ASP.NET中常用重置数据的方法

aspx：

<asp:Repeater ID="rptProlist" runat="server" onitemdatabound="rptProlist_ItemDataBound">
            <HeaderTemplate>
                <table border="0" class="infolist" cellpadding="0" cellspacing="0">
                    <thead>
                        <tr>
                            <th width="10%">开始日期</th>
                            <th width="7%">创建人</th>
                            <th width="7%">负责人</th>
                            <th width="20%">参与人</th>
                        </tr>
                    </thead>
            </HeaderTemplate>
            <ItemTemplate>
                <tbody>
                    <tr>
                        <td><%#Eval("StartDate","{0:yyyy-MM-dd}")%></td>
                        <td><%#returnUserRealName(Eval("ProjectCreater").ToString())%></td>
                        <td><%#returnUserRealName(Eval("ProjectPrincipal").ToString())%></td>
                        <td><asp:Label ID="lbPlayers" runat="server" Text='<%#Eval("ProjectPlayers") %>'></asp:Label></td>
                    </tr>
                </tbody>
            </ItemTemplate>
            <FooterTemplate>
                </table>
            </FooterTemplate>
        </asp:Repeater>

aspx.cs:

            }
            str = str.Substring(, str.Length - );
            return str;
        }
        protected void rptProlist_ItemDataBound(object sender, RepeaterItemEventArgs e)
