🔹 Customizing Control Properties (Color, Font, etc.) in Power Apps – A Complete Guide

📌 Introduction

Customizing control properties in Power Apps allows you to create visually appealing apps that align with your brand, theme, or user preferences. You can change the color, font, size, border, visibility, alignment, and other properties dynamically.

✅ Why Customize Controls?

🎨 Enhances UI/UX by making the app visually appealing.
🔄 Improves accessibility with high-contrast colors and readable fonts.
⚙️ Provides dynamic UI changes based on user input or conditions.

🔹 Step 1: Understanding Control Properties

Power Apps controls have different properties such as:

✅ Appearance Properties

Fill → Background color
Color → Text color
Font → Font family
FontSize → Text size

✅ Border Properties

BorderColor → Border color
BorderStyle → Solid, Dashed, Dotted
BorderThickness → Border width

✅ Visibility & Positioning

Visible → Show/Hide a control
X, Y → Position of the control
Width, Height → Control size

📌 You can modify these properties dynamically using formulas!

🔹 Step 2: Changing Background and Text Colors

✅ Change the Background Color of a Button
1️⃣ Select a Button → Set the Fill property:

RGBA(0, 122, 255, 1)  // Blue color

2️⃣ Change Color (Text color):

White

📌 Now, your button has a blue background with white text!

✅ Use Theme-Based Colors

Fill = Theme.PrimaryColor

📌 Automatically adjusts colors based on app themes!

✅ Change Color Based on User Interaction
1️⃣ Change Fill based on hover:

If(Button1.Hover, RGBA(255, 0, 0, 1), RGBA(0, 122, 255, 1))

📌 Button turns red when hovered!

🔹 Step 3: Customizing Fonts and Text Size

✅ Change the Font Style of a Label
1️⃣ Select a Label → Set Font:

Font.'Segoe UI'

2️⃣ Change FontSize:

📌 Larger and more readable text!

✅ Make Text Bold, Italic, or Underlined

Bold: true
Italic: true
Underline: true

Example:

Label1.FontWeight = FontWeight.Bold

📌 Makes text bold dynamically!

✅ Change Font Based on User Role

If(User().Email = "admin@company.com", FontWeight.Bold, FontWeight.Normal)

📌 Admins see bold text, others see normal text!

🔹 Step 4: Modifying Border Styles

✅ Add a Border to a Text Input Field
1️⃣ Set BorderThickness:

2️⃣ Change BorderColor:

RGBA(0, 0, 255, 1)  // Blue border

✅ Change Border Style Dynamically

If(TextInput1.Text = "", BorderStyle.Dashed, BorderStyle.Solid)

📌 Dashed border if input is empty, solid if filled!

🔹 Step 5: Adjusting Control Visibility

✅ Hide a Control Based on a Condition

If(User().Email = "manager@company.com", true, false)

📌 Only managers can see the control!

✅ Show/Hide a Button Based on a Toggle

Button1.Visible = Toggle1.Value

📌 Toggle switch controls button visibility!

🔹 Step 6: Customizing Control Position & Size

✅ Change Position Dynamically

X = 100
Y = 50

📌 Moves control to specific coordinates!

✅ Resize a Control Dynamically

Width = Slider1.Value

📌 Slider adjusts the control’s width!

✅ Make Controls Responsive

Width = Parent.Width * 0.8
Height = Parent.Height * 0.5

📌 Control resizes based on screen size!

🔹 Step 7: Animating Controls for Better UX

✅ Fade-In Effect

1️⃣ Set Visible to false.
2️⃣ On OnSelect of a button, use:

UpdateContext({showLabel: true})

3️⃣ Set the Label.Visible property:

showLabel

📌 Label appears when the button is clicked!

✅ Change Color Gradually

If(Timer1.Value < 5, RGBA(0, 255, 0, 1), RGBA(255, 0, 0, 1))

📌 Color changes from green to red over time!

🔹 Step 8: Theming Your Power Apps for Consistency

✅ Use App Theme Colors

Fill = Theme.PrimaryColor
Color = Theme.TextColor

📌 Ensures uniformity across the app!

✅ Store Colors in Variables for Consistency

Set(AppPrimaryColor, RGBA(0, 122, 255, 1))
Button1.Fill = AppPrimaryColor

📌 Makes theme management easier!

🔹 Step 9: Implementing Conditional Formatting

✅ Change Background Based on Data

If(Dropdown1.Selected.Value = "Urgent", RGBA(255, 0, 0, 1), RGBA(0, 255, 0, 1))

📌 Red for urgent, green for normal!

✅ Highlight Rows in a Gallery

If(ThisItem.Status = "Pending", RGBA(255, 165, 0, 1), RGBA(255, 255, 255, 1))

📌 Pending items have an orange background!
