This is the correct answer, why all the downvotes. One note, the value needs to be set in the constructor of the component.

Deprecated warning. Maybe add that the defualt value can be set with the Validators when using FormControl? Like so: this. For a template driven form, I did this and got default selection.

Seems it is working fine stackblitz. If you have the array of objects with isSelected key, I think it will work. Will have to try whenever I hop onto my workstation in the morning. Will update here.

You can get a copy here. The book is updated to Angular 8. In this app, there is an angular component fetchdata. The API response is shown in a tabular format. We can easily fix this by adding a datePipe. First, we need to expose an API which returns the weather forecasts list. Next is the updated code of fetchdata. There is also a method defined filterForeCasts which gets called on change event of the dropdown. This method filters the forecasts list based on the selected value and then returns the result.

Highlighted code in the below snippets is the newly added code to the fetchdata.

Multiselect dropdown in angular with search filter

Lastly, put this HTML in fetchdata. As you can see here, the filterForeCasts method is called on the dropdown change event to filter the weather forecasts based on the selected value. Run the application and navigate to fetch data. You should see a dropdown having a list of weather summary.

Changing the selection will also update the weather forecast grid. If you really want to master Angular 8, ng-book is the single-best resource out there.

In Angular 2 how can I get the selected text from an option. Also since I have a dynamic number of selecs? I think I need to add to an array t how Can I get the text for all. I was able to get the value but what I need is the text.

So first, change the type of your selected property inside your component to an array of any and initialize it. You are probably looking for ngValuewhich binds the whole object, but with that, add ngModel in the mix, but that means you have another variable. Maybe there is a better way to solve this, without an extra variable. If so, please do tell! The error you are getting is because you need to import FormsModule to your NgModule.

I notice that what you're displaying inside the option element is controlList. Value but what's bound to [value] is just controlList. Another thing you could do is declare a getter and setter for selected. Value" it works, however, All the other dropdowns lose the selection. Value ; basically printing out selected prints the object.

You can do: JSON. This works, but it's a bit of a workaround Well, that was essential information, of course this solution won't work then Please provide a plunker with static data, this was more complicated than thought, and would be easier to solve by having a plunker to play with!

In this case, it appears that selectedValue would be a number -- the id of the selected item. However, I'd actually like to bind to the country object itself so that selectedValue is the object rather than just the id. I tried changing the value of the option like so:. It seems to place an object in my selectedValue -- but not the object that I'm expecting.

You can see this in my Plunker example. I also tried binding to the change event so that I could set the object myself based on the selected id; however, it appears that the change event fires before the bound ngModel is updated -- meaning I don't have access to the newly selected value at that point.

StackBlitz example. If the value is an object, the preselected instance needs to be identical with one of the values. Check the working example here. Also, if nothing else from given solutions doesn't work, check if you imported "FormsModule" inside of "AppModule", that was a key for me. You can get selected value also with help of click by passing the selected value through the function.

If entering the page with model already set the dropdown is not set accordingly Strinder a frequent mistake is to use another object instance for selectedValue than for c of the default item.

A different object even with the same properties and values doesn't work, it has to be the same object instance.

The following code works as it should and sets the default value when I do not use the [formControl] binding. However when I use the form control binding it fails to set the default option on the mat-select component.

Bind Select DropDown List in Angular 8

I searched stack overflow and came across this solution which works however I get a warning in the browsers console, I'm not sure if this is the correct method of achieving this. It looks like you're using ngModel on the same form field as formControl.

Support for using the ngModel input property and ngModelChange event with reactive form directives has been deprecated in Angular v6 and will be removed in Angular v7. Any help to clarify or enlighten me on the correct method of achieving this would be greatly appreciated.

The console warning tells you exactly what the issue is, either use the ngModel directive or the formControl directive, not both. Check this question on how to select a default option with a formControl it is for a multi select, but it works the same for your case. And in your component you can set the value of your FormControli. You can set the value of the control when you build the form to the current year, in that way Angular will retrieve the value on form control binding.
