Introduce support for specifying the speed of the auto-scrolling functionality (when the IsAutoScrollingEnabled property is set to True).

Posibility to group the TileViewItems needed

When the IsSelectionEnabled and IsSynchronizedWithCurrentItem properties are set to True, an InvalidOperationException is thrown.

The UnselectAll method, which comes from MultiSelector, does not unselect all items when manually select them one by one. The method will unselect the items in the order they were selected, one by one.

In application with heavier styles and a slower machine when items are dragged and swiped it sometimes leads to exception:
Cannot animate the 'VerticalOffset' property on a 'Telerik.Windows.Controls.TileViewPanel' using a 'System.Windows.Media.Animation.DoubleAnimationUsingKeyFrames'

Hi guys,

I am investigating a weird scrolling behavior in our app, I have more or less reproduced it in the attached sample app. I say 'more or less' because the little sample doesn't exactly have the same structure as our app but the result looks to be the same as what is happening in our software.

When declaring an unnamed style that targets the RadTileViewItem, scrolling the minimized TileViewItems while have one in the Maximized state, reverts all the minimized ones to their 'Normal' state as well as the one that was maximized. If the RadTileViewItem style is given a Key in the resource dictionary and used explicitly in the TileView's ItemContainerStyle property the scrolling works fine.

Both ways of using the style should, in my opinion, behave exactly the same.

Please take a look.

Thanks.

 

Initial state of TileView:
A B C
D E F
G

G is moved between B and E (current result)
A B C
D G F
E

REQUESTED RESULT:
A B C
D G F
   E

TileView: Add different methods for arranging Tile items. Asked by a client.
For example "ColumnsOnly" would only shuffle items down within the column being inserted into. However this would also mean that gaps would have to be allowed. E.g.
A B C
D E F
G

If G moved between B and E then
A B C
D G F
   E

Reproduced with Implicit Styles with NoXAML binaries only. The workaround is to set a fixed value for the RestoredHeight property of RadTileViewItem

You can work this around by setting the PreservePositionWhenMaximized to False and implement custom preserving logic. You can see this approach in the attached project.

private bool isManualPositionChanged = false;
private Dictionary<RadTileViewItem, int> maximizedItemPositionCache = new Dictionary<RadTileViewItem, int>();

public MainWindow()
{
	InitializeComponent();
	this.xTileView.PreviewTileStateChanged += XTileView_PreviewTileStateChanged;
}

private void XTileView_PreviewTileStateChanged(object sender, Telerik.Windows.Controls.PreviewTileStateChangedEventArgs e)
{
	if (this.isManualPositionChanged)
            {
                return;
            }

            RadTileViewItem tileViewItem = (RadTileViewItem)e.OriginalSource;
            var header = tileViewItem.Header;
            TileViewItemState oldState = e.TileState;
            TileViewItemState newState = tileViewItem.TileState;

            if (newState == TileViewItemState.Minimized || newState == TileViewItemState.Restored)
            {
                if (maximizedItemPositionCache.ContainsKey(tileViewItem))
                {
                    this.isManualPositionChanged = true;
                    tileViewItem.Position = maximizedItemPositionCache[tileViewItem];
                    this.isManualPositionChanged = false;
                    maximizedItemPositionCache.Remove(tileViewItem);
                }
                if (newState == TileViewItemState.Restored)
                {
                    this.isManualPositionChanged = true;
                    var tileView = sender as RadTileView;
                    foreach (RadTileViewItem item in tileView.Items)
                    {
                        if (item.TileState == TileViewItemState.Maximized)
                        {
                            item.TileState = TileViewItemState.Restored;
                        }
                    }
                    this.isManualPositionChanged = false;
                }
            }
            else if (newState == TileViewItemState.Maximized)
            {
                if (!maximizedItemPositionCache.ContainsKey(tileViewItem))
                {
                    maximizedItemPositionCache[tileViewItem] = tileViewItem.Position;
                }
            }
}

Workaround:
Create a custom style which target type is set to TileViewItemHeader and set it to the HeaderStyle property of the TileView. Then in the custom style, set a custom DataTemplate to the HeaderTemplate property. In this template specify a TextBlock and set its Margin property for instance.

Available in R3 2017 Official Release Version.

The values are switched. 

NewState holds the value of OldState. 
OldState holds the value of NewState 

Allow users to dynamically change the DraggingItem

TextBox (or input control) is in LargeContent of  FluidContentControl in RadTileViewItem. Validation fails and Red border is shown on the TextBox. TileState is changed then it is Maximized again. Validation fails again but no red border is shown.

Add deferred scrolling support

Add GridSplitters between the columns and rows of the TileView so that rows and columns can be resized.

GridSplitters should be available when the tiles are restored or Minimized/Maximized. In the latter case, only a vertical one should be available to resize the minimized tiles' width in respect to the maximized one.

Provide support for changing the ItemContainerStyleSelector runtime.

InvalidOperationException in thrown in design time in certain situations
