How can I sort a DataGridTemplateColumn on a WPF Toolkit DataGrid?
You need to set the SortMemberPath property on Controls:DataGridTemplateColumn to the name of the CLR property you want to sort on.
Added SortMemberPath="Name" to DataGridTemplateColumn. It started sorting.
<data:DataGridTemplateColumn Header="Name" SortMemberPath="Name" CanUserSort="True">
<DataGridTemplateColumn SortMemberPath="DataDiNascita" Header="Data di nascita" IsReadOnly="True"> <DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <DatePicker SelectedDate="{Binding Path=DataDiNascita}"></DatePicker> </DataTemplate> </DataGridTemplateColumn.CellEditingTemplate> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=DataDiNascita,StringFormat=\{0:dd/MM/yyyy\}}"></TextBlock> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn>
