I wanted the same thing, but the only way I found to do it was to manually set
the selected element's background color whenever a new selection is made. So I
ended up with the following code. Just get the element from the index path and
call SelectElement() from DvcOnOnSelection().
Element selectedElement = null;
private void SelectElement(StyledStringElement element)
{
if (element != selectedElement)
{
if (selectedElement != null)
{
selectedElement.TextColor = UIColor.Black;
selectedElement.BackgroundColor = UIColor.White;
}
selectedElement = element;
selectedElement.TextColor = UIColor.White;
selectedElement.BackgroundColor = UIColor.Blue;
ReloadData();
}
}

Subject: Re: [MonoTouch] How to keep selected (element)row highlighted
Craig,
Unfortunately, MWC does not use Monotouch.Dialog: it uses its own
UITableView which gives a finer control over things.
My Master is a DialogViewController, which is also available on the
iPhone with some minor conditional stuff, mostly to differentaite
between the iPhone and iPad paradigm.
I can highlight the entry at NSIndexParth.FromRowSection(0,0) at initial
loading time, but fail to keep the selection highlighted whenever an
entry is tapped.
Here's what I've got to handle this:
* in the Dialog Constructor:
if (AppDelegate.IsPad)
Dvc.OnSelection += DvcOnOnSelection;
* and the DvcOnSelection method:
private void DvcOnOnSelection(NSIndexPath nsIndexPath)
{
Dvc.TableView.SelectRow(
Dvc.TableView.IndexPathForSelectedRow,
true,
UITableViewScrollPosition.None);
}
This method is called whenever a row is tapped, but it does not
preserve nor force the selection color.
Any ideas to preserve the selected color in Monotouch.Dialog?
It would be a pity if I had to recode the existing iPhone controller as
a lower level TableViewController on the Ipad...
Thanks in advance,
Guivho.
