如何动态显示和隐藏ASP.NET数据网格中的列 [英] How do I show and hide columns in ASP.NET datagrid dynamically

问题描述

我的DataGrid是这样的：

My DataGrid is something like this:

<pre><asp:DataGrid ID="tasks" runat="server" AutoGenerateColumns="False" GridLines="None">
    <HeaderStyle CssClass="task-list-header"/>
    <ItemStyle  CssClass="task-list-row"/>
    <Columns>
        <asp:BoundColumn DataField="Name"

                         HeaderStyle-Width="100px"

                         HeaderText="Name"></asp:BoundColumn>
        <asp:BoundColumn DataField="Description"

                         HeaderStyle-Width="250px"

                         HeaderText="Description"></asp:BoundColumn>
        <asp:BoundColumn DataField="IsComplete"

                         HeaderStyle-Width="125px"

                         HeaderText="Is Complete"></asp:BoundColumn>
        <asp:TemplateColumn>
            <HeaderStyle Width="75px"/>
            <ItemTemplate>
                <asp:HyperLink ID="Hyperlink1" runat="server"

                    NavigateUrl='<%# ModuleContext.EditUrl("TaskId", Eval("TaskId").ToString(), "EditTask") %>'

                    Text="Edit"></asp:HyperLink>
            </ItemTemplate>
        </asp:TemplateColumn>
        <asp:TemplateColumn>
            <HeaderStyle Width="75px"/>
            <ItemTemplate>
                <asp:LinkButton ID="LinkButton1" runat="server"

                    CommandArgument='<%# Eval("TaskId") %>' CommandName="Delete" Text="Delete"></asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateColumn>
    </Columns>
</asp:DataGrid>

这基本上是最后一个任务列表编辑和删除2列。我正在使用DNN8。如果用户未以超级用户身份登录，我想隐藏编辑和删除链接。我怎么能这样做？



我尝试过：



我使用OnAutoBinding属性尝试了该属性，并在后面的代码中定义了一个函数，但我没有再进一步了。感谢hwlp。

This is basically a list of Task with Last 2 columns as Edit and Delete. I am using DNN8. I want to hide the Edit and Delete links if the user is not logged in as Superuser. How can I do that?

What I have tried:

I tried the property using the OnAutoBinding attribute and defining a function in the code behind but I didn't go any further. Thanks for the hwlp.

推荐答案

bool isSuperUser = checkIsSuperUser();
if (!isSuperUser)
{
    tasks.Columns[3].Visible = false; // edit column index
    tasks.Columns[4].Visible = false; // delete column index
}
