Calling Repeater DataItems

[qwerty]

I have tried to call the Repeater´s item´s DataItem example from Page´s
functions. I have put to the Repeater ID and Name got from the database.

I have tried following:
CType(Repeater( index).DataItem , DataRowView)("I D")

DataBinder.Eval (Repeater(index ).DataItem, "ID")

First get me "NullReferenceE xception" and second zero length string.

Hi qwerty:

Does this happen after you've set a DataSource and called DataBind?

In doing some testing it appears to me the DataItem property is only
valid during the act of data binding. If you add an event handler for
the ItemDataBound event you can dig out the DataRowView, otherwise I
think you'll have to dig into the control hierarchy of the
RepeaterItem to find the string put in place during binding.

Make any sense? Does that help your solution?

Yes, thanks for testing. In my mind didn't came trying events.

I can do what i wanted with ItemDataBound-event using condition
statement to define what item I want to handle.

As a last alternative I would used html controls tag´s attributes.
