hi,
Please find below code.
this will help you,

foreach (DataListItem dli in costItems.Items)
            {
                if (dli.ItemType == ListItemType.Item || dli.ItemType == ListItemType.AlternatingItem)
                {
                    CheckBox itemCostChk = dli.FindControl("subItemCost") as CheckBox;
                    if (itemCostChk != null)
                    {
                        bool isCostSelected = itemCostChk.Checked;
                    }
                }
            }

Thank but not working. It always returns "FALSE" regardless of it is checked or unchecked.

in the Page_Load method, is there a check on whether the page is a postback or not?

(!Page.IsPostback){
//Populate DataList
}

jeroenemans: the answer is no.

If you can post your codes, that will be very helpful.

There's your problem. You're recreating the checkboxes before reading their checked-property.
Modify your code so it won't rebind on postback, and you're done.

got it. I am able to get the information. But I got one more question if you don't mind.

i have database table below

id desc cost
1 tire 100
2 brake 200

so now i am able to use datalist and checkbox to read the list.
but now I need to capture the checked value in the checkbox and save them into
new table

so if first checkbox is checked, i want to record into the database. can you show me how to do that?
