Question

I want to bind the datasource to GridView,but it doesn’t work,because the datasource is dynamic,Who can give me a hand?
Thank you!

/****c#*******/

List<dynamic> dyList = new List<dynamic>();
dynamic info1 = new ExpandoObject();
info1.FFID = 1;
info1.Name = "Bill1";

dynamic info2 = new ExpandoObject();
info2.FFID = 2;
info2.Name = "Bill2";

dyList.Add(info1);
dyList.Add(info2);

Repeater1.DataSource = dyList;
Repeater1.DataBind();

/****aspx*******/

<asp:Repeater ID="Repeater1" runat="server">
        <ItemTemplate>
            <%# Eval("FFID") %> <%# Eval("Name") %>
        </ItemTemplate>
    </asp:Repeater>

Can’t find FFid and Name,Why?

Answer 1

Perhaps if you cast the item to dynamic

<asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
         <%# ((dynamic)Container.DataItem).FFID %>
     </ItemTemplate>
</asp:Repeater>

Or to IDictionary<string, object>. (ExpandoObject implements that)

<asp:Repeater ID="Repeater1" runat="server">
     <ItemTemplate>
          <%# ((IDictionary<string, object>)Container.DataItem)["FFID"] %>
     </ItemTemplate>
</asp:Repeater>
