c# 中DataList中LinkButton的text如何获取，为什么我老得到空值

Question

private void phb_ItemCommand(object source, System.Web.UI.WebControls.DataListCommandEventArgs e)
{
LinkButton rm=(LinkButton)phb.Items(e.Item.ItemIndex).FindControl("lbsm"); 
Page.RegisterStartupScript("","<script language=javascript>alert('"+rm.Text+"');</script>"); 
} 

Answer 1

<asp:datalist id="phb" OnItemCommand="phb_ItemCommand" Runat="server" Width="978"> 
        <ItemTemplate> 
        <table id="Table1" width="980" runat="server" > 
        <tr class="xt"> 
        <td> 
        <%# DataBinder.Eval(Container.DataItem,"orderid")%></td> 
        <td> 
        <%# DataBinder.Eval(Container.DataItem,"employeeid")%> </td>
        <td> 
        <asp:LinkButton Runat="server" ID="lbsm" Text='<%# DataBinder.Eval(Container.DataItem,"customerid")%>'> 
        </asp:LinkButton> 
        </TD> 
        </tr> 
        </table> 
        </ItemTemplate> 
</asp:datalist>
