Hi:

Would be possible to display the calendar filling the whole Android screen.  Then switch the display mode to Week, but changing the default row height.

I tried it in Android, without luck.  In iOS, the following statement works, but not in Android:

calendar.HeightRequest = 110;

Thanks in advanced

When I try to use calendar to display Simple-Chinese, Traditional-Chinese, Korea... then it will cause JNI exception, please see attachments.

Is there any way to correct setting up calendar widget or it's not ready to support multi-language?

Thanks.

I've started to use RadListView for my app.

My use case looks more or less:
- User has a ListView

- User can tap on any Item of ListView

- Some business logic is done at given Item

- User can tap again on any Item of ListView (even if it has been tapped just before)

For OOTB Xamarin.Forms ListView, I've just use command, binded to *SelectedItem* property of ListView, and after did some business logic, I've just pass *null* as SelectedItem (it informs ListView, that there is still no selection):

public MyItemObject SelectedItem
{
    get
    {
        return _selectedItem;
    }
    set
    {
        if (_selectedItem != value)
        {
            _selectedItem = value;
 
            // Some business logic here
 
            // Deselect item from ListView
            _selectedItem = null;
            RaisePropertyChanged();
        }
    }
}


However for *RadListView* it not working properly - it doesn't matter, if I use such "hacky" logic as for *ListView* or not, I had to tap 2 times, after my initial tap, so:
- User taps at item no. 1 - some logic is performed (OK)

- User taps again at item no. 1 - nothing is done, except "deselecting" *RadListView* selection (KO)

- User taps againt at item no. 1 - some logic is performed (OK)

Is there any possibility, to deselect *RadListView* from code behind?

Thanks a lot!

Hello, I have a Xamarin.Forms with C# application that I am developing. 
At the moment the user can log in and authenticate using Azure AD. 
They are then taken to a XAML tabbed page that uses a ‘Telerik’ calendar control. 
I need to bind the event data from office365 into this control. 
I also have 2 list views that need to bind data from Office365 through the API. 
These will be listed as tasks and contacts. 
The user should be able to add, edit and delete said contacts/tasks. 
Can anyone assist with this?
Thanks

Hello, 

I'm trying to call http://lotmaker.dumouchelles.com:8082/api/AuctionMobile

and receive json via data source and show it in tableView or ListView.

am trying something like 

 

base.ViewDidLoad();

            UITableView tableView = new UITableView(this.View.Bounds);

            this.View.AddSubview(tableView);
            //string url = "http://api.myjson.com/bins/3kj37";
            string url = "http://lotmaker.dumouchelles.com:8082/api/AuctionMobile";

            dataSource.LoadDataFromURL(url, TKDataSourceDataFormat.JSON, "AuctionMobile", (NSError err) =>
            {
                if (err != null)
                {
                    Console.WriteLine("Can't connect with the server!");
                    return;
                }
                this.dataSource.DisplayKey = "LotNumber";
                tableView.DataSource = this.dataSource;
            });

 

Any thought why I'm not getting data ? 

 

Thanks

Is there any way to format the value labels in a RadCartesianChart BarSerie? Let's say I have a value in my VM as 10 but I wanna show 10.000.

In Xamarin I cannot find anything such as BarSeries.LabelDefinitions and BarSeries.ValueBinding has only one property called PropertyName.

 

Any thoughts?

I have noticed in the docs there is a guide on how to implement an autocomplete editor in android:

http://docs.telerik.com/devtools/xamarin/controls/dataform/howto/dataform-howto-use-native-editors-android#autocomplete-editor-in-android

Is there an equivalent example on how to do this in iOS as I am struggling to get it working?

Thanks, James.

I have a custom renderer for drawing a candlestick chart in Xamarin Forms.

I have this in the android side;

if (series.ItemsSource != null)
                        {
                            androidSeries.Data = new Java.Util.LinkedList(series.ItemsSource.OfType<object>().ToArray());
                        }

 

and the ItemsSource always shows as having a null value even though it is populated with 21 values.

 

any ideas on how to fix this ?

Hi Support:

We finished evaluating the Telerik UI controls for Xamarin Forms on Android and are now in the phase of evaluating the onthe iPhone. 

On Android, when the calendar viewmode is set to week, it shows the title and the day names properly. (please open the Android attachment).

However on the iPhone, the title and day names are not displayed.  Also the height of each day cell takes the whole vertical space, and we need to have the same height of the cell that is rendered on the Android (See iPhone attachment).

Please let us know how can we get the same look and feel on the iphone for these 3 things (cell height, title and day names).

Thanks

David
