我有一个中继器，在其 item_command 事件上我绑定了另一个中继器。我想根据第二个中继器中的角色显示数据。为此，我想根据用户的角色隐藏和显示一些列。我们如何使用隐藏代码来做到这一点。提前致谢。我的代码是

<table id="table1" class="yui" cellpadding="0" cellspacing="0">
                <thead>
                    <tr>
                        <th>
                            <a href='#' title="Click Header to Sort">EmpID #</a>
                        </th>
                        <th>Edit</th>
                    </tr>
                </thead>
                <tbody>
                    <asp:Repeater ID="Repaddressorbbl" runat="server" OnItemCommand="Repaddressorbbl_ItemCommand">
                        <ItemTemplate>
                           <tr id="gh" style="cursor: pointer" onclick="Select(this);">
                                <td style="text-align: center;">
                                    <%#Eval("empid")%>
                                </td>  
                                <td>
                                    <asp:LinkButton ID="lknumber" runat="server" Text="Edit" CommandName="searchbybbloraddress" />
                                </td>                             
                            </tr>
                        </ItemTemplate>
                    </asp:Repeater>
                </tbody>
                <tfoot>
                </tfoot>
            </table>

 protected void Repaddressorbbl_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
        if (e.CommandName == "searchbybbloraddress")
        {
          bind_rep2(); 
        }
    }

                <thead>
                    <tr>

                           <tr id="gh" style="cursor: pointer" onclick="Select(this);">
                                <td style="text-align: center;">
                                    <%#Eval("empid")%>

                <tfoot>
                </tfoot>
            </table>

 protected void Repaddressorbbl_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
        if (e.CommandName == "searchbybbloraddress")
        {
          bind_rep2(); 
        }
    }

如果您想从后面的代码中的 ItemCommand 中对第二个转发器进行数据绑定，您有两个选择。

您可以修改设置为第二个转发器的数据源的数据集，并将敏感数据设置为空字符串或**。

您的另一个选择是将 IsVisibleToUser 布尔属性添加到数据集，并在第二个转发器中将 Visible 属性绑定到该属性。

您可以使用生成匿名对象的 Linq 查询轻松修改提供给 DataSource 的数据。

像这样的东西：

Repeater2.DataSource = from d in MyData
                       select new
{
    FirstName = d.FirstName,
    LastName = d.LastName,
    Salary = d.Salary,
    IsVisibleToUser = CurrentUser.IsInRole(...)
}

If you want to databind the second repeater from the ItemCommand in your code behind you have two options.

You could modify the dataset you set as the DataSource of the second repeater and set the sensitive data to an empty string or **.

The other option you have is add a IsVisibleToUser boolean property to your dataset and in your second repeater bind the Visible property to this property.

You can easily modify the data that is given to your DataSource by using a Linq query that produces an anonymous object.

Something like:

Repeater2.DataSource = from d in MyData
                       select new
{
    FirstName = d.FirstName,
    LastName = d.LastName,
    Salary = d.Salary,
    IsVisibleToUser = CurrentUser.IsInRole(...)
}
