Add SearchText property to ComboBox

[MaciekWin3]

Is your feature request related to a problem? Please describe.

I am currently working on an app and I am using a ComboBox for one of the forms. I wanted the ComboBox to allow users to choose from a list, and if the item they want to choose is not present on the list, they can manually enter their desired option. After submitting the form, I noticed that the property "Text" of the ComboBox returns the text of the currently selected item, which is reasonable. However, I couldn't find an easy way to access the text that the user has typed in during their search.

Describe the solution you'd like

I am proposing the addition of a new field called "SearchText" that would return the current search text in the ComboBox.

Describe alternatives you've considered

I tried accessing Text for it but as I mentioned it currently returns currently selected item.
