Can EntryElement be multiline on MonoTouch.Dialog?

Question

I subclassed EntryElement and have set the UILineBreakMode in the GetCell method as such:

public class EntryElementEnhanced : EntryElement, IElementSizing
{
    public EntryElementEnhanced(string caption, string placeholder, string value) : base (caption, placeholder, value) {}


    public float GetHeight(UITableView view, NSIndexPath indexPath)
    {
        return 100.0f; //arbitrary number just for testing
    }

    public override UITableViewCell GetCell (UITableView tv)
    {
        var cell = base.GetCell (tv);
        cell.TextLabel.LineBreakMode = UILineBreakMode.WordWrap;
        cell.TextLabel.Lines = 0;


        return cell;
    }
}

This does not seem to make the text that gets entered into the cell word-wrapped. Should I be setting this somewhere else?

If someone knows a better approach, what I'm trying to accomplish at a higher level is I want to create the equivalent of an UITextArea in MonoTouch.Dialog.

EntryElement creates an UITextField which is a one line only control.

If you need multiple lines then I suggest you to create your own Element, e.g. MultilineEntryElement, and have it use a UITextView internally.

You could do this by copy-pasting code from EntryElement or by inheriting from the UIViewElement (or a bit of both).

This seemed to work for me with copying code from the entry element. The only issue that I see now is that in the `GetCell` method from `EntryElement`, `entry.ShouldEndEditing += delegate` tries to reference `root.Sections`. This is an internal list that I can't access in my subclass. Any ideas for a workaround? – valdetero Mar 13 '12 at 22:06

there is a multilineEntryElement code piece at https://gist.github.com/315408

in my app it looks a bit funky but it works.

I created a MultilineEntryElement by subclassing UIViewElement at https://gist.github.com/4080025

Works pretty well and handles a placeholder. You will need to update it for your specific width.

`float containerWidth = UIScreen.MainScreen.Bounds.Width;` – BRogers Apr 03 '13 at 23:17

I'll throw my hat into the ring. I looked at a couple of the multiline entry element gists out there, and they all had layout issues. I wrote this one https://gist.github.com/akcoder/5723722 to address the layout issues and to also handle orientation changes. This should work on all versions of the iPhone and iPad.

You'll have to implement FindControlOfType which is not included in the gist. Also, it does not support a caption, or look nice as an element on the detail side a split view (too wide). It also does not look good being placed in a grouped section, because the text view is rounded (background clear = true) and the placeholder label background is not clear. Thanks for sharing though! – therealjohn Jun 17 '13 at 18:50
Sorry for forgetting to include the FindControlOfType piece. When I tested the code it looked fine in both a grouped and plain view. I'm not sure what happened. I left my previous position so I don't have access to that code anymore so I won't be able to update the gist with the FindControlOfType code :( – Dan Morphis Jun 19 '13 at 17:46
