In a user control, I've got a Repeater inside
of an UpdatePanel (which id displayed inside
of a ModalPopupExtender. The Repeater is databound using an array list
of MyDTO objects. There are two buttons for each Item in the list. Upon binding the ImageURL and CommandArgument are set.
This code works fine the first time around but the CommandArgument is wrong thereafter. It seems like the display is updated correctly but the DTO isn't and the CommandArgument sent is the one that has just been removed.
Can anybody spot any problems with the code?
