Adding specified value to a check-box list while binding a set of data's

Question

Am binding a set of values into a Check box list through Linq-To-Sql concept,by giving data source and data bind,but with those values i need to also bind a value "Other". Is there any way to bind ..??

The DataSource which i have given to the Checkbox List,

ddlcustom2.DataTextField = "SUB";
ddlcustom2.DataValueField = "CLASS";
ddlcustom2.DataSource = _lst;
ddlcustom2.DataBind();

where _lst has a set of records,and its the source which i have given to the Checkbox List.

ddlcustom2.Items.Add(new ListItem("None", "00000000-0000-0000-0000-000000000000"));
ddlcustom2.Items.Insert(0,new ListItem("None", "00000000-0000-0000-0000-000000000000"));
ddlcustom2.Items.Add("None");

And i also tried these stuffs.additional to the list of values i need to also bind "NONE" to the checkbox list .is it possible..??

Answer 1

make sure that you have configured AppendedDataboundItems=true in Drop downlist

Or

You just need to add None record in _lst before binding to drop down list.

_lst.Add ( new classname { "None","000000"} );

ddlcustom2.DataTextField = "SUB";
ddlcustom2.DataValueField = "CLASS";
ddlcustom2.DataSource = _lst;
ddlcustom2.DataBind();
