How to use LoadOnDemand in PXSmartPanel

First of all I want to say that if you do not use "PXTabItem" in your "PXSmartPanel" you should not set LoadOnDemand(by default this attribute has "False" value).

In our example I will show you the difference between using this attribute for "PXSmartPanel" with "True" or "False" values. For that I prepared a short example:

We will use two TabItems (Stock Items for the first and Non-Stock Items for the second).

Let's create them in GraphExt.

public SelectFrom<InventoryItem>.Where<InventoryItem.stkItem.IsEqual<True>>.View StockItemView;
public SelectFrom<InventoryItem>.Where<InventoryItem.stkItem.IsEqual<False>>.View NonStockItemView;

 Let's add button to GraphExt and to the View. For this example we will use the Sales Orders page and add PXSmartPanel to the View.

public sealed class SoOrderEntryExt : PXGraphExtension<SOOrderEntry>
{
    public static bool IsActive() => true;
 
    public PXSelect<SOLine> MyPanelView;
 
    public PXAction<SOOrder> noteAction;
    [PXUIField(DisplayName = "TestNoteButton", MapViewRights = PXCacheRights.Select, MapEnableRights = PXCacheRights.Update)]
    [PXButton(ImageKey = PX.Web.UI.Sprite.Main.DataEntryF)]
    protected IEnumerable NoteAction(PXAdapter adapter)
    {
        if (Base.Transactions.Current != null &&
            MyPanelView.AskExt() == WebDialogResult.OK)
        {
            //extra stuff here if needed when OK is pushed
        }
 
        return adapter.Get();
    }
 
    public SelectFrom<InventoryItem>.Where<InventoryItem.stkItem.IsEqual<True>>.View StockItemView;
    public SelectFrom<InventoryItem>.Where<InventoryItem.stkItem.IsEqual<False>>.View NonStockItemView;
}

 

ASPX. PXSmartPanel:

<px:PXSmartPanel runat="server" ID="PXSmartPanelNote" DesignView="Hidden" LoadOnDemand="false" CreateOnDemand="false" 
                     CaptionVisible="true" Caption="Order Notes" Key="MyPanelView">
        <px:PXTab ID="PXTab123" runat="server" Height="540px" Style="z-index100;" Width="100%">
            <Items>
                <px:PXTabItem Text="NonStockItem" >
                    <Template>
                        <px:PXGrid runat="server" ID="CstPXGrid4" Width="100%" DataSourceID="ds" SyncPosition="True">
                            <Levels>
                                <px:PXGridLevel DataMember="NonStockItemView">
                                    <Columns>
                                        <px:PXGridColumn DataField="StkItem" Width="60" />
                                        <px:PXGridColumn DataField="InventoryCD" Width="70" />
                                    </Columns>
                                </px:PXGridLevel>
                            </Levels>
                        </px:PXGrid>
                    </Template>
                </px:PXTabItem>
                <px:PXTabItem Text="StockItem">
                    <Template>
                        <px:PXGrid runat="server" ID="CstPXGrid5" Width="100%" SyncPosition="True" DataSourceID="ds">
                            <Levels>
                                <px:PXGridLevel DataMember="StockItemView">
                                    <Columns>
                                        <px:PXGridColumn DataField="StkItem" Width="60" />
                                        <px:PXGridColumn DataField="InventoryCD" Width="70" />
                                    </Columns>
                                </px:PXGridLevel>
                            </Levels>
                        </px:PXGrid>
                    </Template>
                </px:PXTabItem>
            </Items>
        </px:PXTab>
        <px:PXPanel runat="server" ID="PXPanel12" SkinID="Buttons">
            <px:PXButton runat="server" ID="btnMyNoteOk" Text="OK" DialogResult="OK" />
        </px:PXPanel>
    </px:PXSmartPanel>

 ASPX.  Callback:

<CallbackCommands>
    <px:PXDSCallbackCommand CommitChanges="true" Name="NoteAction" Visible="False" DependOnGrid="grid" />
</CallbackCommands> 

ASPX. Action Bar:

<px:PXToolBarButton Text="TestNoteButton" DependOnGrid="grid">
    <AutoCallBack Command="NoteAction" Target="ds" />
</px:PXToolBarButton>
