To restrict the selection of future date and time in a Canvas app and display an error message while disabling the submit button, you can use a combination of controls, formulas, and properties. Here's a step-by-step guide on how to achieve this:
Create a Date Picker control and a Time Picker control in your Canvas app. Let's assume you have named them DatePicker1 and TimePicker1, respectively.
Add a Label control to display the error message. Let's name it ErrorMsgLabel.
Set the OnChange property of the DatePicker to a formula that checks if the selected date and time are in the future and displays the error message accordingly. If the date and time are valid, you can perform the desired submit action. Here's an example formula:
If(
DateTimeValue(Text(DatePicker1.SelectedDate & " " & TimePicker1.SelectedTime)) > Now(),
UpdateContext({ ShowError: true }),
SubmitForm(Form1)
)
In this formula, Form1 represents the form you want to submit.
- Set the Text property of the ErrorMsgLabel to the error message you want to display. You can use a variable to store the dynamic error message. Here's an example:
If(ShowError, "Invalid date and time selected.", "")
- Finally, set the DisplayMode property of the DropDown to disable it when the error message is displayed:
If(ShowError,DisplayMode.Disable,DisplayMode.Edit)
That's it! Now, when the user selects a future date and time, the error message will be displayed, and the submit button will be disabled. Adjust the formulas and error message text to fit your specific requirements.
