Scroll issue when adding to DumpContainers and using Util.ReadLine.

sgmoore · July 4

This has been a very,very minor irritation for a long time, but I never have been able to replicate or demo it until now.

When I run this script

var list = Enumerable.Range(1,100).ToList();
Util.AutoScrollResults = true;

var dc = new DumpContainer(list).Dump();

for(int i =0 ; i < 10; i++)
{
    var newValue = Util.ReadLine<int>("Enter Value" , list.Count()+1);
    list.Add(newValue);
    dc.Refresh();
}

it dumps 100 lines and scrolls to show the last entry and correctly realises that Util.Readline takes up the last two lines of the screen. But then when I press return several more times, the last entry is not shown on screen and I need to keep scrolling down to read the details of the last line.

This happens with LP5, LP8 and LP9 , but works correctly with LP4 (4.51.03)

LP9 is not always consistent in how it behaves, sometimes it is one behind and sometimes it is three behind.

Thanks - this should now be fixed in 9.1.6. Updates to DumpContainer will now automatically scroll if a ReadLine is in progress.

Almost.
It is fixed whilst the ReadLine is in effect, but then when it is removed the DumpContainer scrolls down but goes a little too far, meaning I only see the top of the last line.

That's tricky to address, because at that point, the ReadLine is no longer in effect, and so it shouldn't generally scroll as a result of a DumpContainer update.

Interesting,
I managed to get a workaround by adding a dummy container and scrolling into it.

var list = Enumerable.Range(1,100).ToList();
Util.AutoScrollResults = true;

var dc = new DumpContainer(list).Dump();
var dummyDC = new DumpContainer().Dump();

for (int i = 0; i < 10; i++)
{
    var newValue = Util.ReadLine<int>("Enter Value" , list.Count()+1);
    list.Add(newValue);
    dc.Refresh();
    dummyDC.UpdateContent(Util.WithStyle("", "display:none"), true);
}

The last line is always visible even at the end of the script.

Actually the 9.1.6 update seems to have moved this problem from only affecting Util.ReadLines after using DumpContainers to more normal usage, e.g.

Enumerable.Range(1, 100).Dump();
Util.ReadLine("Test");

Works on 9.1.5 and also 8.9.5.

Let me know if this is still an issue in recent updates.
