How to – Set Default value for the combo box in Canvas Apps (Dataverse)

Suppose we have the following Combo Box named Status bind to one of the choice fields of Dataverse.

Items = Asset Status option set field of table Product.

Now if we want Available to be the default selected value for it, we can use the DefaultSelectedItems property of the combo box.

DefaultSelectedItems = Filter(Choices(Products[@’Asset Status’]), Value = ‘Asset Status’.Available)

Also if we want to set the value of the Villages combo box based on the value selected in the Region combo box. The region is a lookup field in the Villages table.

We can update the Items property of the Villages combo box from

Villages (Data Source)

If(IsBlank(comboRegion.Selected),Villages, Filter(Villages, Region.Region = comboRegion.Selected.Region))

Hope it helps..

Format property missing in Date Picker in custom page – Dataverse / PowerApps

Recently while designing the custom page, we realized that the format property is missing for the Date Picker control. This is because Date Picker control is based on Fluent UI Library.

One option earlier was to enable the Classic Controls from Settings

And replace the existing control with the classic control

Sample formula for Associating N:N records and Creating 1:N records in Canvas App (PowerApps / Dataverse)

Just sharing the sample formula, we used for associating selected products from the gallery to lead on OnSelect of a button.

Here collectionCheckedProducts contains the checked products from the gallery bound to the product data source –

varEnquiryIdWithoutCurlyBraces contains the GUID of the Lead record. Here Enquiry is Lead renamed.

Enquires(leadproduct_association) is the name of the relationship between lead and product.

Relate function is used to associate multiple selected products in collectionCheckedProducts to a lead record.

And below is the sample formula we used for creating Quote Product for selected products from the gallery.

varEnquiryIdWithoutCurlyBraces contains the GUID of the Quote record. Proposal Data Source is the Quote renamed.

Hope it helps..

How to – Filter using related table(lookup)’s Multi Choices or MultiSelect Option Set column– PowerApps / Dataverse / Dynamics 365

Continuing our previous example, here we have added a new choice field in Table B.

Here Table A has a lookup of Table B which has the new multichoice column added to it. (Also Table B has a lookup of Table C in it)

Based on the values selected in the multiple-choice field’s combo box we will filter the gallery.

The syntax to bind the multichoice column to the combo box.

Choices(Table[@choicecolumn])

First, for the Items property of the Main Gallery, we have added the new column ColorChoices to Table A using the AddColumns and the Lookup function.

Then filtered based on selected items of the combo color choices, using the new ColorChoices column added.

ChoiceColumn[@Value] in comboBox.SelectedItems

We have also used the newly added ColorChoices column to bind it to the gallery inside the main gallery as it would have multiple values.

The result –

How to – Filter Collection / Items in Gallery based on the related (Lookup) record’s value – Power Apps / Canvas Apps (Dataverse/Dynamics 365)

Suppose we have 3 tables, Table A, Table B, and Table C related to each other as

Table A (n-1) Table B (n-1) Table C i.e.

Table A has a lookup of Table B and Table B has a lookup of Table C.

Below is our sample canvas app that has a gallery and a combo box.

What we would want is based on the Table C record’s name selected in the combo box, we want to filter the collection to only show those records that are related to it.

One of the ways we could implement this is by using the AddColumns to add Table C data to Table A and apply the Filter to it.

Below is the formula to achieve the same.

In Table A, add a column name “TableCName”.

To get the Table C name, perform a Lookup on Table B, where Table B GUID is equal to Table A’s Table B lookup field, and then fetch the Table C Lookup’s name from Table B.

And lastly, perform a Filter on this new column TableCName, based on the selected value in the combo box.
