I've modified your code so that it uses the tips shown in help article I gave you. Here it is:
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
List<string> strList = new List<string>();
RadTileView enterpriseView = new RadTileView();
enterpriseView.TileStateChanged += new System.EventHandler<Telerik.Windows.RadRoutedEventArgs>(EnterpriseView_TileStateChanged);
for (int i = 0; i < 4; i++)
{
RadTileViewItem modelTypeItem = new RadTileViewItem();
modelTypeItem.Header = "Tile " + i;
RadFluidContentControl contentControl = new RadFluidContentControl();
// LARGE CONTENT
ScrollViewer objscrollLarge = new ScrollViewer();
StackPanel panel = new StackPanel();
panel.Orientation = Orientation.Vertical;
SolidColorBrush panelBackground = new SolidColorBrush();
panelBackground.Color = Color.FromArgb(255, 200, 239, 241);
panel.Background = panelBackground;
for (int index = 0; index < 3; index++)
{
TextBlock txtBlk = new TextBlock();
txtBlk.Text = "Large Content TextBlock : " + (index + 1);
strList.Add(txtBlk.Text);
panel.Children.Add(txtBlk);
}
objscrollLarge.HorizontalScrollBarVisibility = System.Windows.Controls.ScrollBarVisibility.Auto;
objscrollLarge.VerticalScrollBarVisibility = System.Windows.Controls.ScrollBarVisibility.Auto;
objscrollLarge.Content = panel;
contentControl.LargeContent = objscrollLarge;
// NORMAL CONTENT
ScrollViewer objScrollNormal = new ScrollViewer();
System.Windows.Controls.ListBox listbox = new System.Windows.Controls.ListBox();
StackPanel stkNormal = new StackPanel();
stkNormal.Orientation = Orientation.Vertical;
for (int index = 0; index < 3; index++)
{
System.Windows.Controls.ListBoxItem item = new System.Windows.Controls.ListBoxItem();
item.Content = strList[index];
listbox.Items.Add(item);
}
stkNormal.Children.Add(listbox);
objScrollNormal.HorizontalScrollBarVisibility = System.Windows.Controls.ScrollBarVisibility.Auto;
objScrollNormal.VerticalScrollBarVisibility = System.Windows.Controls.ScrollBarVisibility.Auto;
objScrollNormal.Content = stkNormal;
contentControl.Content = objScrollNormal;
// SMALL CONTENT
ScrollViewer objScrollSmall = new ScrollViewer();
System.Windows.Controls.ListBox listboxSmall = new System.Windows.Controls.ListBox();
StackPanel stkSmall = new StackPanel();
stkSmall.Orientation = Orientation.Vertical;
for (int index = 0; index < 3; index++)
{
System.Windows.Controls.ListBoxItem item = new System.Windows.Controls.ListBoxItem();
item.Content = strList[index];
listboxSmall.Items.Add(item);
}
stkSmall.Children.Add(listboxSmall);
objScrollSmall.HorizontalScrollBarVisibility = System.Windows.Controls.ScrollBarVisibility.Auto;
objScrollSmall.VerticalScrollBarVisibility = System.Windows.Controls.ScrollBarVisibility.Auto;
objScrollSmall.Content = stkSmall;
contentControl.SmallContent = objScrollSmall;
// We need to set the ContentChangeMode to Manual so we can use the logic in EnterpriseView_TileStateChanged
contentControl.ContentChangeMode = ContentChangeMode.Manual;
modelTypeItem.Content = contentControl;
enterpriseView.Items.Add(modelTypeItem);
}
LayoutRoot.Children.Add(enterpriseView);
}
private void EnterpriseView_TileStateChanged(object sender, Telerik.Windows.RadRoutedEventArgs e)
{
RadTileViewItem item = e.OriginalSource as RadTileViewItem;
RadFluidContentControl fluidContentControl = item.Content as RadFluidContentControl;
switch (item.TileState)
{
case TileViewItemState.Maximized:
fluidContentControl.State = FluidContentControlState.Large;
break;
case TileViewItemState.Minimized:
fluidContentControl.State = FluidContentControlState.Small;
break;
case TileViewItemState.Restored:
fluidContentControl.State = FluidContentControlState.Normal;
break;
default:
break;
}
}
