Mat autocomplete selected event.

Bug feature request or proposal. Today we are going to create autocomplete in angular 8 9 10 using angular material 10 ui components. So even if i delete all the text in the input i still only see the previously selected option. Both will fire soap request and the last soap request is the previous selected value isuserinput false.

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. The event selectionchange is used with mat select element as following. In autocomplete i want to display the username but i want to save the value of that chosen user id. Now it s possible to recognize when the item is selected or deselected.

We ll create an angular app from scratch to show how. If i have a selected value and change the value the onselectionchange will fire two events. I am using an autocomplete mat autocomplete and at the moment it allows loading a list of users. 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. This allfruits val map user user username. Using mat autocomplete of material2. 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.
