我有一个理论上应该很简单的问题，但我花了3个小时，现在不能弄清楚。我有一个gridview和lingdatasource，我尝试实现自定义分页。无论我做什么，我似乎都停留在25的页面大小！代码在谢谢！Gridview和linqdatasource的自定义分页

aspx页面

<asp:GridView ID="gvCustomerList" SkinID="StandardGridView" AutoGenerateColumns="false" DataSourceID="LqCustomerSource" 
     AllowPaging="false" AllowSorting="false" PageSize="50" runat="server" OnSorting="gvCustomerList_OnSorting" 
     OnRowCommand="gvSupplierCustomerList_RowCommand"> 
     <Columns> 
      <asp:TemplateField HeaderText="Customer Id" HeaderStyle-HorizontalAlign="Left" SortExpression="CustomerId"> 
       <ItemTemplate> 
        <asp:Label ID="lblCustomerId" runat="server" Text='<%# ((ITB.DAL.LinqObjects.Customer)Container.DataItem).CustomerId %>'></asp:Label> 
       </ItemTemplate> 
      </asp:TemplateField> 
      <asp:TemplateField HeaderText="First Name" HeaderStyle-HorizontalAlign="Left" SortExpression="FirstName"> 
       <ItemTemplate> 
        <asp:Label ID="lblFirstName" runat="server" Text='<%# ((ITB.DAL.LinqObjects.Customer)Container.DataItem).FirstName %>'></asp:Label> 
       </ItemTemplate> 
      </asp:TemplateField> 
      <asp:TemplateField HeaderText="Last Name" HeaderStyle-HorizontalAlign="Left" SortExpression="LastName"> 
       <ItemTemplate> 
        <asp:Label ID="lblLastName" runat="server" Text='<%# ((ITB.DAL.LinqObjects.Customer)Container.DataItem).LastName %>'></asp:Label> 
       </ItemTemplate> 
      </asp:TemplateField> 
      <asp:TemplateField HeaderText="Details" HeaderStyle-HorizontalAlign="Left"> 
       <ItemTemplate> 
        <asp:HyperLink ID="lnkDetails" Text="Details" NavigateUrl='<%# "~/BackOffice/Customers/CustomerDetails.aspx?CustomerId=" + ((ITB.DAL.LinqObjects.Customer)Container.DataItem).CustomerId %>' runat="server" /> 
       </ItemTemplate> 
      </asp:TemplateField> 
      <asp:TemplateField HeaderText="Ask" HeaderStyle-HorizontalAlign="Left"> 
       <ItemTemplate> 
        <asp:HyperLink ID="lnkAsk" Text="Ask" NavigateUrl='<%# "~/BackOffice/Customers/Ask.aspx?CustomerId=" + ((ITB.DAL.LinqObjects.Customer)Container.DataItem).CustomerId %>' runat="server" /> 
       </ItemTemplate> 
      </asp:TemplateField> 

     </Columns> 
    </asp:GridView> 
</div> 
<asp:LinqDataSource ID="LqCustomerSource" AutoPage="false" runat="server" 
OnSelecting="LqCustomerSource_Selecting" AutoSort="False"> 
</asp:LinqDataSource>

代码背后

protected void LqCustomerSource_Selecting(object sender, LinqDataSourceSelectEventArgs e) 
{ 
    try 
    { 
     CustomerDataManager manager = new CustomerDataManager(); 
     string searchName = "";// txtCustomerName.Text.Trim(); 
     int count = 0; 

     List<Customer> customerList = manager.GetSelectedCustomers(gvCustomerList.PageIndex * 50, 50, searchName, SortExpression, SortDirectionForCustomers, out count); 
     //List<CustomerInsuranceInfo> infoList = manager.GetCustomerInsuranceDataFromList(customerList); 
     lblRows.Text = count.ToString(); 

     e.Arguments.StartRowIndex = 0; 
     e.Arguments.MaximumRows = 50; 
     e.Arguments.TotalRowCount = count; 

     if (customerList == null) 
      e.Cancel = true; 
     else 
      e.Result = customerList; 
    } 
    catch (Exception ex) 
    { 
     ApplicationLogBO.Log(ex); 
     // Alert(WebsiteUtil.StandardErrorMessage); 
     e.Cancel = true; 
    } 

}

背后设置的代码好吧，看起来你需要在后面的代码中设置它在LqCustomerSource_Selecting gvCustomerList.PageSize = 50 – user1568656 2012-08-01 14:13:05

好了，它看起来像你需要在LqCustomerSource_Selecting

gvCustomerList.PageSize = 50
