RadTreeListView - different type children

I don't see a RadTreeListView forum yet, so I'm sticking this here.

I have a list of objects of type SkuForecast. Each SkuForecast has a list of objects of type SkuForecastArchive which has the same columns as the SkuForecast.
I'm trying to setup the RadTreeListView control to work with them, but I'm getting an InvalidCastException error cannot cast type SkuForecastArchive to type SkuForecast

What am I doing wrong?

key support only for chechbox not for selection

Hello,

I'd like to use the telerik treeview with checkbox ability.

but I want only the checkbox functionnality not the selection one.

The issue is to have a treeview and will be able to check an element with "enterkey" press,
no selection, and no expand/collapse. only check/uncheck.

And I also want to check/uncheck throw click on an item.

Thanks for your help

Performance Issue with GridView inside TileView

Hi,

I have encountered a performance issue when adding gridView inside RadTileItem.
CPU starts spinning and process starts to consume lots of memory, until it reaches 2GBs and eventually crashes.

Attached is a snippet from a demo application which presents a standalone gridview performance (which works fine), and the same gridview inside RadTileItem.

XAML:

    
                    <telerik:RadTileView Grid.Row="1">  
        
                        <telerik:RadTileViewItem Header="ABC">  
        
                            <telerik:RadFluidContentControl>                      
        
                                <telerik:RadFluidContentControl.Content> 
        
                                    <TextBlock Text="Maximize this tile." /> 
        
                                </telerik:RadFluidContentControl.Content> 
        
                                <telerik:RadFluidContentControl.SmallContent> 
        
                                    <TextBlock Text="Maximize this tile." /> 
        
                                </telerik:RadFluidContentControl.SmallContent> 
        
                                <telerik:RadFluidContentControl.LargeContent> 
        
                <Grid> 
        
                    <Grid.RowDefinitions> 
        
                        <RowDefinition Height="Auto" /> 
        
                        <RowDefinition /> 
        
                    </Grid.RowDefinitions> 
        
                    <Button Height="20" Content="Generate" Click="Button_Click" /> 
        
                    <telerik:RadGridView Name="telerikGrid" Grid.Row="1" 
        
                                         ItemsSource="{Binding Persons, Mode=OneWay}"

                                         AutoGenerateColumns="False">  
        
                        <telerik:RadGridView.Columns> 
        
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding Path=ID, Mode=OneWay}" Header="ID" IsGroupable="False" IsFilterable="False"  /> 
        
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding Path=Name, Mode=OneWay}" Header="Name" IsGroupable="False" IsFilterable="False"  /> 
        
                        </telerik:RadGridView.Columns> 
        
                    </telerik:RadGridView>
