Question by Frostbite23 · Dec 24, 2018 at 02:11 AM · c#uilists

Dynamically Populated Dropdown list has items with the same text

Hello, upon coding my video settings options menu I ran into a brick wall and it hurt.

So i'm trying to populate a video resolution drop down with the supported video resolutions of the system. Heres the unexpected result

alt text But the odd thing is, checking the dropdowns option list, it has the correct names alt text

so why isin't the items displaying the correct text? heres the code

     //videoSettingsScreen.presetDropdown is a UI.Dropdown

     public void PopulateVideoSettingsScreen()
     {
         Resolution[] resolutions = Screen.resolutions;
         List<string> optionDatas = new List<string>();
 
         foreach (Resolution resolution in resolutions)
         {
             optionDatas.Add(resolution.ToString());
         }
 
         videoSettingsScreen.presetDropdown.ClearOptions();
         videoSettingsScreen.presetDropdown.AddOptions(optionDatas);
     }

EDIT: i've tried instead of list of strings, ive tried dropdown.optiondata and still returning that unexpected result.

Solved the issue, I accidentally unassigned the 'Item Text' property for the Dropdown in the inspector.
