Xamarin addind ToolbarItem in dynamically in C#

Question

I am new with Xamarin.

I am using Xamarin using font-awesome 4.7 version, I am trying to add a ToolbarItem in the code behind:

var toolBarItem = new ToolbarItem
{
    Icon = "&#xf053;",
}

In xaml file I can do something this:

<assets:Icon Text="&#xf053;" TextColor="#5DD046" FontSize="24" HorizontalOptions="Start" VerticalTextAlignment="Center" Margin="25,0,0,0"/>

But I need it to work in the code behind, can someone advise me how to go about it?

Since you were able to get it working in Xaml, I'm assuming you've already written renderer for changing the toolbar item font (to font-awesome). Just set the `Text` property of `ToolbarItem` to the unicode value of the icon (in this case `\uf053`). — memsranga, Nov 16 '18 at 07:22

From code behind you can do like this

Icon = "\uf053"

Or

Icon = ((char)0xf053).ToString();

Your original values is "", so for all values the same rule applies to change.

Thank you but how do you indicate that I want it to be an icon and NOT a text? – ML13 Nov 16 '18 at 13:44
We not need to know it. By the forms of string it is recognizing. Are you facing that conflict? – R15 Nov 16 '18 at 13:46
All I am getting is a marking for a icon (like a small square box with a x in the middle) but not the the actual font awesome icon I need – ML13 Nov 16 '18 at 14:19
I think you need to set `FontFamily`. For `Toolbar` you need to use custom renderer to do so, which would be more complicated. I'll suggest you here to use icons. for more information visit this https://stackoverflow.com/questions/52274361/xamarin-fontawesome-not-working-from-code-behind – R15 Nov 16 '18 at 14:40
If I do Text = ((char)0xf053).ToString(), at lest I get the square box mentioned above but if I do Icon = ((char)0xf270).ToString(), I get nothing – ML13 Nov 16 '18 at 15:14
@ML13 - I have updated my answer. Now I notice that it should have been `Icon` instead of `Text`. – R15 Nov 16 '18 at 16:11

You have created a toolbar item but in order to appear, it has to be added to the page. So in your page code you should call

this.ToolbarItems.Add(toolBarItem);

after creating the item.
