I put layout.width into OnAppearing method of MainPage, the width will always be -1 and it won't be updated until it changed once. And its value won't be zero, I can't reproduce your issue. Would you mind sharing more code snippets?
In addition, you can try using the ViewRenderer in MAUI and get the real width of native control in OnElementPropertyChanged method.

Hi Wenyan Zhang and thank you

This is my code but I don't want to use DeviceDisplay to get the layout width

So I used verticalLayoutWidth = (int)vLayout.Width but that not work

private void MainPage_Loaded(object sender, EventArgs e)
{
verticalLayoutWidth = (int)vLayout.Width;

screenDensity = DeviceDisplay.Current.MainDisplayInfo.Density; screenWidth = DeviceDisplay.Current.MainDisplayInfo.Width; vLayoutMargin = (int)vLayout.Margin.HorizontalThickness; InputTB.WidthRequest = (screenWidth / screenDensity) - vLayoutMargin; OutputTB.WidthRequest = (screenWidth / screenDensity) - vLayoutMargin;

}

Thank you very much

Hi @Haviv Elbsz , May I ask what version and platform you are using? Why are you trying to get the width? What do you plan to do with it? You want to get the width of a VerticalStackLayout, right? Are you trying to get the Width before everything's been laid out?

Hello,

You could try to use Grid, then set three columns(1,8,1), and add the Button on second coumn.

<Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="8*" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions>

Best Regards,
