Question

这是我的GridView和LinqDataSource

<div id="container">

     <asp:GridView ID="dgvClients" runat="server" OnSelectedIndexChanged="dgvClients_SelectedIndexChanged"
         CssClass="table table-hover table-striped table-condensed" GridLines="None"
         ShowHeaderWhenEmpty="True"
         AutoGenerateColumns="False" AllowPaging="True" DataSourceID="LinqDataSourceClient">
         <Columns>
             <asp:BoundField DataField="accno" HeaderText="Acc No" ReadOnly="True" SortExpression="accno"></asp:BoundField>
             <asp:BoundField DataField="clientname" HeaderText="Client name" ReadOnly="True" SortExpression="clientname"></asp:BoundField>
             <asp:TemplateField HeaderText="Branch" SortExpression="t_branch.branch" >
                 <ItemTemplate>
                     <%# Eval("t_branch.branch")%>
                 </ItemTemplate>
             </asp:TemplateField>
             <asp:BoundField DataField="active" HeaderText="Active" ReadOnly="True" SortExpression="active"></asp:BoundField>
             <asp:BoundField DataField="lastupdated" HeaderText="Last Updated" ReadOnly="True" SortExpression="lastupdated"></asp:BoundField>
         </Columns>
         <Columns>
         </Columns>
         <PagerStyle CssClass="pagination" />
     </asp:GridView>
     <asp:LinqDataSource runat="server" EntityTypeName="" ID="LinqDataSourceClient" ContextTypeName="mcollector.mcollectorDataContext" OrderBy="accno, clientname, branchid" Select="new (accno, clientname, branchid, active, lastupdated, t_branch)" TableName="t_Clients" Where="accno == @accno">
         <WhereParameters>
             <asp:ControlParameter ControlID="TextBoxSearch" PropertyName="Text" DefaultValue="" Name="accno" Type="String"></asp:ControlParameter>
         </WhereParameters>
     </asp:LinqDataSource>
 </div>

我有一个文本框，当它为空时我想显示表中的所有记录。我怎么能这样做？

您可以在LinqDataSource.Selecting Event

中编写逻辑代码

gridview上的数据过滤 - 默认情况下要显示所有记录
