从asp.net中的转发器控件中删除图像

Question

我有一个转发器控件来显示图像。在每张图片下方，我都放置了一个用于删除图像的按钮。我希望在按下删除按钮时从转发器控件中删除图像。我到处尝试找到这个，但我没有得到解决方案。提前致谢。 这是我的代码：

<asp:Repeater ID="FileRepeater" runat="server" OnItemCommand="RepeaterCommand">
    <ItemTemplate>
        <div style="float: left; overflow: hidden; display: inline-block;">
            <asp:Image ID="Image1" runat="server" Style="height: 200px; width: 200px; border: 1px solid gray;" ImageUrl="<%# Container.DataItem %>" />
            <br />
            <asp:Button ID="btnDelete" runat="server" Width="80px" Text="Delete" CommandName="delete" UseSubmitBehavior="false" />
        </div>
    </ItemTemplate>
</asp:Repeater>


protected void RepeaterCommand(object source, RepeaterCommandEventArgs e)   
{       
    RepeaterItem itemToRemove = e.Item;
    String sessionItemToRemove = itemToRemove.ToString();
    Console.WriteLine("%c", sessionItemToRemove);
    Session.Remove(sessionItemToRemove);     
}

protected void Page_Load(object sender, EventArgs e)
{
    string[] list = Directory.GetFiles(Server.MapPath("images"));
    List<String> images = new List<string>(list.Count());

    foreach (string item in list)
    {
        images.Add(String.Format("~/Images/{0}", System.IO.Path.GetFileName(item)));
    }

        FileRepeater.DataSource = images;
        FileRepeater.DataBind();

}
