用分页，他们的工作只是罚款，所以这个问题是不是就查询：

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click 


    Dim command As String 
    command = "SELECT [GVA14]. [COD_CLIENT] As Codigo, [GVA14].[RAZON_SOCI] As Nombre,tabla.[periodo] As Cuota FROM [GVA14] LEFT JOIN (SELECT cod_client as cod_client ,MAX(periodo) as periodo FROM emCuotas GROUP BY cod_client) As tabla ON ([GVA14]. [COD_CLIENT] COLLATE DATABASE_DEFAULT=tabla.[cod_client] COLLATE DATABASE_DEFAULT) ORDER BY [GVA14].[COD_CLIENT]" 
    Dim dTable As New DataTable 
    Dim dataAdapter = New OleDbDataAdapter(command, con) 

    dataAdapter.Fill(dTable) 
    GridView2.DataSource = dTable 
    GridView2.DataBind() 
    nro = 1 

End Sub 

Protected Sub Button4_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button4.Click 
    Dim f1 As String 
    f1 = TextBox1.Text 
    Dim f2 As String 
    f2 = TextBox2.Text 
    Dim command As String 
    Dim cuantos As Integer = 50 
    Dim inicio As Integer=0 
    command = "SELECT COD_CLIENT,RAZON_SOCI,FECHA_ALTA FROM GVA14 WHERE FECHA_ALTA BETWEEN CONVERT(datetime,'" & f1 & "',103) AND CONVERT(datetime,'" & f2 & "',103) Order By COD_CLIENT,FECHA_ALTA" 
    Dim dTable As New DataTable 
    Dim dataAdapter = New OleDbDataAdapter(command, con) 
    dataAdapter.Fill(dTable) 
    GridView2.DataSource = dTable 
    GridView2.DataBind() 
    command = "SELECT Count(FECHA_ALTA) FROM GVA14 WHERE FECHA_ALTA BETWEEN CONVERT(datetime,'" & f1 & "',103) AND CONVERT(datetime,'" & f2 & "',103)" 
    Dim comand As New Data.OleDb.OleDbCommand(command, con) 

    Label1.Text = comand.ExecuteScalar 
    nro=2 

End Sub

这里是我做过什么......

Protected Sub gvExistingICByUser_PageIndexChanging(sender As Object, e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gvExistingICByUser.PageIndexChanging 
     Dim grid As GridView = DirectCast(sender, GridView) 
     GetExistingICByUser(CurrentUser) 
     grid.DataSource = dtExistingICByUser 
     grid.PageIndex = e.NewPageIndex 
     grid.DataBind() 
    End Sub

线击穿PageIndexChanging内事件....
1）投你的gridview作为grideview。（我不知道确切Ÿ它这样做的方式，但它的工作瓦特/它，而不是W/O）

2）装入网格视图（我在返回的数据表中的另一功能这样做）

3）设置绑定

非常感谢，它现在有效。 – 2013-05-15 18:17:34

没问题！如果你可以标记为回答！谢谢！ – jharris8567 2013-05-15 21:34:08

删除这些代码行

GridView2.PageIndex = e.NewPageIndex 
GridView2.DataBind()

仅仅指定GridView.PageSize（并允许分页，当然）

做了，并且它也不管用页面索引

4），它只是显示第一页，索引并没有改变。 – 2013-05-10 16:54:31
