Hello the Community,

I would like get the last user selection of a combobox.

For example, in my Combobox, I have 3 items ["item1", "item2", "item3].
Firstly, the user selects "item1" and after "item2". Now, here I want display in a TextBox : "Your last selection is item1" (with a variable for example)

It works with a Dropdown and its onSelect property, but I need features of Combobox (mostly isSearchable and reset). So I can not use a Dropdown.

Could you help me ?

Bye.

Charlie.

Re: Get last selection with ComboBox

I'm using the ComboBoxSample data that is structured like the image below. You'll need to adapt the code to fit the Items in your ComboBox.

In the OnChange property of your ComboBox, enter:

Collect(boxHistory, {value: Self.Selected, index: Last(boxHistory).index + 1})

In your label/textbox, enter this for the Text property, where "Value1" is the field you want to display from the ComboBox.

LookUp(boxHistory, index = Last(boxHistory).index - 1).value.Value1

Result:

Be sure to clear the collection at the appropriate time so it doesn't retain the history past where you want it to.

Re: Get last selection with ComboBox

Hello,

Unfortunately, this update the lastSelected variable with the new value of my ComboBox, so like Set(lastSelected, Self.Selected.<Value>)

Re: Get last selection with ComboBox

In the OnChange of ComboBox, try UpdateContext({lastSelected: Self.Selected.<Value>}), where <Value> is the item value you want to capture. Then your label/textbox could be "Your last selection is " & lastSelected.
