Binding WPF DatagridCell to the source - wpf

Question

My original datagrid does have a few columns wherein the bound value is bool.[By default this would show up as check boxes]
I have defined a cell template and could create
I would like to use a common datagrid controltemplate for this, like the one defined below.
However it doews not bring in the binding value - it shows up blank.
Could someone help spot me on what I am doing wrong?
<Style x:Key="dgCellBool" TargetType="{x:Type DataGridCell}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Ellipse>
<Ellipse.Height>10</Ellipse.Height>
<Ellipse.Width>10</Ellipse.Width>
<Ellipse.Style>
<Style TargetType="Ellipse">
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Binding}" Value="True">
<Setter Property="Fill" Value="Red"></Setter>
</DataTrigger>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Binding}" Value="False">
<Setter Property="Fill" Value="Green"></Setter>
</DataTrigger>
</Style.Triggers>
</Style>
</Ellipse.Style>
</Ellipse>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Thanks

Answer 1

You are trying to bind Binding property of DataGridCell but DataGridCell dont have any Binding property. Yoy should set Path=Column.Binding. DataGridCell has Column property which further has Binding Property.
Binding="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Column.Binding}"
I hope this will help.

Answer 2

You need to provide a ContentPresenter to present the content and make sure you add the Border that you will lose from the original Template:
<Style TargetType="{x:Type DataGridCell}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridCell}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter VerticalAlignment="Center"
HorizontalAlignment="Center" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
UPDATE >>>
If you want your Ellipse instead of a Border, just add it back in with a Grid... Ellipse objects cannot have any content:
<Style x:Key="dgCellBool" TargetType="{x:Type DataGridCell}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridCell}">
<Grid>
<Ellipse Height="10" Width="10">
<Ellipse.Style>
<Style TargetType="Ellipse">
<Setter Property="Fill" Value="Red" />
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={
RelativeSource TemplatedParent}, Path=Binding}" Value="False">
<Setter Property="Fill" Value="Green" />
</DataTrigger>
</Style.Triggers>
</Style>
</Ellipse.Style>
</Ellipse>
<ContentPresenter VerticalAlignment="Center"
HorizontalAlignment="Center" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
