5 MORE AX 2012 TIPS AND TRICKS

Multi-select on form datasource grid in AX

There is a difference in iterating the selected records on a form datasource depending on how and what the user has selected.

Suppose we have a form with Grid multi select property = TRUE. The form has button with it clicked method overwritten.

There are three ways to get selected records:

1. Iterating marked records on the grid

Here is some sample code:

void clicked()
{
    InventItemGroup itemGroup;

    itemGroup = InventItemGroup_DS.getFirst(1);
 
    while (itemGroup.RecId != 0)
    {
        info(itemGroup.ItemGroupId);

        itemGroup = InventItemGroup_DS.getNext();
    }
}

2. Getting the current record by just accessing the datasource directly

Here is some sample code:

void clicked()
{
    info(InventItemGroup.ItemGroupId);
}

3. Using MultiSelectionHelper class

The MultiSelectionHelper class provides an interface to work with multiple selected records on a form data source.

Here is some sample code:

void clicked()
{
    InventItemGroup   itemGroup;
    MultiSelectionHelper  helper = MultiSelectionHelper::construct();
    
    helper.parmDatasource(InventItemGroup_DS);

    itemGroup = helper.getFirst();
    while (itemGroup.RecId != 0)
    {
        info(itemGroup.ItemGroupId);

        itemGroup = helper.getNext();
    }
}
