过滤网格问题的网页问题

Question

你好我有网格视图，每页获得10个记录。

问题是，如果我移动到搜索结果的任何其他页面，筛选器将删除并显示所有结果。

protected void Page_Load(object sender, EventArgs e) 
    { 

     if (!IsPostBack) 
     { 
      gridprod.DataSource = d.getprod(); 
      gridprod.DataBind(); 
     } 


    } 

protected void btnsearch1_Click(object sender, ImageClickEventArgs e) 
    { 
     gridprod.DataSource = d.Searchprod(lblfield.SelectedValue, txtsearch.Text); 
     gridprod.DataBind(); 
     gridprod.SelectedIndex = -1; 
    } 

protected void OnPageIndexChanging(object sender, GridViewPageEventArgs e) 
    { 
     gridprod.PageIndex = e.NewPageIndex; 
     gridprod.DataSource = d.getprod(); 
     gridprod.DataBind(); 
    } 

Answer 1

如果您应用一个搜索过滤器，你页面，那么你应该有这样的：

protected void OnPageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
    gridprod.PageIndex = e.NewPageIndex; 
    gridprod.DataSource = d.Searchprod(lblfield.SelectedValue, txtsearch.Text); 
    gridprod.DataBind() 
}
