Hello ,

I am new at Xamarin Forms and this is what i am trying to do.

Based on the month i want to show a document from Google docs in a Webview

I know how to show the document but not the if statement.

Trying to put a label with the month showing in a stacklayout with the webview , so far so good.

The label is showing 11

But how do i make it work that when the month is changing it is going to another document.

This month is

Webview.Source = "https://docs.google.com/spreadsheets/d/1h2wQMlPpvnajq_Dg-Yx6Gwh4wzy7ZPd3Kp5gnDnEszY/edit?usp=sharing";

and this for December

https://docs.google.com/spreadsheets/d/1BEryoKhaTP6tx2VsYibYXE5kJoEBKqGFNrhov1W_b7s/edit?usp=sharing

The mainpage

Text="{Binding Source={x:Static sys:DateTime.Now}, StringFormat='{0:MM}'}" />

HorizontalOptions="FillAndExpand"

x:Name="progress"

ProgressColor="Maroon"

IsVisible="True"/>

HeightRequest="1000"

WidthRequest="1000"

Navigating="OnNavigating"

Navigated="OnNavigated"

VerticalOptions="FillAndExpand"/>

And the Main.xaml.cs

public partial class MainPage : ContentPage
{
public MainPage()
{
InitializeComponent();
Webview.Source = "https://docs.google.com/spreadsheets/d/1h2wQMlPpvnajq_Dg-Yx6Gwh4wzy7ZPd3Kp5gnDnEszY/edit?usp=sharing";
}
protected async override void OnAppearing()
{
base.OnAppearing();
await progress.ProgressTo(0.9, 900, Easing.SpringIn);
}
protected void OnNavigating(object sender, WebNavigatingEventArgs e)
{
// SfBusyIndicator busyIndicator = new SfBusyIndicator();
progress.IsVisible = true;
// busyindicator.IsVisible = true;
}
protected void OnNavigated(object sender, WebNavigatedEventArgs e)
{
// SfBusyIndicator busyIndicator = new SfBusyIndicator();
progress.IsVisible = false;
// busyindicator.IsVisible = false;
}
}
}

Ok, strange. You'd have to debug to the line, and see what's happening. I have no clue as to why the date would get the wrong month.

If debugging is not an option for whatever reason, add a label/textbox to your form where you can add some debug information manually from your code.

i put the app on my android phone and change the date , on my pc i can't change the date because it is from my company and they don't allow that

Change the date on phone to 12 month is working and 11 also but the rest not ?

Thanks for the reply pritaeas,

It seams to work , only when i put the date on Oktober or September nothing is happening

Maybe it was the 9 and not 09 but no luck the 10 is also not oke , the 11 en 12 are working.

The links to de documents are good because is switch them

This is what i have now , did not try the rest of the months

I am from holland but month 11 is month 11 , the date is set to 18-11-2019 in the phone.

When change the date to 18-10-2019 then nothing , 18-12-2019 is working
public MainPage()
{
InitializeComponent();
Webview.Source= monthlySources[DateTime.Now.Month];
}
private readonly Dictionary monthlySources = new Dictionary()
{
{ 01, "" },
{ 02, "" },
{ 03, "" },
{ 04, "" },
{ 05, "" },
{ 06, "" },
{ 07, "" },
{ 08, "" },
{ 09, "https://docs.google.com/spreadsheets/d/1sHKgIxZ3ut0Dd-6fEt1Ynk84sOhyLC1Q1RX8SW3QtS4/edit?usp=sharing" },
{ 10, "https://docs.google.com/spreadsheets/d/1ldcZ6WXXMI73xXaGw1Nxa2LDTVydkRiYzMRs1nYzE84/edit?usp=sharing" },
{ 11, "https://docs.google.com/spreadsheets/d/1h2wQMlPpvnajq_Dg-Yx6Gwh4wzy7ZPd3Kp5gnDnEszY/edit?usp=sharing" },
{ 12, "https://docs.google.com/spreadsheets/d/1BEryoKhaTP6tx2VsYibYXE5kJoEBKqGFNrhov1W_b7s/edit?usp=sharing" },
};

Use a dictionary:

private readonly Dictionary monthlySources = new Dictionary()
{
{ 1, "" },
{ 2, "" },
{ 3, "" },
{ 4, "" },
{ 5, "" },
{ 6, "" },
{ 7, "" },
{ 8, "" },
{ 9, "" },
{ 10, "" },
{ 11, "https://docs.google.com/spreadsheets/d/1h2wQMlPpvnajq_Dg-Yx6Gwh4wzy7ZPd3Kp5gnDnEszY/edit?usp=sharing" },
{ 12, "https://docs.google.com/spreadsheets/d/1BEryoKhaTP6tx2VsYibYXE5kJoEBKqGFNrhov1W_b7s/edit?usp=sharing " },
};

Then you can use:

string source = monthlySources[DateTime.Now.Month];
