The operands of the '|' operator must be integers or bools and the operands of the '||' operator must be bools.

So these operators don't work with strings and if you want to specify multiple values you need to use them within the string as in my example.

ive tried this piece of code but its not working im just getting a blank result from the query, basicalyy what im trying to achieve is that full time can be any record in the database if its code is 10 or 50 (atleast one, doesn't require both )
DDL3.Items.Add(new ListItem("Full Time","10"|"50");

Well, if you want there to be 2 separate items in the dropdownlist - one for each index then you'll need to give them different text properties which the user will understand. Perhaps:

DDL3.Items.Add(new ListItem("Full Time (10)", "10");
DDL3.Items.Add(new ListItem("Full Time (50)", "50");

However, if you only want there to be one item in the dropdownlist but you want it to have two values, then I'd use:

DDL3.Items.Add(new ListItem("Full Time","10|50");

When retrieving the values you then need to be aware that there could be more than one of them:

string[] values = DDL3.SelectedValue.Split('|');
if (values.Length == 1)
{
// there's only one value, values[0]
}
else
{
// there's two values, values[0] and values[1]
}
