有时候模糊查询没有反应，怎么回事！

Dim txt As String = e.Sender.Text

Dim dt As DataTable = DataTables("产品列表")

If txt = ""

    dt.LoadFilter = ""

Else

    txt = "'%" & txt & "%'"

    dt.LoadFilter = "产品ID Like " & txt & " Or 缺省供应商 Like " & txt & " Or 销售产品ID Like " & txt & " Or 产品图号 Like " & txt & " Or 产品型号 Like " & txt & " Or 参考代号 Like " & txt & " Or 产品图号 Like " & txt & " Or 产品名称 Like " & txt & " Or 产品材料 Like " & txt & " Or 产品规格 Like " & txt

End If

修改了一下代码，但是查询不到任何内容

Dim txt As String = e.Sender.Text

Dim tbl As DataTable = DataTables("产品列表")

If txt = "" Then

tbl.LoadFilter = ""

Else

txt = "'%" & txt & "%'"

tbl.LoadFilter = "产品ID Like " & txt & " Or 缺省供应商 Like " & txt & " Or 销售产品ID Like " & txt & " Or 类别 Like " & txt & " Or 品牌 Like " & txt & " Or 产品图号 Like " & txt & " Or 产品型号 Like " & txt & " Or 参考代号 Like " & txt & " Or 产品图号 Like " & txt & " Or 产品名称 Like " & txt & " Or 产品材料 Like " & txt & " Or 产品规格 Like " & txt & " Or 外径 Like " & txt & " Or 内径 Like " & txt & " Or 高度 Like " & txt & " Or 产品尺寸 Like " & txt & " Or 备注 Like " & txt

End If

tbl.loadtop = ""

tbl.LoadPage = 0

tbl.load

msgbox("ok")

还出现一个错误

.NET Framework 版本：2.0.50727.8833

Foxtable 版本：2018.8.30.1

错误所在事件：窗口,产品列表,AfterLoad

详细错误信息：

Invalid parameters for Select method.

模糊查询有几种写法，那种比较好呢？

字段里面有百分号%，下面的代码如何更改

Dim txt As String = e.Sender.Text

Dim dt As DataTable = DataTables("产品列表")

If txt = ""

dt.LoadFilter = ""

Else

txt = "'%" & txt & "%'"

dt.LoadFilter = "产品ID Like " & txt & " Or 缺省供应商 Like " & txt & " Or 销售产品ID Like " & txt & " Or 产品图号 Like " & txt & " Or 产品型号 Like " & txt & " Or 参考代号 Like " & txt & " Or 产品图号 Like " & txt & " Or 产品名称 Like " & txt & " Or 产品材料 Like " & txt & " Or 产品规格 Like " & txt

End If

谢谢，如果既有%又有*, 代码如何更改呢？
