Assign Tabitem Style from xaml in Code behind

Question

Hi
I have a style defined for TabItem in XAML.
I am generating the TabItem Dynamically and i want to add the Style create from XAML to the tabitem that is created dynamicaly.
Here is my XAML code
<TabControl Name="tc" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Background="White">
<TabControl.Resources>
<Style TargetType="TabItem" x:Key="hi">
<Setter Property="VerticalAlignment" Value="Bottom" />
<Setter Property="HorizontalAlignment" Value="Left" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border" Background="LightBlue" BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="2,12,12,2" > <ContentPresenter x:Name="ContentSite"
VerticalAlignment="Center"
HorizontalAlignment="Center"
ContentSource="Header"
Margin="12,2,12,2"/>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter TargetName="Border" Property="Background" Value="LightSkyBlue" />
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="Border" Property="Background" Value="GhostWhite" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</TabControl.Resources>
</TabControl
in code behind i am trying to assign the style
private void example_Click_1(object sender, RoutedEventArgs e)
try
ExampleGrid ex = new ExampleGrid();
Close_Tab theTabItem = new Close_Tab();
theTabItem.Title = "my Grid";
tc.Items.Add(theTabItem);
theTabItem.Style = (Style)FindResource("hi");
theTabItem.Content = ex;
theTabItem.Focus();
catch (Exception ee)
MessageBox.Show(ee.Message);
I am getting an exception saying resource hi is not found
Note: hi is the name of the style.
Please suggest me the solution for this.
Thanks All

I believe if you remove x:key attribute from the tab style
<Style TargetType="TabItem"> ... </Style>
then it will be applied to all tabs.
If this not works then take out your style definition from <TabControl.Resources> and put it the resource of parent control which contains TabControl
e.g
<UserControl ...>
<UserControl.Resources>
<Style TargetType="TabItem"> ... </Style> // don't add x:key attribute
</UserControl.Resources>
<TabControl> .. </TabControl>
</UserControl>
