inside Wizard1_FinishButtonClick event,
how can I find a value from chkAdd control? The checkbox may be checked by the user. 1 or many.

You need use itemdatabound event of Datalist;

protected void amenityList_ItemDataBound(object sender, DataListItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item ||
              e.Item.ItemType == ListItemType.AlternatingItem)
            {
                CheckBox chk = (CheckBox)e.Item.FindControl("chkAdd");
                if (chk.Checked)
                {
                    Response.Write("chked");
                }
                else
                {
                    Response.Write("not chked");
                }
            }            
        }

To get list of selected checkboxes, you can use some list and add checked values into that list.

Hi CoolDev2014,

Assuming that you are binding amenityList to some datasource, and you need checked items from this datalist on any button click. To get checked items you can use bellow code. Sorry for confusion.

foreach (DataListItem item in amenityList.Items)
            {
                CheckBox chk = (CheckBox)item.FindControl("chkAdd");
                if (chk.Checked)
                {
                    Response.Write("chked <br />");
                }
                else
                {
                    Response.Write("notchked <br />");
                }
            }
