Component Collection Variable Not Getting Table Info

(0) ShareShare
ReportReport
Posted on by golfnutt82 1,362
Hello,
I am learning components and this attempt to learn isn't working.

I am stuck trying to use a collection to hold table information I can use in a gallery.
In my App Start Screen property I am using the following FX: 
ClearCollect(colNavItems, Table({Text: "Balloons", Screen: 'Balloon Screen',icon: imgBalloon},{Text: "Golf", Screen: 'Golf Screen',icon: imgGolf},{Text: "Automobiles", Screen: 'Automobile Screen',icon:imgCars}));

My Mega Menu Container component uses "Items" custom property
 
When I attempt to use the collection variable in my custom items property, the variable complains.
Can anyone help me with this?

    you're on the right track with using a collection to hold table information for your gallery. Let's troubleshoot and ensure everything is set up correctly.

    1. Collection Initialization: Your ClearCollect function looks correct. It initializes colNavItems with the specified items. Ensure this code is placed in the OnStart property of your app or in a button's OnSelect property for testing purposes.

    2. Gallery Items Property: Make sure your gallery's Items property is set to colNavItems. This binds the collection to the gallery.

    3. Component Custom Property: If your Mega Menu Container component has a custom property named Items, you need to pass colNavItems to this property. For example, if your component is named MegaMenu, you can set its Items property like this:

    MegaMenu.Items = colNavItems

    4. Binding Data to Gallery Controls: Inside your gallery, bind the controls (e.g., labels, images) to the fields in your collection. For example:

    • Set the Text property of a label to ThisItem.Text
    • Set the Image property of an image control to ThisItem.icon

    Here's a step-by-step example:

    1. App OnStart Property:

    ClearCollect(colNavItems, 

        Table(

            {Text: "Balloons", Screen: 'Balloon Screen', icon: imgBalloon},

            {Text: "Golf", Screen: 'Golf Screen', icon: imgGolf},

            {Text: "Automobiles", Screen: 'Automobile Screen', icon: imgCars}

        )

    );

    2.-Gallery Items Property:

    colNavItems

    Component Items Property:

    MegaMenu.Items = colNavItems

    1. Binding Data in Gallery:

      • Label Text property: ThisItem.Text
      • Image Image property: ThisItem.icon
