Asp.net Datapager恢复为原始数据

我创建了一个链接到数据库的搜索页面，当页面加载时，我使用VB Codebehind为

ListView

设置

SqlSelectCommand

，这样当客户端搜索某个项目时，我将Sql选择更改为

如“%search%”

这一切都很好，但当您单击第2页时，它会恢复到原始sql语句

我对标题使用了

标签

，我还根据搜索键动态更改标题，以确保数据返回到页面

你可以在这里预览我的网站

Office页面上也存在同样的问题，虽然我在这里以sql select中的数据开始页面，但当我单击例如economy，然后尝试转到第2页时，它会显示原始内容的第2页

先谢谢你

VB

Protected Sub SearchBox_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles SearchBox.TextChanged
    Dim nval As String
    nval = Searchbox.Text
    BreadCrumb.Text = "Results for " + nval

    AllProductsOff.SelectCommand = "SELECT * FROM [cxpproducts] WHERE [Range]  LIKE '%" & nval & "%'"
End Sub

Protected Sub SearchButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SearchButton.Click
    Dim nval As String
    nval = Searchbox.Text
    BreadCrumb.Text = "Results for " + nval

    AllProductsOff.SelectCommand = "SELECT * FROM [cxpproducts] WHERE [Range]  LIKE '%" & nval & "%'"
End Sub

ASP

  <asp:TextBox ID="SearchBox" runat="server" 
    AutoPostBack="True"></asp:TextBox>

  <asp:Button ID="SearchButton" runat="server" 
    Text="Search" PostBackUrl="./Search1.aspx" style="margin-top: 0px" />

我只是猜测listview分页中存在的问题。请检查在重新绑定页面上的listview PropertiesChange事件时使用的查询，如下所示

protected void ListView1_PagePropertiesChanging(object sender, PagePropertiesChangingEventArgs e)
{
    //set current page startindex, max rows and rebind to false
    lvDataPager1.SetPageProperties(e.StartRowIndex, e.MaximumRows, false);

    //rebind List View
    BindListView();
}
