Handling DataList event from textbox changed

Greetings;

I need to capture the event where the user has changed the value of a textbox in a datalist row. There are no other user interactive controls other than this textbox. There are label controls in the row.

I have a ItemDataBound event routine which performs calculations involving this textbox, however, the new value of the textbox is not picked up by the ItemDataBound event.

Could my error be in expecting to access a changed textbox value defined within an ItemTemplate instead of an EditTemplate? If so, how might I get around this?

Much thanks ... David Bach

itemdatabound only fires when the datalist is bound...so you will lose any user-entered value...
your routine to loop through the datalist has to be in its own subroutine and not involve re-binding the datalist
