Hello,

I am building a PowerApps form and have created a multi-select checkbox using a Gallery based on the instructions in this video. Create Multi select Checkboxes in Power Apps for SharePoint List Forms | Radio, List Box control (youtube.com) at 9:43.

There is a text field below the checkboxes and if 'Other' is selected, the text field is required. This works fine.

I would like to do the reverse, if the text field is not blank, then auto-select the 'Other' checkbox but am not finding a solution.

Any help would be appreciated. Below is a screen shot to help show the setup.

Thank you for the suggestions. The problem with the default as suggested for Checkbox8, is the checkbox isn’t only just for the Other option. The Gallery displays the choices and a variable is used to update the field in the SharePoint list.

Below are the property values for the Academic Staff_DataCard1, Gallery8, Checkbox8 and the text field AcadOther_DataCard1.

Gallery8 ITEM property pulls the choices from the SharePoint list datasource.
Checkbox8 TEXT property = ThisItem.Value
Checkbox8 DEFAULT property = ThisItem in academicstaffcombobox.SelectedItems
Academicstaffcombobox VISIBLE property = false
Academic Staff_DataCard1 UPDATE property = Coalesce(varAcadStaff,ThisItem.'Academic Staff')
For the text field, AcadOther_DataCard1, the REQUIRED property = If("Other (complete text box below)"in varAcadStaff.Value, true, false)

Thank you

HI,

in your Other CHeckbox default

If(!IsBlank(MyTextBox.Text), true, false)

So this will check the box the second the textbox has something in it.

please mark as the answer if this helps you.
