Pass values to a button from function - xamarin.forms

Question

I have a function which is receiving parameters from another function and I have to pass these parameters to a button when it's execution get's complete !
async void CallCompanyApi(String CompanyGp, string CompanyId)
{
First.IsVisible = false;
Second.IsVisible = true;
// Next_Clicked(CompanyGp,CompanyId)
}
private void Next_Clicked(object sender, EventArgs e)
{
}
I have to pass these 2 parameters to that button !

Answer 1

you need to create class level variables to store these values
string _CompanyGp;
string _CompanyId;
async void CallCompanyApi(String CompanyGp, string CompanyId)
{
First.IsVisible = false;
Second.IsVisible = true;
// store the parameters in the class level variables
_CompanyGp = CompanyGp;
_CompanyId = CompanyId;
}
private void Next_Clicked(object sender, EventArgs e)
{
// you can now just reference _CompanyGp and _CompanyId
}
FYI, this is basic C# and really has nothing specific to do with Xamarin

Answer 2

Welcome to SO!
If CallCompanyApi and Next_Clicked located in different class, you can store them in Xamarin Forms by using Preferences.
using Xamarin.Essentials;
async void CallCompanyApi(String CompanyGp, string CompanyId)
{
First.IsVisible = false;
Second.IsVisible = true;
//Next_Clicked(CompanyGp,CompanyId)
Preferences.Set("CompanyGp", CompanyGp);
Preferences.Set("CompanyId", CompanyId);
}
Then in another class, click button will get them:
private void Next_Clicked(object sender, EventArgs e)
{
var CompanyGp = Preferences.Get("CompanyGp", "default_value");
var CompanyId = Preferences.Get("CompanyId", "default_value");
}
Else if they are in the same class, you can use the way as Jason's said.
============================Update=========================
You can set a default value if needed, such as follow:
var CompanyGp = Preferences.Get("CompanyGp", "Company_A");
var CompanyId = Preferences.Get("CompanyId", "1");
Defalut CompanyGp is Company_A, and default CompanyId is 1.
