I am binding a List<string>
to a Repeater control. Now I want to use the Eval
function
to display the contents in ItemTemplate
like
<%# Eval("NAME") %>.
But I am not sure what I should use instead of NAME.
Just use <%# Container.DataItem.ToString() %>
If you are worried about null values you may want to refactor to this (.NET 6+)
<asp:Repeater ID="repeater" runat="server">
<ItemTemplate>
<%# Container.DataItem?.ToString() ?? string.Empty%>
</ItemTemplate>
</asp:Repeater>
Note if you are using less than .NET 6 you cannot use the null-conditional operator Container.DataItem?.ToString()
A more complete example based on the LINQ provided by @RobertoBr:
In code behind:
List<string> notes = new List<string>();
notes.Add("Value1")
notes.Add("Value2")
repeaterControl1.DataSource = from c in notes select new {NAME = c};
repeaterControl1.DataBind();
On page:
<asp:Repeater ID="repeaterControl1" runat="server" >
<ItemTemplate>
<li><%# Eval("NAME") %></li>
</ItemTemplate>
</asp:Repeater>
Inside Item Template
<ItemTemplate>
<asp:Label ID="lblName" runat="server" Text='<%# Eval("YourEntityName").ToString() ==""? "NA" : Eval("YourEntityName").ToString()%>'></asp:Label>
<ItemTemplate>
or Simply Add inside Item Template
<%# Eval("YourEntityName").ToString() ==""? "NA" : Eval("YourEntityName").ToString()%>
