New item in maximized size

[Radek]

Helo,
I have a problem with the correct rendering of items when I need new added itmes.
When I add new tileViewItem is everything alright. But I want to be the last tileViewItem added to the maximum size.
In this case are next minimized items (in my case, every third) displayed wrong. 
When I resize the window, items are rendered correctly.

In XAML I have
            <telerik:RadTileView x:Name="myTileView" MinimizedColumnWidth="200">
            </telerik:RadTileView>
In .cs file


        private void Button_Click(object sender, RoutedEventArgs e) {

            RadTileViewItem tileItem = new RadTileViewItem();
          
            RadFluidContentControl contentControl = new RadFluidContentControl();
            contentControl.SmallContent = "Small content - demo";
            contentControl.Content = "Content - demo";
            contentControl.LargeContent = "Content - large";
            contentControl.State = FluidContentControlState.Large;

            tileItem.Content = contentControl;

   //tileItem.TileState = TileViewItemState.Maximized;

            myTileView.Items.Add(tileItem);
        }

Thanks for help.

Hi Radek,

 Thank you for the bug report. We'll look into this problem and I hope that it'll be fixed in the next couple of weeks. For now I can give you a work around - if you want the just added item to be maximized you should use the MaximizedItem property of the RadTileView like this:

private void Button_Click(object sender, RoutedEventArgs e)
{
     RadTileViewItem tileItem = new RadTileViewItem();

     RadFluidContentControl contentControl = new RadFluidContentControl();
     contentControl.SmallContent = "Small content - demo";
     contentControl.Content = "Content - demo";
     contentControl.LargeContent = "Content - large";
     contentControl.State = FluidContentControlState.Large;

     tileItem.Content = contentControl;

     this.myTileView.Items.Add(tileItem);
     this.myTileView.MaximizedItem = tileItem;
}

I updated your telerik account and if you have further questions feel free to ask.

Hi Vladislav, after 6 mounts we've similar problem. We previously used mehod onButtonClick
a now we use MVVM. We need to be newly added item to appear as maximized.

Here is XAML code.

<cc:TileView Name="tvAdmin" MinimizedColumnWidth="200" ItemsSource="{Binding Workspaces}"></cc:TileView>

<Style TargetType="cc:TileView">
    <Setter Property="PreservePositionWhenMaximized" Value="True" />
    <Setter Property="telerik:TileViewPanel.IsVirtualized" Value="True" />
    <Setter Property="TileStateChangeTrigger" Value="SingleClick" />
    <Setter Property="RowHeight" Value="160" />
    <Setter Property="ColumnWidth" Value="180" />
    <Setter Property="ItemTemplate" Value="{StaticResource CloseAbleViewItemTemplate}" />
</Style>

And code in 

namespace WPF.Library.Controls{
    public class TileView : Telerik.Windows.Controls.RadTileView  {

        static TileView () {
            // DefaultStyleKeyProperty.OverrideMetadata(....));
        }

        public TileView (){
            this.MaximizeMode = TileViewMaximizeMode.One;
        }

        protected override void OnItemsChanged (NotifyCollectionChangedEventArgs e) {
            base.OnItemsChanged(e);

            if (e.Action == NotifyCollectionChangedAction.Add) {
                if (e.NewStartingIndex > 0){
                    SelectedItem = Items[e.NewStartingIndex];
                    this.MaximizedItem = SelectedItem;
                }
            }
            return;
        }
    }
}

In this solution is a new item appears as a maximized but disappear all previous items. If I close
 this item with other items displayed correctly.

Can you please suggest a correct solution.
Thank you Radek Bastinec.

Hello Josef,
Thank you for the feedback! There seems to be a problem in your scenario so I logged it in our PITS under the name "In binding scenarios if you set a newly added item to be maximized you get wrong layout". For now there's a workaround that you can use - you can override the PrepareContainerForOverride and in it set the TileState of the new item to Maximized.
I've updated your telerik account and for further information please examine the attached project.
