XAML DataTemplate with parameter - wpf

Question

I have a data template that is:
<DataTemplate x:Key="CalDescButton">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock
Grid.Row="0"
Grid.RowSpan="2"
Grid.Column="0"
Grid.ColumnSpan="2"
Style="{StaticResource LargeIconStyle}"
Text="" />
<TextBlock
Grid.Row="0"
Grid.Column="1"
Foreground="Transparent"
Style="{StaticResource MediumIconStyle}"
Text="" />
<TextBlock
Grid.Row="1"
Grid.Column="1"
Foreground="Transparent"
Style="{StaticResource MediumIconStyle}"
Text="" />
<TextBlock
Grid.Row="0"
Grid.Column="1"
Foreground="Transparent"
Style="{StaticResource MediumIconStyle}"
Text="" />
<TextBlock
Grid.Row="1"
Grid.Column="0"
Foreground="Transparent"
Style="{StaticResource MediumIconStyle}"
Text="" />
<TextBlock
Grid.Row="1"
Grid.RowSpan="2"
Grid.Column="0"
Margin="0,-6,0,0"
Foreground="Aqua"
Style="{StaticResource XSmallIconStyle}"
Text="" />
</Grid>
</DataTemplate>
Then I have other 6 where the only thing that changes is the Text Char code.
Those templates are applied to buttons:
<ToggleButton
Command="{Binding CmdSetSorting, Mode=OneWay}"
CommandParameter="CalAsc"
ContentTemplate="{StaticResource CalDescButton}" />
The question is: can I pass a variable to the template and use it in the Text="" instead of having 6 different templates just for that?
How can I do it?
Just to be clear I'd like to have something like:
<DataTemplate x:Key="IconButton">
and then:
ContentTemplate="{StaticResource IconButton ()}" />

Answer 1

set Content property of Button:
<ToggleButton
Command="{Binding CmdSetSorting, Mode=OneWay}"
CommandParameter="CalAsc"
Content=""
ContentTemplate="{StaticResource CalDescButton}" />
it should become DataContext of root element in DataTemplate (because it is ContentTemplate) and will be accessible by Binding:
<TextBlock
Grid.Row="0"
Grid.RowSpan="2"
Grid.Column="0"
Grid.ColumnSpan="2"
Style="{StaticResource LargeIconStyle}"
Text="{Binding}" />
