The SetFocus function in PowerApps is used to programmatically set the input focus to a specified control. This can be particularly useful for enhancing the user experience by guiding them through a form or ensuring that the appropriate control is selected for input.
PowerApps – SetFocus() function Syntax
- Control: The control to which you want to set the focus. This can be an input control such as a text input, dropdown, or button.
Notes:
- Control Types: SetFocus works primarily with input controls such as text inputs, dropdowns, and buttons.
- Timing: Ensure that SetFocus is used at appropriate times, such as after user actions or during form validation, to avoid setting focus unexpectedly.
PowerApps – Set Focus to a Text Input Control
Suppose you have a text input control named TextInput1 and you want to set the focus to it when a button is clicked:
You can place this in the OnSelect property of a button.
PowerApps – Set Focus on a control based on a Condition
You can set the focus based on certain conditions. For example, setting focus to a text input control only if a certain condition is met:
If(
IsBlank(TextInput1.Text),
SetFocus(TextInput1)
)
This sets the focus to TextInput1 if it is empty.
PowerApps - Chaining Focus between Controls
If you want to move focus from one control to another based on user actions, such as pressing Enter in a text input:
// On the OnSelect or OnChange property of the first text input
SetFocus(TextInput2)
