Hi

I am trying to access several DataItems through the ItemCommand of an Repeater when clicking on a LinkButton e.g

Dim my_id As String
my_id = DataBinder.Eval(e.Item.DataItem, "comp_main_id")

But it gives me always and empty string!

Can anybody help me here?

Thanks, Mike.

you know repeater is not very powerful when you want to use button or ... items which you want it to have action, I prefer datalist because it use the primary key as datakey and therefore you could access all of your items and controls in that datalist.
datalist1.DataKeys.Item(e.Item.ItemIndex)
and something like this... ,

Hi mgasft,

The problem that on ItemCommand even't e.Item.DataItem actually is null. So you can't get value of dataitem.
Walkaround is using of e.Item.Controls property.
For example, if you have lblCompMainID in Repeater you can get value of its Text property:

Dim l1 As Label
l1 = e.Item.Controls .FindControl("lblCompMainID")
'here you have l1.Text

Hi

It seems that the Repeater has no FindControl?
