Question

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SqlSelectCommand设置ListView，因此当客户端搜索项目时返回0结果我将Sql选择更改为LIKE '%search%'。

这一切都运行正常，但是当你点击第2页时它会恢复原来的sql语句

我使用Label作为标题，我也会根据搜索键动态更改标题以确保数据返回到页面

您可以在此处预览我的网站 http://www.barkingdog.co.za/asp/Search1.aspx

同样的问题在Office页面上，虽然我在sql select中启动了包含数据的页面，但是当我点击例如。经济然后尝试转到第2页它显示原始内容的第2页

提前谢谢

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" />

我只是在你的listview分页中猜测这个问题。在PagePropertiesChanging事件重新绑定listview时，请检查您正在使用的查询，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();
}
