How to open multiple Purchase orders in new browser tabs

static public void initFromPurchTable(FormDataSource _formDS)
{​
	PurchTable      currentPurchTable;
	Browser         browser = new Browser();
	for (currentPurchTable = _formDS.getFirst(true) ? _formDS.getFirst(true): _formDS.cursor();
	currentPurchTable;
	currentPurchTable= _formDS.getnext())
	{​
		var generator     = new Microsoft.Dynamics.AX.Framework.Utilities.UrlHelper.UrlGenerator();
		var currentHost   = new System.Uri(UrlUtility::getUrl());
		generator.HostUrl = currentHost.GetLeftPart(System.UriPartial::Authority);
		generator.Company = curext();
		generator.MenuItemName = 'PurchTableListPage';
		generator.Partition = getCurrentPartition();
		// repeat this segment for each datasource to filter
		var requestQueryParameterCollection = generator.RequestQueryParameterCollection;
		requestQueryParameterCollection.AddRequestQueryParameter(
																'PurchTable',
																'PurchId', currentPurchTable.PurchId
																);
		System.Uri fullURI = generator.GenerateFullUrl();
		browser.navigate(fullURI.AbsoluteUri, true);
	}​
}​

Operating with system defined buttons in form Action pane

Say, we have to reference Edit button.

For this we use the macro #define.SystemDefinedViewEditButton('SystemDefinedViewEditButton')

The whole list is present in SysSystemDefinedButtons macro


Code snippet for your active method in name_DS

int active()
        {
            
            #SysSystemDefinedButtons
 
            ret = super();
 
         < ... >
            FormCommandButtonControl editButton = element.control(element.controlId(#SystemDefinedViewEditButton)) as FormCommandButtonControl;
            editButton.enabled(name_ds.allowEdit());
 
            return ret;
        }

Accessing FormDataSource

Say, we need to change the form data source sorting order or any other more complex change.

This is an old but good note by Vania Kashperuk about the subject in AX 2012.

public void init()
{
    super();
    this.queryBuildDataSource().addSortField(fieldNum(myDescartesInbound, RecId), SortOrder::Descending);
}
