设计一个分页加载窗户口，窗口加一个“TextBox”控件，怎样写代码才能实现模糊查询所有后台数据？主要是数据太多了，全部加载卡的要死。现在的代码只能查询当前页：

Dim txt As String = e.Sender.Text
Dim t As Table = Tables("物资字典")
If txt = ""
    t.Filter = ""
Else
    txt = "\'*" & txt & "*\'"
    t.Filter = "[物资编码] Like " & txt & " Or [上级编号] Like " & txt & " Or [物资名称] Like " & txt & " Or [规格型号] Like " & txt & " Or [计量单位] Like " & txt
End If

Dim txt As String = e.Sender.Text
Dim dt As DataTable = DataTables("物资字典")
If txt = ""
    dt.LoadFilter = ""
Else
    txt = "\'%" & txt & "%\'"
    dt.LoadFilter = "[物资编码] Like " & txt & " Or [上级编号] Like " & txt & " Or [物资名称] Like " & txt & " Or [规格型号] Like " & txt & " Or [计量单位] Like " & txt
End If

dt.Load

输入查询关键字卡的很，一个字一个字的往外蹦

这种要从后台加载的还是不要在textchanged事件中触发  不然超过万行基本上就是崩溃的节奏 用个按钮吧

那么全部的代码如何写呢
