Question

我希望能够根据用户角色显示/隐藏“ div标签”。

有些人会看到某些东西，而其他人则看不到。在中继器之外，这很容易。显然d1.Visible = false;不起作用。

我搜索了包括Stack在内的网络，但无济于事。哪个方向是合适的问题更多。

代码-内联-

protected void Eng_SelectedIndexChanged(object sender, EventArgs e)

{

sqlInv = "Select Item1, Item2, Item3, From Table";

IDataReader reader6 = DatabaseHelper.GetReader(string.Empty, sqlInv);


    Repeater1.DataSource = reader6;

        Repeater1.DataBind();

        reader6.Close();

}

html

asp:Repeater runat="server" id="Repeater1">

itemtemplate>

div>
div id="d1" runat="server"><%# DataBinder.Eval(Container.DataItem, "Item1") %>/div>

<div id="d2" runat="server"><%# DataBinder.Eval(Container.DataItem, "Item2") %>/div>

div id="d3" runat="server"><%# DataBinder.Eval(Container.DataItem, "Item3") %>/div>


/itemtemplate>

/asp:Repeater>


/div>

Answer 1

    <asp:Repeater runat="server" id="Repeater1" OnItemDataBound="Repeater1_ItemDataBound">

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType.Equals(ListItemType.AlternatingItem) || e.Item.ItemType.Equals(ListItemType.Item))
        {
            //You can hide/show disable/enable your div
            Control div1 = e.Item.FindControl("div1");
            //get role here and check 
            // if role != admin 
           div1.Visible = false;
        }
    }

感谢您的回复和指导。在您回复之前，我决定尝试一种非常相似的方法。如下：受保护的void Repeater1_ItemDataBound（object sender，RepeaterItemEventArgs e）

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==       ListItemType.AlternatingItem)
    {




        // Show or hid div here
        System.Web.UI.HtmlControls.HtmlContainerControl div1 = (System.Web.UI.HtmlControls.HtmlContainerControl)e.Item.FindControl("div1");

        System.Web.UI.HtmlControls.HtmlContainerControl div2 = (System.Web.UI.HtmlControls.HtmlContainerControl)e.Item.FindControl("div2");

        System.Web.UI.HtmlControls.HtmlContainerControl div3 = (System.Web.UI.HtmlControls.HtmlContainerControl)e.Item.FindControl("div3");

Also changed the test for the reader.
the reader is checking the DB for a RoleId but the problem was when the reader

为空或为空，页面被炸毁。

I changed to test if the reader had a record or not.
     if (reader6a.Read())
        {
            div1.Visible = true;
            div2.Visible = false;
            div3.Visible = false;
        }
    else
{
and so on
}
