Chart Trader List Checkbox

[mjairg]

Hi i have this checklist in chart trader, the code for checbox in the grid is this

checkBox1 = new System.Windows.Controls.CheckBox()
{
Margin = new Thickness(5,0,5,0),
Content = "1. Asia Ended",
FontSize = 12,
Foreground = Brushes.Black,
//IsChecked = true,
};

I cant find the way to check when state changes, and save the state, some idea?

Thanks a lot

Hello mjairg,

Assign an event handler method to the .IsEnabledChanged event.

checkBox1.IsEnabledChanged += CheckBox1_IsEnabledChanged;

private void CheckBox1_IsEnabledChanged(object sender, DependencyPropertyChangedEventArgs e)
{

}

Hello mjairg and/or Chelsea,

I'm looking for sample code to create check boxes to my chart trader. The button part I could manage with the code samples available, but sofar the check boxes not yet. Would you be so kind to share the full example code you created to get the check boxes from above? Thanks a lot.

Hello Ducman_nl,

There wasn't any script or sample code created for the answer in post # 2.

This was a direct answer to the question.

That said, the AddonShell example uses a checkbox you may find helpful.

Hi Chelsea,

I have a hard time translating the Addon-Shell sample to some code which adds the check boxes to my Strategy chart Trader. That's why I was looking for an example. A bit like the sample code "SampleWPFModifications" that describes adding the buttons to the chart.

Hello Ducman_nl,

Unfortunately, there isn't an example of this I can provide.

However, similar to adding a button in the SampleWPFModifications example, you can create a new CheckBox object and add this to the ChartTraderGrid ("ChartWindowChartTraderControl").

Hi Chesea,

Worked it out, thanks for your help.

Although I got the check boxes on my chart now, I experience the issue that the event handler is not being triggered. This is how I'm testing it:

protected void CreateWPFControls()
{
for (int i = 0; i < 6; i++) chartTraderCustomCheckBoxesArray[i].IsEnabledChanged += ChartTraderCheckBoxMenu_IsEnabledChanged;
}

protected void ChartTraderCheckBoxMenu_IsEnabledChanged(object sender, DependencyPropertyChangedEventArgs e)
{
CheckBox checkBox = sender as CheckBox;
if (checkBox == chartTraderCustomCheckBoxesArray[0])
{
Draw.TextFixed(this, "infobox", "Chart trader custom Check Box 1", TextPosition.BottomLeft, Brushes.Green, new SimpleFont("Arial", 25), Brushes.Transparent, Brushes.Transparent, 100);
if (checkBox.IsEnabled) Print("checkBox.IsEnabled = " + checkBox.IsEnabled);
}
}

Hello Ducman_nl,

Are you certain the event is not running?

Are you certain the issue is the condition is not evaluating as true?

Add print to the top of the event handler logic block.

Does the print appear in the output window?

Note, to use any series related objects, methods, or properties from a non-data-driven method (like a checkbox .IsEnabledEvent or button .Click event) it is necessary to call TriggerCustomEvent() first. This includes Draw methods which draw over a price series.

Chelsea, I'm quite sure the event is not being triggered. I have put the Print() and Draw() actions at the higest level but nothing happens. I just copied the structure of the Buttons example. Where the Buttons click triggers the Button event, nothing happens when checking or unchecking the CheckBoxes. Maybe you can do a trial?

Hello Ducman_nl,

Thanks for your patience.

The IsEnabledChanged is indeed incorrect. The Checked event is actually correct.
