[WPF] AutoCompleteBox: set parameters from code behind

Question

Hi,
I'm using AutoCompleteBox from Codeplex.com
I would set some parameters from code behind... 
In XAML, I defined namespace:
xmlns:toolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit"
After using AutoCompleteBox:
<toolkit:AutoCompleteBox
x:Name="myAutoComplete"
ItemsSource="{Binding Source={StaticResource DomainDataViewModel}, Path=SampleProperties, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
SelectedItem="{Binding Name}"
ValueMemberPath="Name"
ItemTemplate="{StaticResource PropertyBoxItemTemplate}"
MouseLeave="PropertyAutoCompleteBox_MouseLeave"
>
</toolkit:AutoCompleteBox>
If I would set any parameter from code behind, in my.xaml.cs, I not found myAutoComplete, why?
Thanks.

>>I inserted the AutoCompleteBox as DataGridTemplateColumn.CellEditingTemplate.
Then you cannot access it directly from the code-behind as I told you.
>>I would apply a FilterCustom and a ItemFilter.
You could handle the Loaded event for the AutoCompleteBox and set any of its properties in there:
<toolkit:AutoCompleteBox
x:Name="myAutoComplete"
Loaded="myAutoComplete_Loaded"
ItemsSource="{Binding Source={StaticResource DomainDataViewModel}, Path=SampleProperties, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
SelectedItem="{Binding Name}"
ValueMemberPath="Name"
ItemTemplate="{StaticResource PropertyBoxItemTemplate}"
MouseLeave="PropertyAutoCompleteBox_MouseLeave"
>
</toolkit:AutoCompleteBox>
private void myAutoComplete_Loaded(object sender, RoutedEventArgs e)
AutoCompleteBox myAutoComplete = sender as AutoCompleteBox;
//set properties or do whatever here...
myAutoComplete.ValueMemberPath = "Name";
dynamic dataObject = myAutoComplete.DataContext;
//access any properies of the data object in the DataGrid...
How to do filtering is a completely other question that should be asked in a new thread though. It has nothing to do with your original question.
