移动开发 查询数据 部分数据可以筛选出来 部分数据直接页面显示空白 求解
此主题相关图片如下：11.gif
筛选数据显示页面代码：
Dim e As RequestEventArgs = args(0)
Dim wb As New WeUI
Dim flt As String
If e.GetValues.ContainsKey("unfilter") Then \'如果是取消筛选
wb.ClearCookie() \'清除Cookie
Else
flt = Functions.Execute("getbiaozhang",e, wb) \'根据输入内容合成条件,注意WeUI也需要传递过去
End If
Dim page As Integer = 0 \'默认page为0,显示第一页
Dim pageRows As Integer = 10 \'每页15行
If e.GetValues.ContainsKey("page") Then \'如果地址中有page参数
Integer.TryParse(e.GetValues("page"), page) \'提取page参数
End If
Dim StartRow As Integer = page * pageRows + 1 \'此页第一行
Dim EndRow As Integer = (page + 1) * pageRows \'此页最后一行
\'获取该页数据
Dim cmd As New SQLCommand
cmd.C \'记得设置数据源名称
cmd.CommandText = "Sel ect Count(*) From {表彰}"
If flt > "" Then
cmd.CommandText = cmd.CommandText & " where " & flt
End If
Dim Count As Integer = cmd.ExecuteScalar() \'获取总的行数
Dim Pages As Integer = Math.Ceiling(Count/PageRows) \'计算出总页数
cmd.CommandText = "Sel ect * From (Se lect Row_Number() Over(Order by _Identify) As [NO.],[_Identify],获奖者,获奖名称,授奖单位,获奖时间 From 表彰"
If flt > "" Then
cmd.CommandText = cmd.CommandText & " where " & flt
End If
MessageBox.Show(cmd.CommandText)
cmd.CommandText = cmd.CommandText & ") As a "
cmd.CommandText = cmd.CommandText & " Where [NO.]>= " & StartRow & " And [NO.] <= " & EndRow
\'MessageBox.Show(cmd.CommandText)
Dim dt As DataTable = cmd.ExecuteReader
\'生成菜单
wb.AddPageTitle("","ph1","表彰列表","")
With wb.AddTable("","Table1")
.AfterSelChange = "dynaActiveSheet()" \'置顶选择不同单元格后要执行的js行数,注意区分大小写
.PageNumber = page \'设置页码
.ActiveSheet = "menu" \'设置菜单
.RowHead = 1 \'左边第一列作为行头
.head.AddRow("序号","获奖者","获奖名称","授奖单位","获奖时间")
.ColWidth="1px,30px,55px,20px,10px"
For Each dr As DataRow In dt.DataRows
With .body.AddRow()
.Primarykey =dr("_Identify")
Dim s As String=dr("获奖者")
Dim s1 As String = dr("获奖名称")
Dim s11 As String = dr("授奖单位")
Dim s111 As String = dr("获奖时间")
If s1.Length > 10 Then
s1 = s1.SubString(0,25) & "..."
End If
.AddCells(dr("NO."),s,s1,s11,s111)\'逐个单元格增加
End With
Next
End With
With wb.AddActionSheet("","menu") \'设计菜单
If flt = "" Then
.Add("mnuFilter", "数据筛选","biaozhangchaxun.htm")
Else
.Add("mnuUnFilter", "取消筛选","getbiaozhanglist.htm?unfilter=true")
End If
.Add("mnuCancel","取消","",True)
End With
With wb.AddButtonGroup("","btg2", False)
.Add("btn2", "继续检索","", "biaozhangchaxun.htm")
.Add("btn2", "返回首页","", "default.htm")
If page > 0 Then
.Add("btnPrev", "上一页","","getbiaozhangList.htm?page=" & page - 1)
Else
.Add("btnPrev", "上一页").Kind = 1
End If
If Endrow < count Then
.Add("btnNext", "下一页","","getbiaozhangList.htm?page=" & page + 1)
Else
.Add("btnNext", "下一页").Kind = 1
End If
End With
e.WriteString(wb.Build)

If s1.Length > 10 Then
s1 = s1.SubString(0,10) & "..."
End If
或者
If s1.Length > 25 Then
s1 = s1.SubString(0,25) & "..."
End If
