asp SqlDataSource Filter Expression; 多个搜索框

Question

我正在尝试对单个数据列执行单个搜索asp:GridView,但是我希望每个列上方有多个过滤器(搜索)框,以便可以在自己的透视列中进行搜索.理论上明确解决这个问题的方法就是拥有多个FilterExpressions.我正在使用VB而且非常新,很容易被VB误解,请使用:

PS.当只有一个过滤器(搜索)框时,我已经让它工作没问题,这当前没有做任何事情

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="xxx" 
    ProviderName="xxxx" 
    SelectCommand="SELECT [ddiID], [volusionID], [Customer], [email], [Total], [SumOfTotal] FROM [BBnewsalesQry] ORDER BY [Customer]"
    FilterExpression="customer like '%{0}%' OR ddiID like '%{0}%'">
      <FilterParameters>
         <asp:ControlParameter Name="ddiID" ControlID="ddiIDSearch" PropertyName="Text" />
         <asp:ControlParameter Name="customer" ControlID="txtSearch" PropertyName="Text" />
      </FilterParameters>
</asp:SqlDataSource>
<div>
   <b>DDI Search:</b> <asp:TextBox ID="ddiIDSearch" runat="server" />
   <b>Customer Search:</b> <asp:TextBox ID="txtSearch" runat="server" />
   <asp:ImageButton ID="btnSearch" ImageUrl="http:xxx" runat="server" />
   <asp:ImageButton ID="btnClear" ImageUrl="http:xxx" runat="server" />
</div>

然后在GridView内部:

<asp:TemplateField HeaderText="ddiID" SortExpression="ddiID">
        <ItemStyle HorizontalAlign="Left" />
           <ItemTemplate>
              <asp:Label ID="lblddiid" Text='<%#HighlightText(Eval("ddiid")) %>' 
                        CssClass="TextField" runat="server" />
           </ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="volusionID" HeaderText="volusionID" ReadOnly="True" SortExpression="volusionID" />
<asp:TemplateField HeaderText="customer" SortExpression="customer">
         <ItemStyle HorizontalAlign="Left" />
           <ItemTemplate>
              <asp:Label ID="lblcustomer" Text='<%#HighlightText(Eval("customer")) %>' 
                        CssClass="TextField" runat="server" />
           </ItemTemplate>
</asp:TemplateField>

您正在引用相同的参数两次 - 请尝试以下操作:

FilterExpression="customer like '%{0}%' OR ddiID like '%{1}%'"
