Xamarin Forms - retrieve value of dynamically added entry control value on button click - xamarin

Question

I want to get all entry controls value on button click.
My code is as below - this is how I am adding dynamic control on page:
public BookSeat()
{
ScrollView scroll = new ScrollView();
StackLayout stack = new StackLayout();
int count = Convert.ToInt32(Application.Current.Properties["NoPersonEntry"]);
for (int i = 0; i < count; i++)
{
stack.Children.Add(
new StackLayout()
{
Children = {
new Label (){TextColor = Color.Blue, Text = "First Name: ", WidthRequest = 100,StyleId="FnameLabel"+i },
new Entry() {StyleId="FnameEntry"+i }
}
}
);
}
Button button = new Button
{
Text = "Save"
};
button.Clicked += OnButtonClicked;
stack.Children.Add(button);
scroll.Content = stack;
this.Content = scroll;
}
And below code is for I want to get value on button click
public void OnButtonClicked(object sender, EventArgs e)
{
// Here I want to get value
}

What you can do is to store your entries in a list so that you can access them later on.
For example :
private List<Entry> _myentries = new List<Entry>();
public BookSeat()
{
ScrollView scroll = new ScrollView();
StackLayout stack = new StackLayout();
int count = Convert.ToInt32(Application.Current.Properties["NoPersonEntry"]);
for (int i = 0; i < count; i++)
{
var entry = new Entry() {StyleId="FnameEntry"+i };
_myentries.Add(entry);
stack.Children.Add(
new StackLayout()
{
Children = {
new Label (){TextColor = Color.Blue, Text = "First Name: ", WidthRequest = 100,StyleId="FnameLabel"+i },
entry
}
}
);
}
[...]
}
Now you can do this :
public void OnButtonClicked(object sender, EventArgs e)
{
foreach(var entry in _myentries)
{
var text = entry.Text;//here we go
}
}
