How to enable and disable a field dynamically

Posted on by FedericoCoppola

Hi all,
I need to create a custom form to insert data in a SharePoint list, instead of using default input of SharePoint.

I need to use PowerApps due to I want that some input elements will be "dynamic".

In my case I have a combo box that gets data from SP List.

Is it possible to make the time field unusable if you choose items from the combo box?

For example:

option 1 -> choice of time possible

option 2 -> time selection not possible

How to identify the user's choice through the combo-box menu?
How can I use this choice to make the time field dynamic?

For me it is sufficient that hour field will be greyd out so it is not usable.
I have configured default value for this item to permit right input inside SharePoint List.

Thanks so much
Federico

Hi @FedericoCoppola ,
Set the DisplayMode property of hour combobox to:
If (RequestTypeComboBox.Selected.Value="Option1",DisplayMode.Edit,DisplayMode.Disabled)

Sure thing. You can set the Visible property of the dropdown control (and any other controls in that datacard) that you want to be gone based on a formula.

So, for example, if Request Type "X" and "Z" allow times, then set the visible property formula to the following:

yourRequestTypeControl.Selected.Value in "X|Z"

This will evaluate to true and thus the Visible property will be true and the control visible.

This assumes a "Value" based Items property on yourRequestTypeConrol. If not Value, then replace value with the correct column that is in the request type dropdown.

If you have other controls you want to be visible or not based on this, I would only use the formula once in, let's say, your HourDropdown control. Then for other controls, set their visible property to yourHourDropdownControlName.Visible

I hope this is helpful for you.

Thanks!
In my case, there are multiple options that allow time field.

How can I set multiple value?
Can I use multiple if case?

Thanks!
