System.Web.UI.WebControls.Repeater and multiple templates

[Robert]

Hi,
if I create a class A with some properies, then create classes B and C
derived from A, later create and ArrayList filled with some B and C items.
This list I would like to use as a datasource for a repeater control. Is it
possible to add more than one <ItemTemplate>? I would like to have i.e two
templates, one for B and second for C object.
I'm using ASP.NET (2.0) very shortly, but I haven't discovered much about
Repeater/Datalist/Datagrid.
Thank you very much.
Robert

Nope.
You can look at Nested Repeaters but afaik you can't have two <ItemTemplate>
sections in the same repeater.

No.

What you can do is have a single item template with a placeholder

<ITemTemplate>
<asplaceHolder id="content" runat="server" />
</ItemTemplate>


Then, in the ItemDataBound event, check which type your DataItem is, and
load the appropriate user control.

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
PlaceHolder content = (PlaceHolder)e.Item.FindControl("content");
if (e.Item.DataItem is B)
{
...
}else...

}
