Accessing objects inside a tab control

23 Aug 2015, 06:21

Hi everyone,

Full disclosure first of all I am brand new to using Noesis so my XAML's and code is rough to say the least. I am having some trouble accessing some XAML objects that are buried deep in the hierarchy. I dont have much challenge accessing stuff outside of my tab control like this:
NoesisGUIPanel noesisGUI = GetComponent<NoesisGUIPanel>();
		Noesis.FrameworkElement root = noesisGUI.GetContent();

		// Store references to important elements for future use
		waterTankFillBox = (Noesis.Rectangle)root.FindName("WaterTankFill");
		fillText = (Noesis.TextBlock)root.FindName ("WaterFillText");
		gearIcon = (Noesis.Path)root.FindName ("LandingGearIcon");
		fuelBar = (Noesis.Rectangle)root.FindName("FuelBar");
		inGameMenu = (Noesis.Grid)root.GetTemplateChild("GameMenu");
and that works great. However once I try to access something in the hierarchy which is in my tab controller its NULL REFERENCE EXCEPTIONS pouring out the walls. My XAML looks like this:
<UserControl

Re: Accessing objects inside a tab control

Hi and welcome to NoesisGUI community! :)

I've tried to look for all the elements inside the TabControl and I can find them without problem:
public class FindNameBehavior: MonoBehaviour
{
    void Start()
    {
        var gui = GetComponent<NoesisGUIPanel>();
        var content = gui.GetContent(); // content is the root UserControl you posted

        var StoreTabs = (Noesis.TabControl)content.FindName("StoreTabs"); Dump(StoreTabs);
        var StatsBlock = (Noesis.GroupBox)content.FindName("StatsBlock"); Dump(StatsBlock);
        var FuelBox = (Noesis.GroupBox)content.FindName("FuelBox"); Dump(FuelBox);
        var FuelText = (Noesis.TextBlock)content.FindName("FuelText"); Dump(FuelText);
        var WeightBox = (Noesis.GroupBox)content.FindName("WeightBox"); Dump(WeightBox);
        var TotalWeight = (Noesis.TextBlock)content.FindName("TotalWeight"); Dump(TotalWeight);
        var FuelWeight = (Noesis.TextBlock)content.FindName("FuelWeight"); Dump(FuelWeight);
        var WaterWeight = (Noesis.TextBlock)content.FindName("WaterWeight"); Dump(WaterWeight);
        var AircarftWeight = (Noesis.TextBlock)content.FindName("AircarftWeight"); Dump(AircarftWeight);
        var WaterBox = (Noesis.GroupBox)content.FindName("WaterBox"); Dump(WaterBox);
        var WaterVolume = (Noesis.TextBlock)content.FindName("WaterVolume"); Dump(WaterVolume);
        var AmoutToDropSlider = (Noesis.Slider)content.FindName("AmoutToDropSlider"); Dump(AmoutToDropSlider);
        var AmoutToDropText = (Noesis.TextBlock)content.FindName("AmoutToDropText"); Dump(AmoutToDropText);
        var MaximumWaterVolume = (Noesis.TextBlock)content.FindName("MaximumWaterVolume"); Dump(MaximumWaterVolume);
    }

    void Dump(FrameworkElement element)
    {
        if (element != null)
        {
            Debug.Log(string.Format("{0} ({1})", element.GetType().Name, element.Name));
        }
        else
        {
            Debug.Log("null");
        }
    }
} 
No null is dumped to the console.

What function are you using to look for the elements inside the TabControl?
