Question

我有一个GridView，我需要做过滤器，在日期和时间之间显示数据。

     <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
    CodeBehind="Default.aspx.cs" Inherits="ExportDataGrid._Default" %>

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
    <style type="text/css">
        #Select1
        {
            width: 109px;
        }
        #Select2
        {
            width: 109px;
        }
    </style>
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <h2>

但这不起作用。我应该如何使用DropList选择合适的时间？宣言好吗？或者应该是不同的？

Answer 1

您可以将AutoPostBack="true" and OnSelectIndexChanged="DropDownList_OnSelectIndexChanged"添加到下拉列表中。

void DropDownList_OnSelectIndexChanged(Object sender, EventArgs e)
 {
    var filter =  DropDownList1.SelectedValue;

    //Request your data with citeria
    //Re-bind your GridView
 }

GridData视图按日期和时间过滤
