Posted on by MiracleMan

I have a gallery that show different alternatives for the user to select one. These options comes from another table. I would like to make the checkbox in a way that user can only select one. None of the methods I saw worked for me. Any suggestions?

Hi @MiracleMan

It sounds like you want a Radio control. ref. https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/controls/control-radio

Can it be done with a Radio control? I tried but I wasnt able to figure out how the assign the field to the radio.

Also, I did the radio thing (living the default text) and it allowed me to click all of them.

You would do it similar to how you use a dropdown control, either hard code the choices like ["Choice1", "Choice2", etc] or you can use Distinct(yourdatasource, yourselectedcolumn) as the Items property. If you are using it to display choices in a Gallery, set the Default property of the Radio control to the Item as

LookUp(yourdatasource, ID = ThisItem.ID, yourselectedcolumn)

Hi @MiracleMan ,

You can achieve the single checkbox by a Gallery.

First, add a nested gallery2 inside the gallery1, set the Gallery2.Items to another table you mentioned. Then add a checkbox into gallery2, set Text property to ThisItem.ColumnName.

Next, configure the single-check function. Since the gallery can only be single-selected, set Checkbox.Default property: ThisItem.IsSelected, when the gallery item is selected, the checkbox is also checked.

However, It was found in the test that there were some conflicts between checkbox and Gallery Item, it didn't work as expected.

The workaround is here: Add a Blank Label into Gallery2, to be front of the checkbox, And set the Visible property: !ThisItem.IsSelected || !Checkbox1.Value. Use Label to avoid the selection conflict between the checkbox and Gallery Item.

Here we go.

Hope this helps.
