複選框列表需要根據DB中保存的值進行檢查

Question

chkTypeofIncident.DataSource = from t2 in   
        dbl.usp_GetIncidentsType().AsQueryable() 
        where t2.IncidentTypeFlag== '2' select t2; 

chkTypeofIncident.DataTextField = "Incidents"; 
chkTypeofIncident.DataValueField = "IncidentsMasterID"; 
chkTypeofIncident.DataBind(); 

我使用LINQ獲取了選定的值。但輸出是總是檢查數據庫中的最後一個值。

var CheckedInc = from t2 in dbl.usp_GetIncidentsTypeDetail(Convert.ToInt32(HiddenIncidentRegisterID.Value)).AsQueryable() 
       select t2; 
foreach(var chk in CheckedInc) 
{      
    chkTypeofIncident.SelectedValue = chk.IncidentsMasterID.ToString(); 
} 

Answer 1

foreach (var chk in CheckedInc) 
{ 
chkTypeofIncident.Items.FindByValue(chk.IncidentsMasterID).Selected = true; 
} 

Answer 2

chkTypeofIncident.SelectedValue = CheckedInc.FirstOrDefault().IncidentsMasterID.ToString(); 
//here you also can use where condition
