Hi Walter,

Thank you for posting to Infragistics Community!

I am attaching a sample app demonstrating a simple XamDataGrid with ComboBoxFields, whose ItemsSource is bound to a List from the ViewModel. This binding leverages the custom FieldBinding markup extension. More about this can be read in this page of our documentation.

Regarding the possibility to template a delete button in the fields’ labels, sure, this is also possible. A custom style targeting the LabelPresenter element has to be created and its ContentTemplate can be set to whatever content required, for example:

<Style TargetType="{x:Type igWPF:LabelPresenter}">
     <Setter Property="ContentTemplate">
         <Setter.Value>
             <DataTemplate>
                 <StackPanel Orientation="Horizontal">
                     <TextBlock Text="{Binding}" Width="60"/>
                     <Button Width="20" Click="Button_Click">X</Button>
                 </StackPanel>
             </DataTemplate>
         </Setter.Value>
     </Setter>
 </Style>

In order to delete the field from the button’s handler, one has to retrieve it first, for example:

   private void Button_Click(object sender, RoutedEventArgs e)
   {
       LabelPresenter labelPresenter = (LabelPresenter)Infragistics.Windows.Utilities.GetAncestorFromType((Button)sender, typeof(LabelPresenter), false);
       if(labelPresenter == null)
       {
           return;         
       }
       Field field = labelPresenter.Field;

   }

However, since deleting is an irreversible action, I can also suggest considering simply hiding the field by setting its Visibility property to ‘Collapsed’:

// or hide it and allow it to be turned back form the Field Chooser
 field.Visibility = Visibility.Collapsed;

In this way, if the Field Chooser is also configured to be displayed, users could bring back any hidden fields. Of course, adopt this only, if the scenario allows it.

Now, in case hanlding the Button's Click event is not desried as an approac in your MVVM scenario, you could consider implementing it as a Behavior, for instance. There might be other approaches, depending on your app's configuration, however, this would be out of the scope of Infragistics components. 

In conclusion, please, check out the referenced resources and let me know if they help.

Anyways, I believe you wil find the “Define a Field Layout” documentation topic quite helpful in this case. There you can find snippets of programmatically defining fields for the XamDataGrid.

Doing this based on an unknown object, though, is a matter of coding it separately, for instance, a sample approach would be to iterate the DataTable’s columns and create fields according to their type and set with the column's name. Of course, the implementation for this would be subject to modifications on application level depending on the specific requirements and coding conventions.The fields can be ComboBoxFields as well and their ItemsSource can again be set to an IEnumerable of the local data context. 

I have modified the previous sample to demonstrate a possible approach for this. Please, check it out and let me know if it accurately demonstrates what you’re trying to achieve. Alternatively, please, feel free to provide further details or modify the sample and send it back to me to communicate your ideas.
