SetChildNeedsDisplay(); .SetNeedsDisplay();

[GronbergInfo]

Hi. i hav ejust started noticing that listview does not update with new lines.
I add a list as Setsource to a listview, adding a bunch of rows into that list, only time the Listview updates/redraw is when i actually click on it in the console.

I have tried to add a bunch of lines and then run both SetChildNeedsDisplay(); .SetNeedsDisplay(); for my listview, and it still only updates the new lines when i click the object it self.

Is there a setting or something for the whole view that i can run re-draw/update everything?

That is a old issue when a view is been updating from a thread it's needed to call the main thread with Application.Mainloop.Invoke(() => myLV.SetNeedsDisplay());. You are only setting the SetNeedsDisplay and when you click on the console the mainloop runs and update the ListView.

Hi.
As a test, i added "Application.MainLoop.Invoke(() => )" on basically anything that touches the UI, but i still dont get any UI update until i click something in the console.

Take this an one of the example that does not show until i click on the main window letting the main thread run:

 if (!port.IsOpen)
            {
                port = new SerialPort(settings.ServerSettings.ComSelection, settings.ServerSettings.BaudRate, settings.ServerSettings.ComParity, settings.ServerSettings.Datasize, settings.ServerSettings.StopBits);
                Application.MainLoop.Invoke(() => lstServerLogsList.Add("COM Server settings:"));
                Application.MainLoop.Invoke(() => lstServerLogsList.Add("COM Port: " + settings.ServerSettings.ComSelection));
                Application.MainLoop.Invoke(() => lstServerLogsList.Add("Baud rate: " + settings.ServerSettings.BaudRate));
                Application.MainLoop.Invoke(() => lstServerLogsList.Add("Parity: " + settings.ServerSettings.ComParity));
                Application.MainLoop.Invoke(() => lstServerLogsList.Add("Data Size: " + settings.ServerSettings.Datasize));
                Application.MainLoop.Invoke(() => lstServerLogsList.Add("Stop Bits: " + settings.ServerSettings.StopBits));
                Application.MainLoop.Invoke(() => lstServerLogsList.Add("---"));


                // Attach a method to be called when there
                // is data waiting in the port's buffer
                Application.MainLoop.Invoke(() => lstServerLogsList.Add("Incoming Data:"));
                port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived);
                // Open the port for communications
                port.Open();

            }

You are forgetting the most essential that is call the SetNeedsDisplay(). You don't need call Application.MainLoop.Invoke for each added items in the list. You only need use it at end to call the SetNeedsDisplay() from your ListView.
