Repeater control and Eval()

[Peter Larsen [CPH]]

Hi,

I was doing some repeater control tests last day, and there was one thing i
couldn't figure out.
Please look at the following sample code:

In the cs file:
string[] s = new string[] { "1", "2" };
repeatertest.DataSource = s;
repeatertest.DataBind();

In the aspx file:
<asp:Repeater ID="repeatertest" runat="server">
<ItemTemplate>
<tr>
<td>
<%#Eval(**** What to write here ****) %>
</tr>
</ItemTemplate>
</asp:Repeater>

I want the Repeater to write out the contents from property "s", but i don't
know how to write the Eval() method.

I am not quite sure but try this: <%# (string)Container.DataItem %,
this should work, at least I have used this way in past but i bound to
may be ArrayList or Table.

Hi Alex,

Thank you for your comment - unfortunately it doesn't work with string
array.
It does know that the first item is "1", but it is not delivered in away
that is acceptable for #Eval.

you use eval when you wany to use refection to access properties of the
dataitem. in ytour case the dataitem is a string and has no usefull
properties, so you should not use eval. follow the above suggestion or if you
don't want a cast:

<%# Container.DataItem.ToString() %>

Hi Peter,

Since the item in the datasource is not a complex class that has column
properties, you should directly reference it via "Container.DataItem". Here
is a complete example:

=========aspx page============
<form id="form1" runat="server">
<div>

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

</div>
</form>
=====================

==========code behind=============
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string[] items = new string[] { "aa", "bb", "cc", "dd" };
Repeater1.DataSource = items;
Repeater1.DataBind();
}
}
====================

Hope this helps.

Sincerely,

Steven Cheng
