I just want to know, whether the image is changed or not.

- The user opens the image with the Image-Editor.

- The user closes the Image-Editor. If the Image was changed, I want to save the image automatically

I have come across some strange behaviour of the RadSideDrawer component. On Android, everything works fine. On iOS however, the side drawer opens only when navigated to the containing page for the first time. when we have a button inside the drawer content and navigate through it to another page, then back to page where sidedrawer is positioned, the drawer content could not be open.

 If you open a datagrid's filter pop-up, navigate away from the page, then go back to the page, the filter pop-up will still be open.

If you attempt to close it, by way of the "X", the app will crash. In debug mode, a null reference error will occur. If navigating away from the grid with the filter closed, no crash will happen.

I want to be able to layer images over top of each other. Having a top layer that cannot move and contains a transparency. The bottom layer would contains  some kind of graphic and then crop it to the top layer.

The documentation notes that the TreeView should have its items default as IsExpanded=False, however, everything is expanded when I start my TreeView. This also includes the situation when I have a TreeView with a custom template (provided by the excellent people at Telerik, for dealing with cutoff expander icon issue!) and if I try to set Expanded explicitly to False via the template and viewmodel.

This seems to be pretty basic and I have to wonder if I'm not doing something correctly.

Thanks.

The BorderLocation property of ListViewItemStyle seems to either not be working correctly, or is severely limited in its capabilities.  Although the Location enum is not marked with [Flags], the values 0, 1, 2, 4, 8, 15 seem to imply bit flags that should be able to get OR'd together. However, when trying to use Location.Top | Location.Bottom, the result is NO border at all.

 

Example:

    public class BorderLocationExample : ContentPage
    {
        private readonly ListViewItemStyle BorderAll = new ListViewItemStyle
        {
            BorderColor = Color.Blue,
            BorderLocation = Location.All,
            BorderWidth = 8
        };

        private readonly ListViewItemStyle BorderTop = new ListViewItemStyle
        {
            BorderColor = Color.Blue,
            BorderLocation = Location.Top,
            BorderWidth = 8
        };

        private readonly ListViewItemStyle BorderTopAndBottom = new ListViewItemStyle
        {
            BorderColor = Color.Blue,
            BorderLocation = Location.Top | Location.Bottom, // <-- DOESN'T WORK !!!  These items have NO border at all.
            BorderWidth = 8
        };

        public BorderLocationExample()
        {
            BackgroundColor = Color.Gray;

            var items = new ObservableCollection<string>
            {
                "Item 1",
                "Item 2",
                "Item 3",
            };

            Content = new StackLayout
            {
                Orientation = StackOrientation.Vertical,
                Children =
                {
                    new RadListView
                    {
                        ItemsSource = items,
                        ItemStyle = BorderAll
                    },
                    new RadListView
                    {
                        ItemsSource = items,
                        ItemStyle = BorderTop
                    },
                    new RadListView
                    {
                        ItemsSource = items,
                        ItemStyle = BorderTopAndBottom
                    },
                }
            };
        }
    }

When using the __ItemStyle properties of RadListView, they are not being applied if the SelectionMode is set to None. It makes sense that the PressedItemStyle and SelectedItemStyle properties are not used, since they are not applicable if nothing can be selected. However, the ReorderItemStyle in particular should still be used.

 

Example:

    public class ItemStyleNotAppliedExample : ContentPage
    {
        private readonly ListViewItemStyle WhiteBG = new ListViewItemStyle
        {
            BackgroundColor = Color.White
        };

        private readonly ListViewItemStyle YellowBG = new ListViewItemStyle
        {
            BackgroundColor = Color.Yellow
        };

        private readonly ListViewItemStyle RedBG = new ListViewItemStyle
        {
            BackgroundColor = Color.Red
        };

        private readonly ListViewItemStyle BlueBG = new ListViewItemStyle
        {
            BackgroundColor = Color.Blue
        };

        public ItemStyleNotAppliedExample()
        {
            BackgroundColor = Color.Gray;

            var items = new ObservableCollection<Item>
            {
                new Item("Item 1"),
                new Item("Item 2"),
                new Item("Item 3"),
                new Item("Item 4"),
                new Item("Item 5"),
            };

            Content = new RadListView
            {
                SelectionMode = SelectionMode.None,
                IsItemsReorderEnabled = true,
                ItemsSource = items,
                ItemTemplate = new DataTemplate(typeof(ItemView)),

                ItemStyle = WhiteBG,
                PressedItemStyle = YellowBG,
                SelectedItemStyle = RedBG,
                ReorderItemStyle = BlueBG,
            };
        }

        private class Item
        {
            public string Name { get; }

            public Item(string name)
            {
                Name = name;
            }
        }

        private class ItemView : ListViewTemplateCell
        {
            public ItemView()
            {
                var checkbox = new CheckBox
                {
                    VerticalOptions = LayoutOptions.Center
                };

                var label = new Label
                {
                    VerticalOptions = LayoutOptions.Center
                };

                label.SetBinding(Label.TextProperty, nameof(Item.Name));

                View = new StackLayout
                {
                    BackgroundColor = Color.Transparent,
                    Orientation = StackOrientation.Horizontal,
                    Children =
                    {
                        checkbox,
                        label
                    }
                };
            }
        }
    }

You can reproduce this by changing input language to any region that uses a comma decimal separator (e.g. Duetsch). The comma is ignored, ultimately corrupting the data

To reproduce:

Step 1 - File > New > LoadOnDemandCollection Demo

Follow the LoadOnDemandCollection documentation https://docs.telerik.com/devtools/xamarin/controls/datagrid/load_on_demand#loadondemandcollection

Step 2 - Deploy to UWP

=> Observe the DataGrid will be stuck in busy state after the initial set of items load

Hi,

Do you plan add to image editor perspective correction option?
I know it is image analysis, but it could be even manual possibility to select document corners and transform to square image.

Or maybe it is possible using some other control or functionality now?
