how to check items in checkboxlist? - asp.net

Question

i have a checkboxlist that i want to check some of it's items,
items that i wanna check store in database, i'm selecting them from database and in a loop i wrote thees but just last item selected :(( :
var selectedRoles = (from r in DataContext.Context.Core_PagesPermission
where r.PageName.Contains(pageName) select r)
.FirstOrDefault();
if(selectedRoles != null)
{
string roles = selectedRoles.Roles;
string[] role = roles.Split(',');
int countTags = role.Count();
foreach (string word in role)
{
CheckBoxList1.SelectedValue = word;
Response.Write(word + "<br/>");
countTags -= 1;
}
}
this worked :
var selectedRoles = (from r in DataContext.Context.Core_PagesPermission where r.PageName.Contains(pageName) select r)
.FirstOrDefault();
dsRoles.DataBind();
CheckBoxList1.DataBind();
if(selectedRoles != null)
{
string roles = selectedRoles.Roles;
string[] role = roles.Split(',');
foreach (string word in role)
{
try
{
CheckBoxList1.Items.FindByValue(word).Selected = true;
}
catch (Exception exp)
{
lbError.Text= exp.ToString();
}

Answer 1

You will want to select the individual items:
CheckBoxList1.Items.FindByText(word).Selected = true;
or
CheckBoxList1.Items.FindByValue(word).Selected = true;
However, if the checkboxlist doesn't have the text/value you are looking for, it will throw an error.

Answer 2

datatable method checkboxlist
for (int i = 0; i < dt.Rows.Count; i++)
{
chkCategories.Items.FindByValue(dt.Rows[i]["CategoryID"].ToString()).Selected = true;
}
