Nested Repeater - OnItemDataBound - Slow Speed

[Guest]

Hi,

I have a nested repeater. For each row in the parent repeater there is a
child repeater with several rows of data.

The way I'm doing this is throught ItemDataBound Event. So for each Row in
parent repeater, when its ItemDataBound event is raised I grab the content of
the child repeater and DataBind it.

This makes the page load slower if there is more data.

What can I do to speed up the speed of page?

Thanks for your help.

Are you using a DataSet (non or strong typed) .. and you do a .Select to get
the children (or perhaps use the relationship name?)

I'm sure, but lets say you have Orders (parent) and OrderDetails (children)

If you create a OrderCollection (from CollectionBase in 1.1 or a generic in
2.0 ) , and put Order (objects) in that collection
~and you have a Order.Details sub collection (where OrderDetailCollection
is a collection of OrderDetails ) ..

What I'm getting at .. is that if you objects are "pre children-ized",
perhaps it would be faster.

check my blog, I have 1.1 and 2.0 code for creating CollectionBase (1.1) and
a <List> in 2.0.

My theory is that if you pre-childrenize, and avoid the DataSet.Select or
DataSet.GetChildren("myrelationshipname") (sp?)... then it might be faster.

It depends on how motivated you are to setup that test scenario.
