Show A DropDown In PowerApps Containing Only Remaining Months In The Year

Within your Power Apps, you want to have a DropDown control which will show only the remaining months of the year.

For example, if you are opening the Power App in September DropDown control will show you months from September to December only.

We can achieve this in three steps as below:

  1. Create a collection which contains all months as text
  2. Create another collection, which appends month-number to each month
  3. Add a DropDown control and Filter collection from step 2 to show only months where month-number is greater than or equal to current month number
1 - Create a collection of all months
This can be done by adding formula below at App OnStart:

Collect(
    colMonths,
    Calendar.MonthsLong()
);

This will give a collection of 12 rows, one for each month: January, February, …, December

2 - Append Month-Number to this collection
This can be done by adding formula below just after the step 1

ForAll(
    colMonths,
    Collect(
        colNumberedMonths,
        Last(
            FirstN(
                AddColumns(
                    colMonths,
                    "MonthNumber",
                    CountRows(colNumberedMonths) + 1
                ),
                CountRows(colNumberedMonths) + 1
            )
        )
    )
)

The output from this step would look like:


3 - Item property of DropDown control
At this stage, we need to include months where month-number is greater than or equal to the current month. This can be done by updating Items property of the DropDown control to:

Filter(
    colNumberedMonths,
    MonthNumber >= Month(Today())
)

Generate QR code within Power Automate

Image
In this post we will learn how to dynamically generate QR code using Power Automate and then send that as a PDF attachment to an email address. For this post we will use Google Charts API, however note that since this is an external API so you need to check with your organizational data loss prevention policies, data security policies before making any API calls. Additionally, since this is a third-party API, this may be discontinued in the future and hence you may want to plan for this. The URL to generate a QR code looks as below: https://chart.googleapis.com/chart?cht=qr&chs= 300x300 &chl= powerplatformguide.blogspot.com Here we dynamically specify the dimensions of the QR code and its content based on our requirement. To build such a Flow, we will follow the following steps: 1 - Create an Instant Flow with three user input parameters as below: 2 - Add an action using OneDrive connector to upload a file from URL with parameters as seen below. We need to make sure that the de

Restrict Attachment control in PowerApps to accept Excel files only

Image
In one of the previous posts, we learnt how we can create a notification from Power Automate when a certain file-type is uploaded to a SharePoint Document Library. In this post, we will learn how we can restrict Power Apps attachment control to accept only a certain file-type. We will use Excel file (.xlsx) as the accepted file-type, however this can be similarly customized to any file-type(s). In the Attachment control, go the property  OnAddFile  and enter the following code: UpdateContext(     {         validFileType: EndsWith(             Lower(Last( AttachmentControl .Attachments).Name),             "xlsx"         )     } ) Now, the context variable that we have created, i.e.  validFileType  can be used to provide error message to the user, such as disabling the submit button or if using in-built Form, then putting in the errorMessage datacard. Updating error message datacard: Coalesce(     Parent.Error,     If(         !IsBlank(DataCardValue4.Attachments) && !va

Get start and last date of month using Power Apps

Image
In a previous post, we looked at how to get first date and last date of a month using expressions in Power Automate.  In this post, we are going to look at how we can get the same information in Power Apps. Here, we have used Today() to get the dates based on current date, however it can be made even more dynamic by using DatePicker and replacing Today() with DatePicker1.SelectedDate All dates calculated in this post are in the US format: MM-DD-YYYY First Day of Month DateValue(Month(Today()) & "/" & "1" & "/" & Year(Today())) First Day of Next Month In this step, we add 1 month to the first day of the current month DateAdd(     DateValue (Month(Today()) & "/" & "1" & "/" & Year(Today())),     1,     Months ) Last Day of Month In this step, we subtract 1 day from the first day of the next month DateAdd(     DateAdd(         DateValue (Month(Today()) & "/" & "1" &a
