37 }
38
39 protected void dlCommodityList_ItemCommand(object source, DataListCommandEventArgs e)
40 {
41 if (e.CommandName == "info")
42 {
43 Response.Redirect("info.aspx?Page=" + this.AspNetPager1.CurrentPageIndex + "&RecordCount=" + this.AspNetPager1.RecordCount + "&commId=" + e.CommandArgument.ToString());
44 }
45 }
46
47 //搜索按钮事件
48 protected void btnSearch_Click(object sender, EventArgs e)
49 {
50
51 string value = txtValue.Text.Replace("", "");
52
53 int key = Convert.ToInt32(ddlKey.SelectedValue);
54
55 switch (key)
56 {
57 case 0:
58 hfValue.Value = " commName LIKE '%" + value + "%' ";
59 break;
60 ......
61 }
62
63 Session.Add("SQL", hfValue.Value);
64 AspNetPager1.CurrentPageIndex = 1;
65 BindDataList(1, this.AspNetPager1.PageSize, Session["SQL"].ToString());
66 }
67
68 protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e)
69 {
70 this.AspNetPager1.RecordCount = MIS.UTIL.MISUtil.GetQueryStringPage("RecordCount");
71 AspNetPager1.CurrentPageIndex = e.NewPageIndex;
72 BindDataList(e.NewPageIndex, this.AspNetPager1.PageSize, Session["SQL"].ToString());
73 }
74
75
76 }
然后在info.aspx页传回Page，RecordCount，UTIL.GetQueryStringPage是处理请求的参数
Response.Redirect("CommodityList.aspx?Page=" + UTIL.GetQueryStringPage("Page") + "&RecordCount=" + UTIL.GetQueryStringPage("RecordCount"));
这样可以实现搜索时,保持原来页面
