Limit combobox to items only

I would like to use the combo-box as a search and select for existing items . Currently I can type whatever in the combobox, but would like the text

I've tried a simple Reset(ComboBox) in the OnChange as a start, but it doesn't trigger when I enter anything in the field, only when I select an item in the list with the arrow.

I'd like something like the following:

If Not(ComboBox.Text in ComboBox.Items);Reset(ComboBox);

Unfortunately, you request is not possible because OnChange only triggers when something is selected. Selected values can be found the the Selected.Value property. Any "unselected" text found in the SearchText property.

My suggested workaround would be to put this code in the OnSelect property of the field that comes right after the ComboBox instead. It will basically do what you want.

If(IsBlank(DataCardValue4.Selected.Value)=true,Reset(DataCardValue4))

@agneumThe text you entered in Combo box is a search text, it doesn't change the combo box selection, so the OnChange property won't work.
What's more, we are not able to configure the SearchText property, so I am afraid your requirement cannot be done in PowerApps.
