WPF DataTemplate and columns definition

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>
