Try this

<asp:CheckBox ID="chkActive" runat="server" Checked='<%# Eval("IsActive ").ToString()=="Flase" ? true : false %>'  />

The string values TRUE and FALSE can be converted to bit values: TRUE is converted to 1 and FALSE is converted to 0.

in update button click 


  string id = string.Empty;
        string itmcod = string.Empty;
        try
        {
            foreach (DataListItem item in DataListSearchResult.Items)
            {
                CheckBox chk = (CheckBox)item.FindControl("chkActive");
                HiddenField ShowcaseID = (HiddenField)item.FindControl("HdnShowcaseID");

                if (chk.Checked==false)
                {
                    id += ShowcaseID.Value +","; 
                }            
            }

       //  Update the records with id  

        }
        catch
        { 

        }

you can also use id in Array format
