    Resolved [RESOLVED] Asp.net webforms listbox

    Iíve written an Asp.net webforms app that works well in chrome on my desktop workstation, but in iOS chrome and safari, the listboxes donít render their contents. I know they have contents, as another part of the program (a button) is only enabled if at least one of two listboxes have contents. Has anyone any idea what is happening?

    In iOS my list boxes appear almost disabled in appearance, but I know the items Iím adding are being added to them. Items are still not rendered.

    This is the app. embedded in my webpage...

    Not sure if you still have the issue but,
    I haven't read throughout the code as am in a hurry but if I understand correctly you expect to add items that they don't appear.
    Try using not page.ispostback as a webpage can go in multiple cycles and if you don't handle the postback then the content will re-render.
    Again a quick read as I'm in a hurry.
    Slow as hell.

    Apparently, listboxes don't work the same in ios. Instead of displaying the list onscreen, clicking the listbox brings up a scrollable selecter at the bottom of the screen. I switched to asp:datagrids and an asp:textbox
