No matter what... xamarin keep coming up with new roadblock and new error... Each day it's something new...
anyone with any ideas on what is going on fro the error below?

Please note...a week ago I was some how apply to get this application to run on the IOS simulator as one day I do hope I will play able to put this application on or dev store.. one day... but each new day brings new wacky errors... I have to ask... does xamarin work???

I know some will answer yes... but I just don't understand why when you follow the guides the thing does not work... I mean seriously,... how do you doploy your app if you can't get it to run on the sim... but a few days before... it ran on the sim?? What changed??

This app runs on the Android simulator just fine... Any help would be appreciated.Thanks!

There was an unhandled exception trying to deploy and run your application. \nSystem.Exception:
The OutputPath property is not set for project 'NameOfTheApplication.iOS.csproj'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='Debug' Platform='iPhone'. This error may also appear if some other project is trying to follow a project-to-project reference to this project, this project has been unloaded or is not included in the solution, and the referencing project does not build using the same or an equivalent Configuration or Platform.

Sorry if the question's a bit convoluted! This has me stumped at the moment: I have a ListView and I'm creating the DataTemplate programatically to be able to make it responsive. My ListView's ItemSource is a list called "Recipes" made up of "Recipe" objects.
How can I create a label in codebehind and bind its text property to, say, Recipe.Title? Here's my current code and what I'd like it to do:

                    private void GenerateTitleLabel(Grid grid)
                    {
                        Grid.SetColumn(grid, 1);
                        grid.Margin = 1;
                        grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(2, GridUnitType.Star) });
                        grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(4, GridUnitType.Star) });
                        grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(2, GridUnitType.Star) });
                        grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(2, GridUnitType.Star) });
                        Label title = new Label
                        {
                            Style = Application.Current.Resources["styleLabelTitle"] as Style,
                        };

                        //Here I'd set the binding to the Title attribute in my Recipe class
                        title.SetBinding(???);

                        Grid.SetRow(title, 1);
                    }

That's it. If anything's unclear, let me know!

Hi All,

So the question is about formatting I guess.

I have an application that looks great in Android... but look bad in apple Iphone.

For example I have a back ground image in apple and the images seems to duplicate. I guess it does that to fit the screen of the device?
Is there a way to not have the image to repeat or is there a way I can remove the image in the xamarin forms without it removing it for my android version?

Next question is the buttons...again In Android the buttons look like buttons.
In the apple Iphone the buttons look like blue text which makes it hard to see on the background image (which if I could remove from apple..I guess the text would be ok if the back ground was plain white.

Finally My Icon works great for Android... bit for apple there is not icon...when the application starts...its just some type of blank icon.

Again.. wish the apple application version looked as good as the android... but it it can't I am okay with. If I can strip out th dress up graphics from the apple version of the application that is fine. As I don't want to go through the hassle that Im sure it is to make this look nice for an apple device..

my main worry is messing up the Android out put.

Thanks All!

Hey guys,

I'm really frustrated and require some help from you. I'm not really new at Xamarin, but some things won't get in my brain. Maybe I haven't understood the entire logic so far.

But, my problem is: I've been adding a Button to the content page and all were working fine. So, I had to change the background color and now it's messed up! When I click the button, it shows WHILE the press event is invoked, a small visible rectangle with the 0.25 scale of the entire button on the top left of the button.

Can someone help me? I've made a screenshot WHILE PRESSING THE BUTTON here:

Note: BEFORE changing the background color, all has been working fine. AFTER setting the background color, the color gets changed well and is correct but the PRESS/CLICK/ACTIVE state of the button shows a small - unrequired - rectangle on the top left of the button.

Thankful for every answer.

Kind regards,
Dominik G.
