Data Template for custom panel

I have created a custom circular panel inherited from panel class in WPF.

This custom control will arrange all its elements in a circular fashion. Now i want to supply the style for its child elements where ever this control is used.

As below mentioned is the usage of my control and i want to supply child items template to it from here as a property some thing like: DataTemplateToUse="{StaticResource ChildItemsTemplate}"

and this control should be intelligent enough to apply the template to all its children elemnts.

<myControl:CirclePanel InnerRadius="250" OuterRadius="300">

</myControl:CirclePanel>

ok i have used it as follows

<Grid Margin="10">
        <ItemsControl Name="icTodoList">
            <ItemsControl.ItemsPanel>
                <ItemsPanelTemplate>
                    <local:CirclePanel  x:Name="CircularPanel" InnerRadius="250" OuterRadius="300" Background="Cornsilk" >
                    </local:CirclePanel>
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <Button Content="{Binding Path=Title}" Margin="0,0,5,5"/>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </Grid>

And dynamically from code behind i am removing the elements from my circle panel so now its throwing the error:

Cannot explicitly modify Children collection of Panel used asItemsPanel for ItemsControl. ItemsControl generates child elements for Panel

Just use an ItemsControl with your panel as ItemsPanel. You get all the properties for data templating and binding items.
