[SOLVED] How do you add an unbound 'select' button to an existing DAC for a custom process screen?

How do you add an unbound 'select' button to an existing DAC for a custom process screen?

I have a custom process screen using the POOrder DAC as a filtered list of records to process. The issue I'm having is how to add the 'Select' checkbox to an existing DAC? Is that just a standard DAC extension?

If so, how would that would work when specifying the Detail View for the grid... I can't seem to find any examples online - the training just specifies adding the unbound (PXBool) 'Select' field directly to the existing DAC, but that's a DAC that is created in the training and not an existing stock Acumatica DAC like POOrder.

Solution

You can declare an unbound boolean DAC field named Selected as instructed.

#region Selected
public abstract class selected : PX.Data.BQL.BqlBool.Field<selected> { }

protected bool? _Selected = false;
[PXBool]
[PXDefault(false, PersistingCheck = PXPersistingCheck.Nothing)]
[PXUIField(DisplayName = "Selected")]
public virtual bool? Selected
{
    get
    {
        return _Selected;
    }
    set
    {
        _Selected = value;
    }
}
#endregion

By naming convention Acumatica processing delegate will detect the column named Selected and will apply different behavior to it. It is possible to use a different column name by calling the processing data view SetSelected method.

public PXProcessing<DAC> ProcessingDataView;

public GraphConstructor()
{
    ProcessingDataView.SetSelected<DAC.columnName>();
    ProcessingDataView.SetProcessDelegate(ProcessingDelegateMethod);
}

Selected is the default name for the data field for this specific check box; you can define the data field with any name and override the default Selected name in the graph constructor with the SetSelected() method of the PXProcessing class.
