Hi,

you can just declare the event handler for the CheckBox control in aspx
(inline in the footer template e.g into the declarative syntax) or another
way is to locate it in ItemCreated of the dataList and wire the event
handler programmaticall y. Both ways work equally.

Hi,

like I said in my previous post, you must do it in *ItemCreated* (it is
different than ItemDataBound). ItemDataBound is not called for footer (only
for normal and alternating items according to the rows in data source), and
it is called only when DataBind is called for the DataList. You need to get
the code to run on every request, and ItemCreated works exactly that way and
additionally ItemCreated is called for the footer as well (DataListItem's
ItemType in ItemCreated is Footer then)

CheckBox; if(d != null)

d.CheckedChange d += new System.EventHan dler(this.Ch_Li ftGround_Checke dChanged); }
