System.Windows.UIElement.IsFocused' cannot be assigned to -- it is read only

[PaulMohn]

I'm getting this error

NinjaScript File Error Code Line Column
Testa.cs Property or indexer 'System.Windows.UIElement.IsFocused' cannot be assigned to -- it is read only CS0200 304 8

From this line

ChartControl.ChartPanels[0].IsFocused = true; 

in this snippet

protected void ChartControl_PreviewKeyDown(object sender, KeyEventArgs e)
{
  // FOCUS on Chart's Window
  TriggerCustomEvent(n =>
  {
    ChartControl.Dispatcher.InvokeAsync((Action)(() =>
    {
      if (Keyboard.IsKeyDown(Key.Insert) && (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl)))
      {
        ChartControl.ChartPanels[0].IsFocused = true;
        ChartControl.ChartPanels[0].Focus();
        Print("0 : " + ChartControl.ChartPanels[0].IsFocused);
      }
    }));

  }, null);
  e.Handled = true; 

While focused (after clicking on panel 0 with the mouse) on ChartControl.ChartPanels[0], it prints as true.

0 : True

I want to set ChartControl.ChartPanels[0].IsFocused to true when pressing Ctrl+Insert while the focus is on a Quantity Selector TextBox.
The purpose is to shift the focus out of the Quantity Selector TextBox back to the Chart Panel.


ChartControl.ChartPanels[0].Focus(); doesn't work.

How can I enable
ChartControl.ChartPanels[0].IsFocused = true; ? Thanks!

Hello PaulMohn,

Thank you for your post.

We document the IsFocused property for ChartPanel, but we do not do so for ChartControl.

I would take a look at this example from a post by one of my colleagues that demonstrates:

https://ninjatrader.com/support/forum/forum/ninjatrader-8/platform-technical-support-aa/1117278-strategy-control-its-ninja-chart-keyboard-focus?p=1117456#post1117456

Please let us know if we may be of further assistance to you.

Hello Kate and many thanks for the direction and interesting fix from Jim.

I just tested the following

protected void ChartControl_PreviewKeyDown(object sender, KeyEventArgs e)
{
  // FOCUS on Chart's Window
  TriggerCustomEvent(n =>
  {
      if (Keyboard.IsKeyDown(Key.Insert) && (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl)))
      {
        if (State == State.Historical)
          return;

      foreach (var window in NinjaTrader.Core.Globals.AllWindows)
      {
        // check if the found window is a Chart window, if not continue looking
        if (!(window is NinjaTrader.Gui.Chart.Chart)) continue;

        window.Dispatcher.InvokeAsync(new Action(() =>
        {
          // try to cast as a Chart, if it fails it will be null
          var foundChart = window as NinjaTrader.Gui.Chart.Chart;

          // make sure we found a chart
          if (foundChart == null) return;

          // make sure the found chart is the owner window
          if (foundChart == this.Owner as NinjaTrader.Gui.Chart.Chart)
          {
            if (foundChart.ActiveChartControl.ChartPanels[ChartPanel.PanelIndex] == ChartPanel)
            {
            ClearOutputWindow();

            foundChart.ActiveChartControl.ChartPanels[0].Focus();
            Keyboard.Focus(foundChart.ActiveChartControl.Chart Panels[0]);

            Print(ChartPanel.IsFocused.ToString());
            Print(foundChart.ActiveChartControl.IsFocused);
            Print(foundChart.ChartTrader.IsFocused);
            Draw.TextFixed(this, "Status", ChartPanel.IsFocused.ToString(), TextPosition.BottomLeft);
            }
          }
        }));
      }
      }

  }, null);
  e.Handled = true; 

Nothing prints when focus is in the Quantity Selector TextBox.

The Focus doesn't shift out of the Quantity Selector Textbox back into the ChartPanel.

Also, nothing prints when focus is on the ChartPanel 0.

Why doesn't it print?
Why doesn't it work?
What fix/next step would you suggest? Thanks!


I printed the following

protected void ChartControl_PreviewKeyDown(object sender, KeyEventArgs e)
{
  // FOCUS on Chart's Window
  TriggerCustomEvent(n =>
  {
      if (Keyboard.IsKeyDown(Key.Insert) && (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl)))
      {
        Print("0 : " + ChartPanel.IsFocused.ToString());

        if (State == State.Historical)
        return;

        Print("1 : " + ChartPanel.IsFocused.ToString());
        foreach (var window in NinjaTrader.Core.Globals.AllWindows)
        {
        Print("2 : " + ChartPanel.IsFocused.ToString());
        // check if the found window is a Chart window, if not continue looking
        if (!(window is NinjaTrader.Gui.Chart.Chart)) continue;

        Print("3 : " + ChartPanel.IsFocused.ToString());
        window.Dispatcher.InvokeAsync(new Action(() =>
        {
        Print("4 : " + ChartPanel.IsFocused.ToString());
        // try to cast as a Chart, if it fails it will be null
        var foundChart = window as NinjaTrader.Gui.Chart.Chart;

        Print("5 : " + ChartPanel.IsFocused.ToString());
        // make sure we found a chart
        if (foundChart == null) return;

        Print("6 : " + ChartPanel.IsFocused.ToString());
        // make sure the found chart is the owner window
        if (foundChart == this.Owner as NinjaTrader.Gui.Chart.Chart)
        {
        Print("7 : " + ChartPanel.IsFocused.ToString());
          if (foundChart.ActiveChartControl.ChartPanels[ChartPanel.PanelIndex] == ChartPanel)
          {
        Print("8 : " + ChartPanel.IsFocused.ToString());
          ClearOutputWindow();
        Print("9 : " + ChartPanel.IsFocused.ToString());

          foundChart.ActiveChartControl.ChartPanels[0].Focus();
          Keyboard.Focus(foundChart.ActiveChartControl.Chart Panels[0]);

        Print("10 : " + ChartPanel.IsFocused.ToString());
          Print(ChartPanel.IsFocused.ToString());
          Print(foundChart.ActiveChartControl.IsFocused);
          Print(foundChart.ChartTrader.IsFocused);
          Draw.TextFixed(this, "Status", ChartPanel.IsFocused.ToString(), TextPosition.BottomLeft);
          }
        }
        }));
        }
      }

  }, null);
  e.Handled = true; 

Result with focus on the ChartPanel 0

0 : True
1 : True
2 : True
2 : True
2 : True
3 : True
2 : True
4 : True
5 : True
6 : True

Result with focus on the Quantity Selector TextBox is there's no prints.

it seems the problematic line is

if (foundChart == this.Owner as NinjaTrader.Gui.Chart.Chart) 

What should I do next? Thanks!

[NinjaTrader_Kate]

Hello PaulMohn,

Thank you for your reply.

I've created a little better example from Jim's code sample in that post I linked. If you run this on, say, a 15 second chart, and put your mouse cursor in the Chart Trader quantity box, you should see that box get unselected when the bar closes, because the focus will shift to the ChartPanel.

Here's an example of the output seen when that occurs:

ChartPanel focused before: False
foundChart.ActiveChartControl focused before: False
foundChart.ChartTrader focused before: False
ChartPanel focused: True
foundChart.ActiveChartControl focused: False
foundChart.ChartTrader focused: False

So this just demonstrates that we are able to focus on the ChartPanel, but not ChartControl.

Please let us know if we may be of further assistance to you.

[PaulMohn]

Thanks Kate for the test and sample.

I did further tests. A short 2min demo

Neither my Quantity Selector located in the Toolbar (1st test) nor the Quantity Selector located in the ChartTrader (2nd test) do focus out.
Only when the cursor is clicked and focused on the Panel 0 does it print.
And it prints true, but the cursor still remains in the quantity Selector box.

For some reason only with the commented out following condition
// if (foundChart == this.Owner as NinjaTrader.Gui.Chart.Chart)
// {
//}
does it prints true.

// FOCUS on Chart's Window
TriggerCustomEvent(n =>
{
if (Keyboard.IsKeyDown(Key.Insert) && (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl)))
{
Print("0 : " + ChartPanel.IsFocused.ToString());

if (State == State.Historical)
return;

Print("1 : " + ChartPanel.IsFocused.ToString());
foreach (var window in NinjaTrader.Core.Globals.AllWindows)
{
Print("2 : " + ChartPanel.IsFocused.ToString());
// check if the found window is a Chart window, if not continue looking
if (!(window is NinjaTrader.Gui.Chart.Chart)) continue;

Print("3 : " + ChartPanel.IsFocused.ToString());
window.Dispatcher.InvokeAsync(new Action(() =>
{
Print("4 : " + ChartPanel.IsFocused.ToString());
// try to cast as a Chart, if it fails it will be null
var foundChart = window as NinjaTrader.Gui.Chart.Chart;

Print("5 : " + ChartPanel.IsFocused.ToString());
// make sure we found a chart
if (foundChart == null) return;

Print("6 : " + ChartPanel.IsFocused.ToString());

// make sure the found chart is the owner window
// if (foundChart == this.Owner as NinjaTrader.Gui.Chart.Chart)
// {

Print("7 : " + ChartPanel.IsFocused.ToString());
if (foundChart.ActiveChartControl.ChartPanels[ChartPanel.PanelIndex] == ChartPanel)
{

Print("8 : " + ChartPanel.IsFocused.ToString());
Print("");
Print("ChartPanel focused before: " + ChartPanel.IsFocused.ToString());
Print("foundChart.ActiveChartControl focused before: " +foundChart.ActiveChartControl.IsFocused);
Print("foundChart.ChartTrader focused before: " +foundChart.ChartTrader.IsFocused);
//ClearOutputWindow();
ChartPanel.Focus();
foundChart.ActiveChartControl.ChartPanels[0].Focus();
Keyboard.Focus(foundChart.ActiveChartControl.Chart Panels[0]);

Print("ChartPanel focused: " + ChartPanel.IsFocused.ToString());
Print("foundChart.ActiveChartControl focused: " +foundChart.ActiveChartControl.IsFocused);
Print("foundChart.ChartTrader focused: " +foundChart.ChartTrader.IsFocused);
Draw.TextFixed(this, "Status", ChartPanel.IsFocused.ToString(), TextPosition.BottomLeft);
}
// }
}));
}
}

}, null);
e.Handled = true;

Any idea what I'm missing?
I don't understand why it would work in your OnBarUpdate method but not in my Ctrl+Insert hotkey.
Would you like my indicator? Here's attached. lines 160-218 is the snippet.

How can I get the cursor to leave the Quantity Selector Box when pressing Ctrl+Insert?
I need it to trigger orders upon other Key Presses (NumPad1, numpad2, NumPad7, NumPad4, Ctral+NumPad7, Ctrl+NumPad4 etc.). Thanks!

[PaulMohn]

Hello Kate,

I've just tested as well your
FocusOnPanelExample.zip (1.8 KB, 1 view) indicator.

Here's a short demo.

As you can see nothing happens nor prints at the 15 seconds close.

Do you get it to work on your end? Thanks!


After new test it works on my end but same as before with commented out
// if (foundChart == this.Owner as NinjaTrader.Gui.Chart.Chart)
// {
// }
demo


But it's still not working on my indicator even with commented out
// if (foundChart == this.Owner as NinjaTrader.Gui.Chart.Chart)
// {
// }

I'll test building it with PreviewKeyDown event from your indicator.

I've tested your script with PreviewKeyDown Event added and it still doesn't work
demo

I tested both with ChartControl and ChartPanel used for the PreviewKeyDown method.

The demo shows that the PreviewKeyDown event works when first focused on the Panel 0, but doesn't work when first focused in the ChartTrader quantity Selector box.

Please find attached the modified scripts:
FocusOnpanelExampletestChartPanel.zip
FocusOnpanelExampletestChartControl.zip

Thank you for your next tip or solution. Thanks!

Hello PaulMohn,

Thank you for your replies.

As with these threads, unfortunately this would be outside the scope of what we could support - we've gone a little outside of that already. I would refer you to Jim and Jesse's comments on these threads, but we'd be unable to further troubleshoot.

Please let us know if we may be of further assistance to you.

[PaulMohn]

Hello Kate and thanks for the reference. I was aware of those other threads that were directed at the ChartControl and I did pursue those suggestions but haven't been able to find a solution.

I've tested Jesse's suggestion with Visual Studio but I don't know how to get all the sub-objects references. Do you have a Visual Studio demo on what to look for? Is it the correct way towards the solution? Why isn't the ChartControl.ChartPanels[0].Focus() enough if it can be focused and is documented as such?

Can you please inform on what to do next as I'm not sure of what to do with the ChartPanel. I understand it does work with the OnBarUpdate method, but not with the PreviewKeyDown method. Why?

I did the testings and it still doesn't make sense.

Why does it focus with the OnbarUpdate but not with the PreviewKeyDown event? How can know? Thanks!

Supposing it is still relevant and still helpful for the ChartPanel issue, what would I need to look for? Thanks!

If the solution is elsewhere/with other sub-objects, where would it be/what other sub-objects would it be? Thanks!

[PaulMohn]

New ideas.
I tested using the Tab key inside the Toolbar and the ChartTrader Quantity Selector box and it does move out of focus, but in spite of that when pressing orders hotkeys when out of the quantity Selector box it does just prompt for the Instrument selector/Timeframe period selector instead.
demo
That suggests it wouldn't be enough even shifting the focus.

Any idea on "disabling the Instrument selector/TimeFrame selector"? What method would I call (the opposite of this request)?

[PaulMohn]

The simple solution was

1x Ctrl+Tab (for The ToolBar Quantity Selector)

Ctrl+Tab 

/

System.Windows.Forms.SendKeys.SendWait("^{TAB}") ; 

and / or

13x Ctrl+Shift+Tab (for The ChartTarader Quantity Selector)

Ctrl+Shift+Tab 

for (int index = 0; index < 14; index++)
{
   System.Windows.Forms.SendKeys.SendWait("^+{TAB}");
} 

demo


I tested pressing a button without success
(the button gets pressed when focused 1st on the Chart Panel,
but it doesn't when 1st focused in the Quantity Selector Box)

I also tested setting the cursor to a position on the Chart / Screen

without success
(the cursor does move to preset position when focused 1st on the Chart Panel,
but it doesn't when 1st focused in the Quantity Selector Box)
