Question

UpdatePanel very slow?

Asked by: chrisV

Hi Experts,

(sorry about so little points, there my last!)

I have a ListBox within an update panel.

Outside the updatepanel I have a dropDownList and when an item is selected I set a dataTable = the datasourse of my ListBox

When the dataTable has 1000 rows or less it's fast enough but when (and it always does) have > 10,000 rows it takes a loooong time. About 10 times slower then when I don't use an updatePanel

So can the updatePanel only be used when dealing with a small amount of data or is there a work-around? And why is this and is it documented?

Thanks a lot
