WPF DataTemplate and columns definition - wpf

Question

I need to improve the render of my grid. I have a template:
<DataTemplate x:Key="ubitTemplateService" DataType="{x:Type data:uBit}">
<Grid HorizontalAlignment="Stretch" x:Name="grdBit">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="MAMC" />
<ColumnDefinition Width="Auto" SharedSizeGroup="ID" />
<ColumnDefinition Width="Auto" SharedSizeGroup="lblVIS" />
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Content="{Binding FIELD_Mac, Mode=OneWay}" Style="{StaticResource labelStyle1}" />
<TextBlock Grid.Column="1" Text="{Binding Name}" Style="{StaticResource txtBlockStyle2}" />
<Label Grid.Column="1" Content="{Binding Show.Caption}" Style="{StaticResource labelStyle4}" />
</Grid>
</DataTemplate>
Basically for each record of my collection, a grid is rendered but as I have 300 or more record, the whole render takes about 2-3 seconds (each template was rendered into a Listbox)
I would want to change the layout and use a datagrid as follows:
<DataGrid x:Name="gridDati" BorderBrush="#abadb3" CanUserSortColumns="true" Margin="8,7,5,8">
<DataGrid.Columns>
<DataGridTemplateColumn Header="Name" CellTemplateSelector="{StaticResource DataTemplateSelector}" />
</DataGrid.Columns>
</DataGrid>
and I would want to use a datatemplate in order to render the columns, which may changes base on my datatype. The template selector is:
<local:DataconfigTemplateSelector ubitTemplateAv="{StaticResource ubitTemplateAv}" x:Key="DataTemplateSelector" />
The problem is that I want to put into my datatemplate the definition of DataGrid columns, for example a DataGridTextColumn:
<DataTemplate x:Key="ubitTemplateAv">
<StackPanel>
...
</StackPanel>
</DataTemplate>
How can I put into my datatemplate the columns definition like?
<DataGridTextColumn Binding="{Binding Name, UpdateSourceTrigger=PropertyChanged, Mode=OneWay}" Header="Nome" Foreground="Black" IsReadOnly="True" x:Name="colName">
<DataGridTextColumn.ElementStyle>
<Style TargetType="TextBlock">
<Setter Property="Padding" Value="4,7,4,6" />
</Style>
</DataGridTextColumn.ElementStyle>
</DataGridTextColumn>
<DataGridTextColumn Binding="{Binding SurName, UpdateSourceTrigger=PropertyChanged, Mode=OneWay}" Header="SurName" Foreground="Black" IsReadOnly="True" x:Name="colSurName">
<DataGridTextColumn.ElementStyle>
<Style TargetType="TextBlock">
<Setter Property="Padding" Value="4,7,4,6" />
</Style>
</DataGridTextColumn.ElementStyle>
</DataGridTextColumn>

Answer 1

the key is to use DataGridTemplateColumn instead of DataGridTextColumn.
Then you can do this:
<DataGridTemplateColumn
Width="80">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Foo}" Padding="4,7,4,6"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
