DataGridTemplateColumn

You can use this column type to customise the display and editing for a data grid column.

There are two data templates which you define as attached properties:

Data TemplateDescription
CellTemplate The display (not being edited) presentation of the column value.
CellEditingTemplate The editing template for the column value.

If you do not set a editing template, the column will stay read-only.

Example

This example adds a numeric up-down control when the age property for a person is being edited:

<Window ...
xmlns:model="using:AvaloniaControls.Models" >

<DataGrid Margin="20" ItemsSource="{Binding People}"
GridLinesVisibility="All"
BorderThickness="1" BorderBrush="Gray">
<DataGrid.Columns>
<DataGridTextColumn Header="First Name" Width="2*"
Binding="{Binding FirstName}" />
<DataGridTextColumn Header="Last Name" Width="2*"
Binding="{Binding LastName}" />

<DataGridTemplateColumn Header="Age">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate DataType="model:Person">
<TextBlock Text="{Binding AgeInYears, StringFormat='{}{0} years'}"
VerticalAlignment="Center" HorizontalAlignment="Center" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate DataType="model:Person">
<NumericUpDown Value="{Binding AgeInYears}"
