tl;dr

Components are reusable building blocks in Power Apps which increase maker productivity and design consistency. If you are new to them, you should definitely start to learn how to build them - This post will make it easier for you! This progress bar component showcases also custom properties to give you an idea on how you can make a component customizable to different needs.

Progress Bar component: the result

Let’s dive in head first and have a look how the completed components will look like. As I designed them to be adjustable to different designs, here is some inspiration:

As you can see, the progress bars can have different widths and heights and can be horizontal or vertical. We will first tackle the horizontal one.

Build the component - horizontal

For this component, that I will name cmp_ProgressBar_hor, we only need two text labels, which you need to insert

• lbl_BarCurrent, which shows the progress
• lbl_barTotal, which shows the total

Create the custom properties

We will need a bunch of custom properties so the component is more flexible

• barMaxValue (Number), set default to 100 - its the maximum value of the progress bar
• barCurrentValue (Number), set the default gbl_barValue - this is the variable that controls how much progress is being made
• barMaxFill (Color), I set the default to ColorValue("#1e6091") - it’s the fill color of the maximum value
• barCurrentFill (Color), I set the default to ColorValue("#168aad") - it’s the fill color of the current value
• barWidth (Number), I set the default to 200, it’s the width of the progress bar
• barHeight (Number), I set the default to 42, its the height of the progress bar
• labelColor (Color), I set the default to White, it’s the color of the label that shows the percentage of progress

Set properties for the labels

For our lbl_BarCurrent:

• Color: cmp_ProgressBar_hor.labelColor
• Fill: cmp_ProgressBar_hor.barCurrentFill
• Height: lbl_barTotal.Height
• Text: RoundUp(100*(cmp_ProgressBar_hor.barCurrentValue/cmp_ProgressBar_hor.barMaxValue),0) & "%"
• Width: lbl_barTotal.Width*cmp_ProgressBar_hor.barCurrentValue/cmp_ProgressBar_hor.barMaxValue
• X: lbl_barTotal.X
• Y: lbl_barTotal.Y

For our lbl_barTotal:

• Fill: cmp_ProgressBar_hor.barMaxFill
• Height : cmp_ProgressBar_hor.barHeight
• Text: ""
• Width: cmp_ProgressBar_hor.barWidth
• X: 5
• Y: 5

Now set the Width of the component to cmp_ProgressBar_hor.barWidth+10 and the Height to cmp_ProgressBar_hor.barHeight+10.

If you want to try out the component in your app, you will need to have something that will set the value of our variable gbl_barValue. You can do this with a slider control. Set the OnChange property to Set(gbl_barValue, Self.Value), move the slider and voila, your bar is making progress! You can now insert another component instance and play around with the custom properties and change height and width, the label color as well as the fill colors.

Build the component - vertical

If you now want to create the same component but vertical, you can duplicate the component and then we only need to adjust a few things. Name your vertical component cmp_ProgressBar_vert.

For our lbl_BarCurrent:

• Color: cmp_ProgressBar_vert.labelColor
• Fill: cmp_ProgressBar_vert.barCurrentFill
• Height: lbl_barTotal.Height*cmp_ProgressBar_vert.barCurrentValue/cmp_ProgressBar_vert.barMaxValue
• Text: RoundUp(100*(cmp_ProgressBar_vert.barCurrentValue/cmp_ProgressBar_vert.barMaxValue),0) & "%"
• Width: lbl_barTotal.Width
• Y: lbl_barTotal.Y+lbl_barTotal.Height-Self.Height

For our lbl_barTotal:

• Fill: cmp_ProgressBar_vert.barMaxFill
• Height: cmp_ProgressBar_vert.barHeight
• Width: cmp_ProgressBar_vert.barWidth

How can we use this component in apps?

People like to know the answer to the question Are we there, yet?. Indicating their progress in long forms is a nice way to improve user experience and satisfaction, as people then know what to expect.
