  • Select the “Visibility” property and insert the Power FX formula describing the functionality for dynamically hiding & displaying the button. In our scenario, we will hide our command button when the form’s field “SRL” is less than 2 and display the command button when the “form’s field “SRL” is more than 2. Below is the Power FX formula used for achieving this functionality.
  • Note: – Use the command “Self.Selected.Item” to target the currently opened record / row.
If(Self.Selected.Item.SRL < 2, false, true)
