ChartTrader Call Click Button

[nekroart]

I have this code in "OnStartup" method. I want call the click event of btnMkt from another function. Is this possible?
Now nothing happend.

example: btnMkt.PerformClick();

Button btnMkt;
void clickBuyMKT() {
    btnMkt.PerformClick();
}
protected override void OnStartUp() {
    for (int i = 0; i <= ChartControl.Controls.Count - 1; i++) {
        if (ChartControl.Controls[i] == ChartControl.Controls["pnlChartTrader"]) {
            Panel p = (Panel) ChartControl.Controls["pnlChartTrader"];
            for (int j = 0; j <= p.Controls.Count - 1; j++) {
                if (p.Controls[j] == ChartControl.Controls["pnlChartTrader"].Controls["ctrChartTraderControl"]) {
                    Control ctrader = ChartControl.Controls["pnlChartTrader"].Controls["ctrChartTraderControl"];
                    for (int k = 0; k <= ctrader.Controls.Count - 1; k++) {
                        if (ctrader.Controls[k].Name == "btnBuyMarket") {
                            Button btnMkt = (Button) ctrader.Controls[k];
                        }
                    }
                }
            }
        }
    }
}

Hello nekroart,

Thanks for your post.

We do not have any documentation on triggering UI controls in NT7 and could not offer support for such implementations. For NT8, we would recommend using the AddOn framework.

NT8 AddOn Framework - https://ninjatrader.com/support/help...-us/add_on.htm

When I tested your code, I was getting a Object reference not set to an instance of an object error since the example is setting a local btnMkt instead of the class level button. With this correction btnMkt is not null, however the PerformClick still does not work.

PerformClick looks like the prefered way to trigger win forms buttons, but you may wish to investigate some other approaches as you are experimenting. I've included a StackOverflow link below.

I'll leave this thread open ended for any community members that may have experience in triggering button presses in NinjaTrader 7.

If you have another question involving documented/supported NinjaScript, please feel free to open a new thread.

This is how I find the chart trader buttons in my addon:

Button buyMktButton = parentWindow.FindFirst("ChartTraderControlQuickBuyMarketButton") as Button;
Button sellMktButton = parentWindow.FindFirst("ChartTraderControlQuickSellMarketButton") as Button;​

Then I use WPF automation Ids to invoke them like this:

using System.Windows.Automation;
using System.Windows.Automation.Peers;
using System.Windows.Automation.Provider;​

...
...
ButtonAutomationPeer buyMktButtonPeer = new ButtonAutomationPeer(buyMktButton);
IInvokeProvider buyMktButtonInvokeP = buyMktButtonPeer.GetPattern(PatternInterface.Invoke) as IInvokeProvider;
buyMktButtonInvokeP.Invoke();​
...
