循环数据集而无需回发. [英] looping dataset without postback.

问题描述

一个aspx页面包含2个部分，左边的部分包含静态内容，例如图片.在加载此页面时，我将从sqlserver中与该页面相关的所有数据填充到数据集中.

在基于条件数据集的image1上单击时，需要过滤并显示在页面右侧的网格中.这必须在没有回发的情况下进行.

条件因图像而异.

例如:数据
ID名称URL组
1 A a.aspx 1
2 B b.aspx 1
3 C c.aspx 1
4 D d.aspx 2
5 E e.aspx 2

单击图像1时，网格应在网格中显示A，B，C
单击图像2时的D和E.

最重要的是它应该在没有回发的情况下发生.

关于

One aspx page has 2 sections, left section has static content say images. On load of this page I populate all of the data related to this page from sqlserver into a dataset.

on click of image1 from dataset based on a condition data needs to be filtered and shown in the grid on right hand side of the page. This has to happen without postback.

conditions vary depend on image.

Eg: data
ID Name URL GROUP
1 A a.aspx 1
2 B b.aspx 1
3 C c.aspx 1
4 D d.aspx 2
5 E e.aspx 2

upon click of image 1 the grid should show A,B,C in grid
and D,E when image 2 is clicked.

The most important thing here is it should happen without postback.

推荐答案

最强大的选择AJAX.NET
否则请使用简单的JAVASCRIPT TRY，
"XMLHTTPREQUEST"

FIRST AND THE STRONGEST OPTION AJAX.NET
OTHERWISE USING SIMPLE JAVASCRIPT TRY,
"XMLHTTPREQUEST"

function postdatain_background(var1,var2)
{
    oHttp = window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest();
    oHttp.open("GET","www.yourpage.com?arg1="+var1+"& arg2="+var2, false);
    oHttp.send();
    
}

var1和var2是javascript变量或要回发的自定义元素

var1 and var2 are javascript variables or the custom elements that you want to post back
