Dynamics AX2012 Custom Lookup on a Dialog

AX2012 在对话框上自定义查找.

Here the class declaration, don’t forget to extend RunBase.

class DialogLookup extends RunBase
{}

Methods:

Main

Nothing special here either, just get a new instance from your class, to be able to run it later on.

static void main(Args _args)
{DialogLookup            dialogLookup = new DialogLookup();if (dialogLookup.prompt()){dialogLookup.run();}
}

Our dialog

This is where the fun starts. You simply want to get the control from your field, then you call the registerOverrideMethod(…) and as parameter you provide your class name (in this case, the class we are actually writing here) and the method name (this does not have to be lookup!).

protected Object dialog()
{Dialog                      dialog;FormStringControl           control;DialogField                 fieldLookup;dialog = super();// Dialog Titledialog.caption("Aif Adapter");// Field - EDT, LabelfieldLookup = dialog.addField(extendedTypeStr(AifAdapterName), "AifAdapterName:");// Get controlcontrol = fieldLookup.control();// Override lookup methodcontrol.registerOverrideMethod(methodStr(FormStringControl, lookup), methodStr(DialogLookup /* Class name */, lookup /* Method name*/), this);return dialog;
}

The custom lookup

In the last step we will just set up a “normal” (don’t forget the FormStringControl!) lookup method.

public void lookup(FormStringControl _control)
{Query                   query = new Query();QueryBuildDataSource    queryBuildDataSource;SysTableLookup          sysTableLookup = SysTableLookup::newParameters(tableNum(AifAdapter), _control);// Create lookup for AifAdapter's Name and AdapterClassIdsysTableLookup.addLookupField(fieldNum(AifAdapter, Name));sysTableLookup.addLookupField(fieldNum(AifAdapter, AdapterClassId));// Setup queryqueryBuildDataSource = query.addDataSource(tableNum(AifAdapter));sysTableLookup.parmQuery(query);// Perform lookupsysTableLookup.performFormLookup();
}

And this is what it looks like:

Just hit F5 and run your class.

The custom lookup provides us the class id. If I recall it right, the standard AX would provide the EDT Type.
