Popup Dialog - Disable Button and Real Time Check

[ExoY]

hello,

I am currently trying to find a way, to dynamically change some aspects of the zos dialog popups.

Specifically, I have a Dialog with a Textbox, and a List of already existing strings. What I would like to achieve is to check the current input of the textbox against the string table, and if it already exists disable the confirm button.

Here is how i currently define the Dialog, and then I just call it with `ZO_Dialogs_ShowDialog(*uniqueId*)`

ESO_Dialogs[uniqueId] = {
        canQueue = true,
        uniqueIdentifier = uniqueId,
        title = {text = "Title"},
        mainText = {text = "Content"},
        editBox = {},
        buttons = {
            [1] = {
                text = SI_DIALOG_CONFIRM,
                callback = function(dialog)
                    local input = ZO_Dialogs_GetEditBoxText(dialog)
                    d(input)
                end,
            },
            [2] = {
                text = SI_DIALOG_CANCEL,
                callback = function()
                       d("cancel")
                end,
            },
        },
}

Does anybody already has experience with that sort of thing or knows of an existing addon that already does it?
