c# - How can I check a DropDownList for containing item in asp.net -

i transfering program wpf asp.net.

i want check dropdownlist if contains item did in wpf way.

else if (!_cbslot3.items.contains("jump") && !_cbslot4.items.contains("jump")) {     foreach (string s in stats2)     {         _cbslot3.items.add(s);         _cbslot4.items.add(s);     } } 

simply checks if not contain jump in 2 dropdown's.

visual studio tells me want listitem instead of string when doing this.

you can use inbuilt function dropdownlist, findbyvalue , findbytext. msdn

you can use - _cbslot3.items.findbyvalue("jump") != null or _cbslot3.items.findbytext("jump") != null .
