Datagrid checkbox styling - wpf

Question

Hello
First sorry for my english.
I have started recently my first project on wpf. I´m styling a custom DataGrid who have been defined programatically (the xaml code doesn´t exists).
I have styled all that i need in my datagrid control except a checkbox that i wrapped inside.
The problem is that in other place of my application i defined a checkbox style how are applying correctly but i can´t apply inside my datagrid.
Actually my datagrid doesn´t throw syntax errors but when the datagrid runs the checkbox styles doesn´t apply.
The style code look like this (its defined in a stylesheet)
... <Setter Property="DataGridCheckBoxColumn.ElementStyle">
<Setter.Value>
<Style TargetType="{x:Type CheckBox}">
<Setter Property="Background" Value="Yellow"/>
<Setter Property="BorderBrush" Value="{DynamicResource NormalBorderBrush}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
<BulletDecorator Background="Transparent">
<BulletDecorator.Bullet>
<Grid Width="13" Height="13">
<Border x:Name="Border" Background="Pink" BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="2,2,2,2"/>
<Path x:Name="CheckMark" Stroke="Green" StrokeThickness="2" SnapsToDevicePixels="False" Data="M1.5000001,1.5833334 L9.7920001,9.6666667 M1.5420001,9.6666667 L9.7083333,1.5000001" Margin="1" ClipToBounds="False" StrokeEndLineCap="Round" StrokeStartLineCap="Round"/>
</Grid>
</BulletDecorator.Bullet>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True"/>
</BulletDecorator>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Setter.Value>
</Setter>...
Its exactly the same that it`s applying in the apliccation.
I´ve read a lot about it but i can´t to apply it, i tried, also, setting the setter property to "DatagridBoundColum.ElementStyle" and also to "CellStyle" but it doesn´t work.
Any suggest??
Thank a lot.

Answer 1

Do it like you would do in xaml:
<UserControl.Resources>
<DataTemplate x:Key="CheckBoxTemplate">
<CheckBox Style="{StaticResource AnyResourceKeyInApplciation}"/>
</DataTemplate>
</UserControl.Resources>
<DataGrid x:Name="dataGrid" />
this.dataGrid.Columns.Add(new DataGridTemplateColumn
{
CellTemplate = this.Resources["CheckBoxTemplate"] as DataTemplate
}
);

Thanks for your Reply vorrtex.
I didn´t apply it exactly but it helped me to find the solution, however i would have liked not to modify the VB code and only to modify it the xaml style tag.
I find an object how simplify this task. The syntax it´s the following:
column2.ElementStyle = Application.Current.FindResource("CheckBoxStyle")
It´s applying style ok inside the datagrid. But actually it´s placing at left border of the cell. I´ll try to find why.
Thanks again.

You can try this
<Controls:DataGridCheckBoxColumn Header="Homme" Binding="{Binding Homme}">
<Controls:DataGridCheckBoxColumn.ElementStyle>
<Style TargetType="CheckBox" BasedOn="{StaticResource {x:Type CheckBox}}">
<Setter Property="Margin" Value="4,0,0,0"/>
</Style>
</Controls:DataGridCheckBoxColumn.ElementStyle>
</Controls:DataGridCheckBoxColumn>
