Gallery not populating consistently on embedded app load

Posted on by semosby

I have an embedded app which should load products based on the quote. ModelDrivenFormIntegration.DataSource = [@Quotes}
I collect the price list items, using the Price List from the quote. I then associate the product name and unit name, to columns in the gallery since the Product and Unit are records. I need the product name for a search feature.

When testing the embedded app, the gallery is not loaded consistently. If I navigate away from the page and return to the page using the Back() function, the galleries are populated. Is there a setting I'm missing?

Thanks in advance.

Re: Gallery not populating consistently on embedded app load

I've added logic to display a loading spinner while the data is loading. Form displays after load. Not as consistent as I would hope, but it works most of the time.

Re: Gallery not populating consistently on embedded app load

This is a canvas app embedded in a model driven app by way of control. I followed the MS documentation. I've attached the image. The image shows the app after load. The highlighted area is the result of this formula.
ModelDrivenFormIntegration.Item.Name & " "
& Char(13) & CountA(galProducts.AllItems.Product.Product) & " galProducts"
& Char(13) & CountA(listedProd.Product.Product) & " ListedProd"
& Char(13) & CountA(ListProd.Product.Product) & " ListProd"
& Char(13) & CountA(Productlist1.Product.Product) & " ProductList1"

The quote name populates but the collections do not.

Here are the formulas to build the collections located in the on visible of the form.:
Set(inItem,ModelDrivenFormIntegration);
Set(inQuote,ModelDrivenFormIntegration.Item);
Set(inQuoted,inQuote.'Price List');
UpdateContext({openTimer:true});
/* Get price list items from quote price list */
ClearCollect(Productlist1,
//Filter (
Filter('Price List Items', 'Price List Items (Views)'.'PriceList Products'
,'Price List'.'Price List' = inQuote.'Price List')
);

ClearCollect(listedProd,
Filter(Productlist1,'Price List'.'Price List' = inQuote.'Price List') );
/* Add product name for search function */
ClearCollect(ListProd,
AddColumns(listedProd,"pName",Product.Name,"pUnits",Unit.Name,"pLevel",'Price List'.Name)
);

Re: Gallery not populating consistently on embedded app load

Hi @mosbySE,

Just to understand your setup, do you have a model driven app and you're trying to embed a canvas app in it?

Any chance you could add some pics with the controls and their properties of the gallery?

I'm also going to add a doc on embedding canvas app in model driven apps, just in case you're doing this:

Thank you,
