Mat Autocomplete Selected Event

Now it s possible to recognize when the item is selected or deselected.

Mat autocomplete selected event.

The autocomplete is a functionality which shows the recommended options to the user when the user clicks on the input field or enters some keywords in an input field. Angular material select provides selectionchange event that emits when the selected value has been changed by the user. One with isuserinput true and one with false. If i have a selected value and change the value the onselectionchange will fire two events.

This allfruits val map user user username. The event selectionchange is used with mat select element as following. Both will fire soap request and the last soap request is the previous selected value isuserinput false. Today we are going to create autocomplete in angular 8 9 10 using angular material 10 ui components.

If yes then it is being sel. The onselectionchange event replaced the selected event. In autocomplete i want to display the username but i want to save the value of that chosen user id. On blur of the input validate function is called to check if the user wrote a valid value without selecting it in the list.

However after a selection has been made the selected item is the only item available in the autocomplete drop down no matter what changes i make. Now it s possible to recognize when the item is selected or deselected. After selection from drop down to show selected value a property of that object and not the complete object in text input we need to use displaywith property of mat autocomplete element to bind a function that will return display value for text input and we will bind complete object to mat option element so that we can get complete object. So even if i delete all the text in the input i still only see the previously selected option.
