in the examples (and in my project code) the RadDataForm has a 30-40 pixel gap at the top.  

You can see it when you set the background color to something other than white (see image).

How do I eliminate that?

Hi Scott,

Thank you for contacting us.

There is an issue in the native iOS data where a group header is visible even if no groups are specified. I have logged it in our feedback portal where you can track its status.

You can hide the group header in the iOS data form renderer where you can create a custom delegate and override the UpdateGroupView method to hide the title.

public class CustomDFRenderer : DataFormRenderer
{
    protected override TKDataFormDelegate GetDataFormDelegate(TKDataForm form)
    {
        return new CustomDFDelegate(this);
    }
}
 
public class CustomDFDelegate : DataFormDelegate
{
    public CustomDFDelegate(CustomDFRenderer renderer) : base(renderer)
    {
    }
 
    public override void UpdateGroupView(TKDataForm dataForm, TKEntityPropertyGroupView groupView, uint groupIndex)
    {
        base.UpdateGroupView(dataForm, groupView, groupIndex);
        groupView.TitleView.Hidden = true;
    }
}

And don't forget to add the following assembly attribute to register the custom renderer:
[assembly: ExportRenderer(typeof(RadDataForm), typeof(CustomDFRenderer))]

Please, let us know if you have further questions.
