                        else
                        {
                            s1 = item.Text;
                            if (string.IsNullOrEmpty(s1))
                                s1 = "NULL";
                            s = s + s1;
                        }
                        i++;
                    }
                }

Where's code for SelectAll?

Lalyka 11-Jun-15 5:50am

I have not written the code, it's a ready asp property that I am using
and I have filled the box with Linq query

CHill60 11-Jun-15 6:10am

ok - what is the linq query?

Lalyka 11-Jun-15 6:12am

List<string> sRet = null;
try
{
IEnumerable<string> q = null;
q = (from a in ListMarkets
orderby a.Name
where a.Market != null
select a.Name).Distinct();

sRet = q.Distinct().ToList();
}
catch (Exception ex)
{
LoggerSoftwareUtility.Error(string.Format("ReportHelper:(ExtractModel) Exception: {0}", ex));
sRet = null;
}
return sRet;

Possibly a silly question - do you have the latest version of that extension, I do know that there have been bug fixes

1.1.0.27408 I downloaded the dll from https://dropdowncheckboxes.codeplex.com/releases/view/70874 but the same problem:/

I just solved it

in case someone has the same problem

in aspx part AddJQueryReference should be true

XML

<asp:DropDownCheckBoxes CssClass="FreeTextFilterSelection" ID="cbMarket" AddJQueryReference="true" UseSelectAllNode="True"
AutoPostBack="true" DataTextField="Text" runat="server" OnSelectedIndexChanged="cbMarket_SelectedIndexChanged" style="height: 19px" >
<Texts SelectBoxCaption="" />
</asp:DropDownCheckBoxes>
